Description

  The present invention relates to a task display device, a task display method, and a task display program for displaying a task in management of a project including a plurality of tasks.

  Generally, in each industry such as the manufacturing industry and the software industry, planning operations such as production planning, operation planning, and project planning are performed. For example, an administrator who manages the execution of a project plan divides a project into multiple units of work, and assigns a schedule for executing the work, a person in charge of the work, etc. I manage. This unit of work is called a task, and managing a project divided into tasks in this way is called task management. The tasks that make up the project may have dependencies on each other. For example, the output result of task A execution may be used as an input for task B execution, and the output result of task B execution may be used as an input for task C execution. In this case, the task A, the task B, and the task C cannot independently perform the task and have a dependency relationship with each other.

  A Gantt chart may be used as a display method for grasping a process plan related to such a project task. In the Gantt chart, information such as the task name, the project name of the project to which the task belongs, the name of the person in charge, the scheduled start date and the scheduled end date of the task are displayed in a band-like list format for each task.

  Further, as another display method for grasping the process plan related to the task, there is a case where the dependency relation of the task is displayed as shown in FIG. In the display example shown in FIG. 16, it is possible to grasp the dependency relationship in which the task 2 is started after the task 1 is finished and the task 3 is started after the task 2 is finished.

On the other hand, there is a method of displaying the tasks assigned to each resource in time series so that the task assigned to the resource as the person in charge can be grasped (for example, described in Patent Document 1). In Patent Document 1, the processing capability of each resource to execute a task is considered, and the resource, the task that the resource is in charge of, and the task dependency are displayed in association with each other. Patent Document 1 also describes a method for displaying a task scheduled to be executed within a certain period.
JP 2004-227051 A

  In the conventional display method as described above, the task in the project is focused on the person in charge and the execution period of the task. Therefore, in the case of the conventional Gantt chart, it is unclear to grasp the dependency relationship between each task, and it is difficult to grasp the task assigned to a predetermined person in charge. Further, when all the dependency relationships of the tasks belonging to the project are displayed as shown in FIG. 16, the scheduled execution date of the resource and the task is grasped from the Gantt chart as shown in FIG. In addition to being able to do so, the more tasks that are involved in a project and the more complex the dependencies, the more difficult it becomes to understand the task dependencies.

  In addition, a certain task may involve not only one project but also a plurality of projects. For example, the output result of the execution of task A belonging to the first project is used as an input for execution of task B belonging to the first project and an input of execution of task C belonging to the second project. When there are tasks related to such a plurality of projects, it is difficult to grasp the dependency relationship with a task belonging to another project beyond the project to which the target task belongs by the conventional display method.

  Therefore, the present invention has been made in view of the above circumstances, and its purpose is to display a task that correlates with a task attribute in association with the task, and to support steady execution of the project and task display. A method and a task display program are provided.

  In order to solve the above-described problem, a task display device according to a first feature includes, in managing a project including a plurality of tasks, a predetermined task, a pre-task executed before execution of the predetermined task, and the predetermined A task display device that associates and displays a post-task executed after execution of the task, and stores a task identifier for identifying the predetermined task and the pre-task, and project management data associated with the pre-task identifier Project management data storage processing unit stored in the device, and from the storage device using the task identifier as a key, the previous task search unit for searching for a previous task identifier associated with the task identifier, and from the storage device using the task identifier as a key The task associated with the previous task identifier using the previous task identifier for identifying the predetermined task as a key. It has a task search unit after searching an identifier as a task after said predetermined task, and a display control unit for displaying tasks and latter task before retrieved in association with predetermined task.

  In addition, the task display method according to the second aspect of the present invention provides a predetermined task, a pre-task executed before execution of the predetermined task, and the predetermined task in managing a project including a plurality of tasks. Display method that associates and displays a post-task to be executed after the execution of the task, and stores a task identifier for identifying the predetermined task and the pre-task, and project management data associated with the pre-task identifier in the storage device Project management data storage processing step to be stored, a previous task search step for searching a previous task identifier associated with the task identifier from the storage device using the task identifier as a key, and a previous task for identifying a predetermined task from the storage device Using the identifier as a key, the task identifier associated with the previous task identifier is the predetermined task. It has a task searching step after searching the task, and a display control step of displaying the task and latter task before retrieved in association with predetermined task after.

  Furthermore, the task display program according to the third aspect of the present invention provides a predetermined task, a previous task executed before execution of the predetermined task, and the predetermined task in managing a project including a plurality of tasks.

Next, the best mode for carrying out the present invention will be described with reference to the drawings. In the following description of the drawings, the same or similar parts are denoted by the same or similar reference numerals.
(First embodiment)
FIG. 1 is a functional block diagram illustrating the configuration of the task display device 1 according to the first embodiment of the present invention, and FIG. 2 is a diagram illustrating the hardware configuration of the task display device 1.
As shown in FIG. 1, the task display device 1 has a storage unit that stores a previous task search unit 11, a subsequent task search unit 12, a display control unit 13, a storage processing unit 14, a reading unit 15, and project management data 16. ing.

  As shown in FIG. 2, the task display device 1 includes a central processing control device 101, a ROM (Read Only Memory) 102, a RAM (Random Access Memory) 103, and an input / output interface 109, which are connected via a bus 110. It is connected. An input device 104, a display device 105, a communication control device 106, a storage device 107, and a removable disk 108 are connected to the input / output interface 109.

  The central processing control device 101 reads out and executes a boot program for starting the task display device 1 from the ROM 102 based on an input signal from the input device 104, and further reads out an operating system stored in the storage device 107. Further, the central processing control device 101 controls various devices based on input signals from the input device 104, the communication control device 106, etc., reads out programs and data stored in the RAM 103, the storage device 107, etc., and loads them into the RAM 103. At the same time, based on a program command read from the RAM 103, a series of processes described later, such as data calculation or processing, is realized.

  The input device 104 includes input devices such as a keyboard and a mouse through which an operator inputs various operations. The input device 104 generates an input signal based on the operation of the operator, and inputs via the input / output interface 109 and the bus 110. It is transmitted to the central processing control apparatus 101.

  The display device 105 is a CRT (Cathode Ray Tube) display, a liquid crystal display, or the like, and displays an output signal input from the central processing control device 101 via the bus 110 and the input / output interface 109.

  The communication control device 106 is a device such as a LAN card or a modem, and is a device that connects the task display device 1 that executes the task display program according to the present invention to a communication network such as the Internet or a LAN. The communication control device 106 transmits data received from the communication network as an input signal to the central processing control device 101 via the input / output interface 109 and the bus 110. Further, the communication control device 106 transmits data received from the central processing control device 101 via the input / output interface 109 and the bus 110 as an output signal to the communication network.

  The storage device 107 is a semiconductor storage device, a magnetic disk device, or the like, and stores programs and data executed by the central processing control device 101. The removable disk 108 is an optical disk or a flexible disk, and signals read / written by the disk drive are transmitted / received to / from the central processing control apparatus 101 via the input / output interface 109 and the bus 110. The storage device 107 of the task display device 1 stores a task display program and project management data 16. By reading the task display program into the central processing control device 101, the task display device 1 having the functions of the previous task search unit 11, the subsequent task search unit 12, the display control unit 13, the storage processing unit 14, and the reading unit 15 is configured. Is done.

  The previous task retrieval unit 11 retrieves a previous task of a predetermined task from the project management data 16 stored in the storage device 107. The “previous task” is a task that needs to be completed before execution of a predetermined task. For example, when the task 2 is “data generation”, the task 1 that is the previous task is the work content such as creating data used for executing the task 2. The previous task search unit 11 repeats the process of searching for the previous task for the searched previous task, and extracts all previous tasks that must be executed before the execution of the predetermined task.

  The post-task search unit 12 searches for post-tasks of a predetermined task from the project management data 16 stored in the storage device 107. A “post-task” is a task that needs to be started after execution of a predetermined task. For example, when the task 1 is “data generation”, the task 2 which is a task after that is the work content such as creation of data using the data generated by the execution of the task 1. The post-task search unit 12 further repeats the process of searching for the post-task after the search, and extracts all post-tasks that must be executed after execution of the predetermined task.

The display control unit 13 associates the searched previous task with a predetermined task, and displays the searched post-task in association with the predetermined task.
The reading unit 15 reads the project management data 16 stored in the storage device 107 and stores it in the RAM 103 or the like.

  As shown in FIG. 3, the project management data 16 has a record in which a task name, a previous task name, a resource name that is a task attribute, a scheduled start date, and a scheduled end date are associated. “Task name” identifies a task that is a work item of a project. The “resource name” is an identifier of a resource that operates the task. In the following description, a resource is described as representing a person in charge of a task. “Scheduled start date” is a scheduled date on which the task starts. The “scheduled end date” is a scheduled date when the task ends. “Previous task name” is an identifier of the previous task. The project management data 16 is data relating to project process management, and is input via the input device 104, for example. The project management data 16 is stored in the storage device 107 by the storage processing unit 14 installed in the central processing control device 101.

  In FIG. 3, “Task 1” indicates that the person in charge A starts on April 1, 2005 and ends on April 2, 2005. The previous task of “task 1” is “NULL”, meaning that there is no previous task in “task 1”. Thus, when the previous task is “NULL”, there is no previous task in the task. In FIG. 3, “task 3” indicates that the person in charge C starts on April 4, 2005 and ends on April 6, 2005. The previous task of “task 3” is “task 1”, and “task 3” indicates that “task 1” starts after “task 1” ends. In the example shown in FIG. 3, there is one record for each task. However, when there are a plurality of records for a predetermined task, it indicates that a plurality of previous tasks exist. That is, it indicates that it is a requirement that a plurality of tasks be completed before a predetermined task is executed.

  FIG. 4 is a Gantt chart that displays the project process plan shown by the project management data 16 in FIG. In the Gantt chart shown in FIG. 4, the time is shown in the horizontal direction, the type of task is shown in the vertical direction, and the correlation of each task is shown using arrows. Each task name is associated with the name of a person in charge of the task as a resource name. The Gantt chart shown in FIG. 4 includes all the tasks included in the project. In order to understand the correlation between specific tasks, it is necessary for the user to follow the previous and subsequent tasks.

(Task display process)
FIG. 5 is a flowchart illustrating task display processing of the task display device 1 according to the first embodiment. By this task display process, the task display device 1 displays the dependency relationship of the selected task. The dependency displayed in this display process includes 2 searched for the primary previous task as the base task in addition to the primary previous task and the primary post task searched for the selected task as the base task. The secondary post-task searched using the next pre-task and the primary post-task as the base task is included. In addition, in the dependency relationship, the third previous task searched using the secondary previous task as the base task, the fourth previous task searched using the third previous task as the base task, and the second post task as the base task. It includes all previous tasks and subsequent tasks related to the selected task, such as a retrieved fourth post task and a fourth post task retrieved using the third post task as a base task.

  First, when the task display process is started based on a display request input via the input device 104, the user selects a predetermined task for displaying the dependency relationship (S001). When a predetermined task is selected in step S001, the reading unit 15 reads the project management data 16 from the storage device 107 (S002).

  Thereafter, the previous task retrieval unit 11 retrieves the previous task from the project management data 16 using the predetermined task selected in step S001 as a base task, and stores the retrieved previous task in a work memory such as the RAM 103 (S004). .

  When the previous task is searched using the predetermined task selected in step S001 as a base task, the previous task search unit 11 further searches the previous task using the previous task searched by repeating the search process of the previous task as a base task. Similarly, the retrieved previous task is stored in the memory (S004). The previous task search unit 11 repeats the process of searching for the previous task and storing the search result in the memory until all previous tasks to be searched are set as the base task and the search for the previous task is completed (S003). The term “until the previous task search is completed” means that the searched previous task becomes “NULL”.

  For example, when using the project management data 16 in which the task shown in FIG. 3 is associated with the previous task of the task, the previous task search unit 11 searches the project management data 16 for the previous task name associated with the task name. By doing so, the previous task of the predetermined task is searched.

  Specifically, when “task 3” is selected as the predetermined task in step S001, the previous task search unit 11 extracts and extracts a record whose task name is “task 3” in the project management data 16 “Task 1”, which is the name of the previous task in the record, is set as the primary previous task. In the example shown in FIG. 3, only “task 1” is the task before “task 3”, but there may be a plurality of tasks before the task.

  Subsequently, the previous task search unit 11 searches for the previous task (secondary previous task) of “task 1” searched as the primary previous task, but the previous task name of the record whose task name is “task 1” is “ "NULL". As a result, the previous task search process (S003, S004) in the previous task search unit 11 ends, assuming that there is no previous task in “task 1” and no secondary previous task in “task 3”. .

  When the previous task search unit 11 finishes searching for the previous task related to the task selected in step S001 and storing the search result in the memory, the subsequent task search unit 12 selects the project management data 16 in step S001. The post-task is searched using the determined task as a base task, and the post-search task is stored in the memory (S006).

  When the post task is searched using the predetermined task selected in step S001 as a base task, the post task search unit 12 repeats the post task search process and searches the post task using the post task as a base task. After the search, the task is similarly stored in the memory (S006). The post-task search unit 12 repeats the search for the post-task and the storage of the search result in the memory until the post-task search is completed with all post-tasks to be searched as a base task (S005). The term “until the search for the subsequent task is completed” means that the searched previous task becomes “NULL”.

  For example, when the project management data 16 as shown in FIG. 3 is used, the post-task search unit 12 searches the task management data 16 for a task name associated with a predetermined previous task name, thereby determining the post-task of the task. Search for.

  Specifically, when “task 3” is selected as the predetermined task in step S001, the post-task search unit 12 selects a record in which “task 3” has the previous task name “task 3” in the project management data 16. In addition to extraction, “task 7”, which is the task name of the extracted record, is set as the primary post-task. In the example illustrated in FIG. 3, only the “task 7” is the task after “task 3”, but there may be a plurality of tasks after the task.

  Subsequently, a subsequent task (secondary post task) searched for as the primary post task is searched, and the task name of the record having the previous task name “task 7” is “NULL”. As a result, the post-task search process (S005, S006) in the post-task search unit 12 ends, assuming that there is no post-task in “task 7” and no secondary post-task in “task 3”. .

When the search of all previous tasks and subsequent tasks related to the task as the base point in steps S003 to S006 and storage of the search results in the memory are completed, the display control unit 13 associates the tasks stored in these memories. A display screen 200 including information and task attributes is generated (S007).
Thereafter, the display control unit 13 displays the display screen 200 generated in step S007 on the display device 105 (S008).

  FIG. 6 shows an example of the display screen 200 displayed in the task display process. The display screen 200 illustrated in FIG. 6 displays the dependency relationship of “task 3”. Specifically, the display screen 200 displays “task 1”, which is the previous task, and “task 7,” which is the subsequent task, linked to “task 3”. As shown in FIG. 6, the display screen 200 is not limited to the example including the resource name, the scheduled start date of the task, the scheduled end date of the task, etc. The dependency relationship or attribute of the selected task may be displayed in a pop-up or the like.

  As described above, according to the first embodiment of the present invention, the previous task and the subsequent task related to the specified task are searched and extracted, and the extracted previous task and the subsequent task are displayed in association with the task. . In addition, attributes related to each task are displayed at the same time.

  In this way, tasks having a dependency relationship with the designated task are displayed in time series, so that the project manager who is the process manager can easily grasp the relationship between the tasks. Specifically, by displaying the tasks related to the specified task instead of the dependencies of all tasks related to the project, the administrator can understand the dependencies of the task to be grasped at a glance. it can. Further, by displaying the task attribute information and the like such as the person in charge of each task and the scheduled execution date together with the dependency relationship of each task, the manager can easily manage the instructions to the person in charge.

  In addition, the person in charge can grasp the context of the task in charge and proceed with the work in cooperation with the person in charge of the previous and subsequent tasks. In addition, it is possible to improve the motivation for the execution of the project by grasping the position of the task in charge of the project in the project.

  Further, as shown in FIG. 3, the project management data includes a record that associates a predetermined task (task identifier) with a previous task (previous task identifier) of the predetermined task. The project management data shown in FIG. 3 does not associate the task specified by the previous task identifier with the task identifier specified by the task identifier. It can be understood as “task after task”. Therefore, it is possible to grasp the context of all tasks included in the project only by associating the previous task with the predetermined task without associating both the previous task and the subsequent task with the predetermined task.

  The task display device 1 according to the preferred embodiment of the present invention may be executed by one computer as shown in FIG. 1 or may be executed by a plurality of computers that can communicate with each other. For example, the task display device 1 may have a configuration in which the storage device 107 is provided outside or a configuration in which only a part of the data in the storage device 107 is provided outside.

  In the above description, the project plan is described as an object. However, the project that is the object of the task display device 1 according to the embodiment of the present invention broadly covers the object of the planning work, and is produced in addition to the project plan. All process management such as planning and operation planning are included. For this reason, the resource can be used not only for the person in charge of executing the task but also for a device that executes the task.

(Modification 1 of the first embodiment)
As a task display device according to the first modification of the first embodiment, project management data 16a in the format shown in FIG. 7 may be stored instead of the project management data 16 shown in FIG. The project management data 16a shown in FIG. 7 is an example of the project management data 16a in which a task attribute and a subsequent task name are associated with a task name. The task name, resource name, scheduled start date, scheduled end date, and subsequent task name are Has an associated record. The “post task name” identifies the post task. Since “task name”, “resource name”, “scheduled start date”, and “scheduled end date” are the same as those in FIG. The project management data 16a shown in FIG. 7 is associated with the “following task name” in place of the “previous task name” as compared with the project management data 16 shown in FIG. It is.

  In FIG. 7, “Task 1” indicates that the person in charge A starts on April 1, 2005 and ends on April 2, 2005. The post-task of “task 1” is “task 3”, and “task 3” indicates that “task 1” starts after “task 1” ends. In FIG. 7, “task 6” is scheduled to start on April 8, 2005 by the person in charge C and end on April 9, 2005. The subsequent task of “task 6” is “NULL”, which means that there is no subsequent task in “task 6”.

  When using the project management data 16a in which the task and the subsequent task of the task are associated as shown in FIG. 7, the previous task search unit 11 searches the project management data 16a for the task name associated with the subsequent task name. The previous task of a predetermined task is searched by. For example, when “task 3” is selected in step S001, the previous task search unit 11 extracts a record whose task name is “task 3” after the project management data 16a, and the task name of the extracted record. “Task 1” is the previous task.

  Further, the post-task search unit 12 searches the task management data 16a for a task before the predetermined task by searching for a task name associated with the predetermined post-task name. For example, when “task 3” is selected in step S001, a record whose task name is “task 3” in the project management data 16a is searched, and “task 7” which is a task name after the searched record is searched as a post task. And

  Also by the task display device according to the first modification of the first embodiment, the same effect as that of the task display device according to the first embodiment described above can be obtained.

(Modification 2 of the first embodiment)
As a task display device according to the second modification of the first embodiment, project management data 16b in the format shown in FIG. 8 may be stored instead of the project management data 16 shown in FIG. Specifically, project management data 16b shown in FIG. 8, dependent data having a record about the task dependencies shown in task data 16b ₁ and FIG. 8 (b) with a record relating to attributes of the tasks shown in FIG. 8 (a) 16b ₂ and the constructed. In the example shown in FIG. 8A, the task data 16b ₁ has a record in which a task name, resource name, scheduled start date, and scheduled end date are associated. In the example shown in FIG. 8B, the dependency data 16b ₂ has a record in which the task name is associated with the task name. The “task name”, “resource name”, “scheduled start date”, “scheduled end date”, and “subsequent task name” are the same as those in FIG. Further, the dependency relationship of the tasks related to the project stored in the project management data 16b shown in FIG. 8 is the same as the example shown in FIG.

When the project management data 16b shown in FIG. 8 is used, the pre-task search unit 11 extracts a record in which the task selected in step S001 is the post-task name of the dependency data 16b _{2 and} the task name of the extracted record Is the previous task.

The rear task searching unit 12, the task selected in step S001 extracts a the task name of the dependent data 16b ₂ records, the task name after the extracted record and latter task.

In the dependency data 16b ₂ shown in FIG. 8B, “task name” is associated with “following task name”. However, if “previous task name” is associated instead of “following task name”, the task is similarly performed. It is possible to grasp the dependency relationship.

  Also by the task display device according to the second modification of the first embodiment, the same effect as that of the task display device according to the first embodiment described above can be obtained.

(Second Embodiment)
Subsequently, a task display device according to a second embodiment of the present invention will be described. The task display device 1 according to the second embodiment is different from the task display device 1 described in the first embodiment in that a task related to a plurality of projects can be searched. Therefore, the project management data 16c stored in the storage device 107 of the task display device 1 according to the second embodiment includes a project name, task name, resource name, scheduled start date, scheduled end date, as shown in FIG. , And a record in which the previous project name and the previous task name are associated with each other. “Project name” identifies a project including a task as a work process. The “previous project name” identifies a project including the previous task as a work process. Since “task name”, “resource name”, “scheduled start date”, “scheduled end date”, and “previous project name” are the same as those in the first embodiment, description thereof will be omitted.

  In addition, since the configuration of the task display device according to the second embodiment is the same as that of the task display device described above in the first embodiment, description thereof is omitted.

  FIG. 9 shows that “task 3” of “project 1” is scheduled to start on April 6, 2005 by the person in charge C and finish on April 8, 2005. The previous task of “task 3” of “project 1” is “task 2” of “project 1”, and task 3 of project 1 starts after task 2 of project 1 ends. In FIG. 9, the project before “task 4” of “project 1” is “NULL”, the previous task is “NULL”, and “task 1” has no previous project and no previous task. Means. Thus, when the previous project and the previous task are “NULL”, the task has no previous task. Furthermore, in the example shown in FIG. 9, there are a plurality of records related to “task 6” of “project 1”. This means that “task 1” of “project 1” has a plurality of previous tasks. Show. In other words, it indicates that it is a requirement that a plurality of tasks be completed before executing “task 6” of “project 1”.

  When the project management data 16c as shown in FIG. 9 is used, the previous task search unit 11 extracts a record whose project name and task name are the project and task selected in step S001 from the project management data 16c. The extracted previous project name and previous task name are used as the previous project and previous task.

  Further, the post-task search unit 12 extracts a record in which the previous project name and the previous task name are the project and task selected in step S001 from the project management data 16c, and the project name and task included in the extracted record. Name the post-project and post-task.

  FIG. 10 is a Gantt chart that displays the project process plan indicated by the project management data 16c of FIG. In the Gantt chart shown in FIG. 10, time is represented in the horizontal direction, project and task types are represented in the vertical direction, and correlations between the tasks are represented using arrows. Each task name is associated with the name of the person in charge of the task as a resource name. The conventional Gantt chart shown in FIG. 10 includes all the tasks included in the target project. In order to understand the correlation between specific tasks, the user has to follow the previous and subsequent tasks. is necessary.

  FIG. 11 shows a flowchart for explaining display processing in the second embodiment. The flowchart shown in FIG. 11 is different from the flowchart shown in FIG. 5 in that the search process for the previous task in step S004 is changed to S104, and the post-task search process in step S006 is changed to S106.

  In the task display device according to the second embodiment, a project and task as a base point are selected (S001), and the reading unit 15 reads the project management data 16c (S002). Thereafter, in the previous task search process, the previous task search unit 11 also searches for the project to which the task belongs while referring to the project management data 16c. The retrieved project is stored in the memory as a previous project together with the previous task (S104).

  For example, a case where “task 7” of “project 2” is selected in step S001 using the project management data 16c shown in FIG. 9 will be described as an example. In this case, the previous task search unit 11 extracts a record having the project name “project 2” and the task name “task 7” from the project management data 16c, and uses the “previous project name” of the extracted record. A certain “project 1” is a primary previous project, and “previous task name” “task 4” is a primary previous task. Similarly, the previous task search unit 11 sets “project 1” and “task 5” as the primary previous project and the primary previous task.

  Subsequently, the previous task search unit 11 searches the previous project and the previous task based on “task 4” of “project 1”. Further, the previous task search unit 11 searches for the previous project and the previous task of “task 5” of “project 1”. However, in the project management data 16c shown in FIG. 9, there is no previous project and previous task of “task 4” of “project 1” and “task 5” of “project 1”, so “project 2” and “task 7 ”, the previous task search unit 11 ends the task search process (S003, S104).

  In the task display device according to the second embodiment, the post-task search unit 12 also searches for a project to which the task belongs while referring to the project management data 16c in the post-task search process. Further, the retrieved project is stored in the memory together with the post task as a post project (S106).

  For example, a case where “task 7” of “project 2” is selected in step S001 using the project management data 16c shown in FIG. 9 will be described. In this case, the post-task search unit 12 extracts a record in which the previous project name is “project 2” and the previous task name is “task 7” from the project management data 16c, and is the project name of the extracted record “ “Project 2” is the primary post-project, and “task 8” which is the task name of this record is the primary post-task. Further, the post-task search unit 12 also sets “task 10” of “project 3” as a task following “task 7” of “project 2”, and designates a primary post-project and a primary post-task.

  Subsequently, the post-task search unit 12 searches for “task 9” of “project 2” as the post-project (secondary post-project) and post-task (secondary post-task) of “task 8” of “project 2”. . Also, the post-project (secondary post-project) and post-task (secondary post-task) of “task 9” of “project 2” are not searched. Since the post-project and the post-task of “task 9” of “project 2” which is the secondary post-project and secondary post-task do not exist, the post-task search unit 12 performs the tertiary of “project 2” and “task 7”. The post-task search processing ends (S005, S106), assuming that there are no post-projects and tertiary post-tasks.

  Thereafter, the display control unit 13 generates a display screen by associating the previous project and the previous task, which are retrieved and stored in the memory, with the subsequent project and the subsequent task (S007), and displays the generated display screen on the display device 105. Displayed (S008).

  FIG. 12 shows an example of a display screen 200a displayed in the display process in the second embodiment. The display screen 200a illustrated in FIG. 7 displays the dependency relationship of “task 7” of “project 2”. Specifically, “task 4” and “task 5” as previous tasks are linked to “task 7”, and “task 8” and “task 9” as subsequent tasks are linked. The display screen 200a is not limited to an example including a task name, a resource name in charge of a task, a scheduled task start date, a scheduled task end date, and the like, as well as task dependency relationships, as shown in FIG. The dependency relationship or attribute of the task selected via 104 may be displayed in a pop-up or the like.

  In the project management data 16c described above with reference to FIG. 9, the “previous project name” and “previous task name” are associated with the project name and task name, but instead of the “previous project name” and “previous task name”, Even if “post project name” and “post task name” are associated with each other, it is possible to grasp the dependency relationship between tasks.

  As described above, according to the second embodiment of the present invention, the previous task and the subsequent task across a plurality of projects related to the specified predetermined task are searched and extracted, and the extracted previous task and the subsequent task are extracted. Display a task in association with a specified task. In addition, attributes for each task across multiple projects are also displayed. In this way, tasks that have a dependency relationship with the specified task are displayed in chronological order even when they span multiple projects, allowing the project administrator to manage multiple projects in a complex manner. However, it is possible to easily grasp the relationship between tasks across multiple projects. In addition, the person in charge can grasp the context of the task in charge over a plurality of projects and can coordinate with the person in charge of the previous and subsequent tasks, and can improve the motivation for executing the project.

  Further, as shown in FIG. 9, the project management data includes a record that associates a predetermined project (project identifier) and a predetermined task (task identifier) with a previous project (previous project identifier) and a previous task (previous task identifier). Have. As described above, the project management data shown in FIG. 9 does not relate the post-project and the post-task of the predetermined task. However, assuming that the project specified by the previous project identifier is “predetermined project” and the task specified by the previous task identifier is “predetermined task”, the project specified by the project identifier is “after the predetermined project”. The task specified by the task identifier can be grasped as “the task after the predetermined task”. Therefore, it is possible to grasp the context of all projects and tasks only by associating the previous project and the previous task without associating both the previous project and the subsequent task with the predetermined task.

(Modification of the second embodiment)
As a task display device according to a modification of the second embodiment, project management data 16d shown in FIG. 13 may be stored instead of the project management data 16c shown in FIG. Specifically, project management data 16d shown in FIG. 13, dependent data having a record about the task dependencies shown in task data 16d ₁ and FIG. 13 (b) with a record relating to attributes of the task shown in FIG. 13 (a) 16d ₂ and the constructed. The task data 16d ₁ shown in FIG. 13A has a record in which a project name, task name, resource name, scheduled start date, and scheduled end date are associated. The dependency data 16d ₂ shown in FIG. 13B has a project name, a task name, a previous project name, and a previous task name. Since “project name”, “task name”, “resource name”, “scheduled start date”, “scheduled end date”, “previous project name” and “previous task name” are the same as those in FIG. Description is omitted. Further, the dependency relation of the tasks related to the project stored in the project management data 16d shown in FIG. 13 is the same as the example shown in FIG.

When using the project management data 16b shown in FIG. 13, prior to the task retrieval unit 11, together with the selected task extracts records the task name of dependent data 16b ₂ at step S001, before the project name of the extracted record and The previous task name is the previous project and the previous task.

When the project management data 16b shown in FIG. 13 is used, the post-task search unit 12 extracts a record in which the task selected in step S001 is the previous task name of the dependency data 16b ₂ and the extracted record Let the project name and task name be the post-project and post-task.

In the dependency data 16d ₂ shown in FIG. 13, “previous project name” and “previous task name” are associated with the project name and task name, but instead of “previous project name” and “previous task name”, “ The task dependency can be grasped in the same manner by associating the “post project name” and the “post task name”.

  Also by the task display device according to the modification of the second embodiment, the same effect as that of the task display device according to the second embodiment described above can be obtained.

(Third embodiment)
Next, a task display device according to the third embodiment will be described.
FIG. 14 is a block diagram illustrating a task display device 1a according to the third embodiment. The task display device 1a according to the third embodiment is different from the task display device 1 according to the first embodiment described above with reference to FIG. 1 in that a search number setting unit 17 is provided. . The search count setting unit 17 limits the number of previous tasks searched by the previous task search unit 11 and the number of subsequent tasks searched by the subsequent task search unit 12. In other respects, the configuration of the task display device according to the third embodiment is the same as that of the task display device 1 described above in the first embodiment, and thus the description of each configuration is omitted.

FIG. 15 is a flowchart for explaining display processing in the task display device according to the third embodiment.
The flowchart shown in FIG. 15 differs from the flowchart shown in FIG. 6 in that step S003 is replaced with S203 and step S005 is replaced with S205.

  The search count setting unit 17 of the task display device 1a according to the third embodiment arbitrarily sets the search count when searching for the previous task when the previous task search unit 11 searches for the previous task. The search count setting unit 17 arbitrarily sets the search count when searching for a subsequent task when the post task search unit 12 searches for the post task. Here, it is possible to set different numbers for searching the previous task and the subsequent task. Further, the setting of the number of tasks to be searched is set by the user, for example, by an input via the input device 104.

  Therefore, the previous task search unit 11 repeats the previous task search process a specified number of times. For example, if the search count setting unit 17 is set to search for tasks up to three generations before (third previous task), the previous task search unit 11 searches for a task three generations before (third previous task). The previous task search process in step S004 ends.

  Further, the post-task search unit 12 repeats the post-task search process a specified number of times. For example, if the search count setting unit 17 is set to search up to a task after the fourth generation (fourth post task), the post task generation unit 12 searches for a task after the fourth generation (fourth post task). After step S006, the task search process ends.

  For example, a project may be carried out over several years. In such a large project, the number of tasks constituting the project is enormous. In the case of such an enormous project, even if a previous task several years ago is searched and extracted, it is considered that the task has already ended and several years have passed. However, information about the old previous task may be unnecessary. Therefore, the task display device according to the third embodiment can search and extract only a predetermined number of previous tasks and a predetermined number of subsequent tasks.

  In this way, by limiting the number of tasks to be extracted, in the case of a project formed by a huge number of tasks, only the most recent related pre- and post-tasks are searched, and far-related tasks are searched. It is possible to save time.

  As described above, the embodiments of the present invention have been described. However, it should not be understood that the descriptions and drawings constituting a part of this disclosure limit the present invention. From this disclosure, various alternative embodiments, examples, and operational techniques will be apparent to those skilled in the art.
