Abstract

To solve the problem in which the introduction of the conventional task management program became difficult due to the high initial cost when introduction and a teaching cost since how a user progresses with work should match with the task management program, particularly, the high possibility of modification of the e-mail system that users use makes the introduction of the task management program.SOLUTION: Task management using e-mails is realized by collecting communications by e-mails of users with a mailing-list of the e-mail and organizing and storing the collected e-mails for each task without modification of the existing e-mail system and without modification of how to progress with the work by the conventional e-mail.SELECTED DRAWING: Figure 1

Description

  The present invention relates to a program for managing projects and tasks.

In recent years, in the field of work, the number of work and the amount of work have increased due to the shortage of workers and the sophistication of work, and the burden on workers has increased greatly. In particular, as the scope of work and the number of work increases, the number of tasks and deliverables that must be managed by each person (individuals and peers) is increasing. Work is also a big burden. As a result, there is an increasing need for project management / task management technology for efficiently managing tasks and deliverables, and the spread of the technology is gradually progressing at work sites.

In particular, systems and programs called task management tools, project management tools, groupware, and collaboration tools (hereinafter referred to as task management programs) have various functions and tools (e.g., Kanban and Gantt) that efficiently perform project management and task management. Schedule management and progress management by chart function, deliverable management such as files and documents, management of stakeholders such as stakeholders and players of projects and tasks, resource management of conference rooms and equipment, contact management of employees and related parties, projects And other tasks related to communication and unification, and sharing and management of the latest information related to projects and tasks, etc.), reducing the task management burden on users.

In addition, the task management program may prepare a task management Web page for each task so that information related to the task, such as task progress status, various data, and comments from task parties, may be referred to. Task personnel can access the task management web page and share and update information related to tasks, or communicate with other task personnel to improve the efficiency of information sharing and communication related to work. it can.

Advanced task management programs can manage the dependency between tasks. Task dependency is the relationship between whether a task requires the deliverables of another task and represents the priority of which tasks must be processed to complete that task (Hereinafter, a task that requires a product is called a request task, and a task that creates a product is called a preceding task). By managing the dependency relationship between the request task and the preceding task, the priority order between the tasks can be efficiently managed.

On the other hand, e-mail exists as a communication tool often used in work. An e-mail is a program or system that sends messages and data to a destination specified by an e-mail address, and is widely used in work as a means of communication with business people, like telephones and mail. In addition, since e-mail is a system widely used by various companies, even if a task management program is introduced in-house, many companies use e-mail when communicating with outside parties.

There are programs and systems (hereinafter referred to as mailing lists) called mailing lists, group mails, and distribution lists as programs utilizing electronic mail. The mailing list automatically sends an e-mail posted to a mailing list e-mail address (hereinafter referred to as an ML address) to an e-mail address registered as an e-mail address of an ML address distribution destination (hereinafter referred to as a distribution destination address). It is a system that distributes electronically and is an efficient system for exchanging e-mail with many users. In addition, since the distribution destination of the ML address is collectively managed by the mailing list, it is a system that can reduce mistakes in which a user mistakenly sends an email to a non-related person.

In addition, mailing lists include mailing lists having a task management program function such as a function for organizing and storing and managing mails sent to ML addresses, a schedule sharing, and a file sharing. Conversely, there are also task management programs that have a mailing list function. (Hereinafter, the mailing list with the mail storage function and the task management program are collectively called the task management program. The mailing list function of the task management program is also called the mailing list.)

In particular, some mail software for managing mailing lists and e-mails has a function for threading related mails. Threading refers to a function for associating a reply mail or related mail of the mail based on data included in the header portion of the mail. By using this threading feature, the mailing list can group sent emails into groups. As a commonly used threading, a mail having an In-Reply-To field is used as a reply mail, and an e-mail having the same ID as the ID in the In-Reply-To field of the reply mail is used as the original mail. (But not limited to).

In a company, employees belonging to an organization such as a department or an in-house group are collectively registered in an ML address of a mailing list, and information is expanded by sending an email to the ML address such as a notification to the entire department or a message to be communicated. Depending on the company, when a project team is formed, an ML address for the team is prepared for information development and sharing.

Also, in a conventional system, a task management program connected to an e-mail management system (or mail app) for sending and receiving and managing e-mails, when creating an e-mail, receiving an e-mail, or selecting an existing e-mail, There is also a task management program provided with a means for creating a new task based on the contents of an e-mail created, received or selected (see, for example, Patent Document 1).

In a conventional system, a message analysis service server for analyzing an e-mail message is added between a client PC and a mail transmission / reception service server that transmits / receives e-mail of the client PC, and the client PC transmits / receives the message. There is also a task management program including means for analyzing an e-mail by a message analysis service server and creating a new task and updating information of an existing task based on the result (see, for example, Patent Document 2).

JP 2010-049427 A JP2011-048532A

However, in order to introduce a conventional task management program, there has been a problem that it is necessary to drastically change the way the work has been done so far. Task management programs have efficient ways of working according to each program, but in order to adopt the task management program, it was necessary for the parties concerned to switch the way of working at once. As a result, initial costs such as learning costs for learning how to proceed with new jobs and costs for deteriorating work efficiency after the introduction will increase, and companies that place importance on continuous and stable execution of operations may introduce task management programs. It was getting harder.

In particular, when communication between workers is centered on e-mail, project management and task management methods using e-mail are often different for each working person. It was often difficult. Also, e-mail is used in various systems throughout the company, or is used for communication with other companies, so it may be necessary to use e-mail even when a task management program is introduced. In many cases, there were many cases that failed to improve the efficiency of task management by going back to the way of doing work centered on email.

Also, in the communication using the mailing list, there is an inconvenience that the distribution destination address is common for each ML address, so it is difficult to use the mailing list for task management for different tasks for each task.

In addition, since the conventional mailing list requires registration of the distribution address for creation and management of the ML address, it is difficult to manage the distribution address of the ML address with ease of sending an e-mail.

In addition, in a conventional task management program using electronic mail, a system or application is newly introduced into a client PC or mail application (see, for example, Patent Document 1), or electronic mail transmitted and received by the client PC is acquired and analyzed. Because there was a need to change the existing e-mail system, such as preparing a server or inserting a new message analysis service server between the client PC and the mail transmission / reception service server (for example, see Patent Document 2). The initial introduction cost was great. In addition, there was a high risk of business suspension due to mistakes when changing existing email systems.

In addition, the conventional task management program using e-mail has a problem that it does not have a means for collecting and organizing continuous e-mail exchange among all persons involved in the task. As a result, there is a problem that the effect of task management cannot be obtained unless the way of doing work performed by e-mail is changed to the way of working of the task management program. In particular, the conventional task management program using e-mail has only a function of collecting e-mail reply e-mails used when creating a task (see, for example, Patent Document 1). Even if it did, task data could not be corrected by intuitive operation. Some e-mail users create reply e-mails by looking only at the destination regardless of the contents of the original e-mail in order to save the trouble of describing the destination in a new e-mail. In a conventional task management program using electronic mail, such reply mail is also associated with the task as mail related to the task, which causes problems in task management.

Further, the conventional task management program has a problem that there is no simple access means from the email to the task data of the task management program. As a result, when a user who normally works by e-mail tries to access the task data of the task management program, it takes time to check and execute the access means, and the work efficiency has deteriorated.

The present invention works in a task management program without obstructing the communication between workers and the management method of each person conventionally performed by e-mail, and without changing the existing e-mail system that has already been introduced. The goal is to allow task management to be added to the exchange of email between people. In addition, even if the user is not aware of the task of the original mail / creates a reply mail by mistake, the purpose is to improve the task management by correcting the task data. .

In the present invention, in order to achieve the above object, the task management program is a program for causing a computer to realize the following functions.
A task management unit that stores task data that summarizes the distribution address and email data for each task.
When the e-mail addressed to the ML address is received, the mail processing unit that searches the task data to which the received mail belongs (hereinafter referred to as belonging task data) from the task data list in the task management unit, and performs the following (1) and (2) .
(1) If there is affiliation task data, the task data is set as affiliation task data of the received mail, the received mail is stored in the affiliation task data, and the received mail is transferred to the distribution address of the affiliation task data.
(2) If there is no affiliation task data, new task data is created as the affiliation task data of the received mail, and the sender / destination mail address of the received mail (mail addresses in the From, To, and Cc fields) Is stored in the distribution address list of the belonging task data, the received mail is stored in the belonging task data, and the received mail is forwarded to the distribution address of the belonging task data list.

In addition, as a method for searching for belonging task data, a method conventionally used for threading mail with a mailing list or mail software can be used. Specifically, the following (1) and (2) can be mentioned, but not limited thereto.
(1) A method in which task data for storing an e-mail having the same ID in the Message-ID field as the ID in the In-Reply-To field of the received mail is used as belonging task data.
(2) A method in which task data for storing an e-mail that can be determined to have the same subject as the subject field of the received mail is used as the assigned task data. If the subject is the same except for “Re:” or “Fw:”, or a character string automatically added or expected to be added by a task management program, mailing list, or mail software, Judge that the subject is the same. In addition, the difference between half-width and full-width characters and the type of character strings may be ignored.

As a result, users can register tasks, register related party email addresses, and emails related to tasks by simply adding the ML address to the email distribution destination address without significantly changing the way of working with email. Can be collected and organized.

In addition, since the user can introduce the task management program while continuing to use the existing e-mail system as it is, the risk of system change associated with the introduction of the task management program can be avoided.

In addition, since this program is also a task management program, information related to tasks using the functions and user interface of conventional task management programs as they are, such as management of task personnel, progress management, and related information (including e-mail) Can be managed.

In the present invention, it is possible to add, delete, move, and edit task data (distribution destination address, e-mail, predecessor task ID, request task ID, etc. described later) by the task management program. In the present invention, the task data of the received mail is determined by the mail stored in the task data. Therefore, by adding, deleting, moving, and editing the mail stored in the task data, the task data for storing the newly received mail is changed. Can be changed. For example (when the method of searching for affiliation task data is (1) above), a reply mail (referred to as mail B) of a certain mail (referred to as mail A) is newly received by moving to another task data. The reply mail of mail B (referred to as mail C) can be separated from the task data of mail A (mail C is stored in the task data stored in mail B).

As a result, when the user arranges the task data mails, the storage destination of the subsequent received mails can also be arranged. In addition, even if you reply to the wrong email, you can move the email saved in the wrong task data to the correct task data so that the subsequent received emails are saved in the correct task data. it can. Also, even if the user creates a reply mail without worrying about the task of the original mail, it is possible to save the subsequent reply mail in the correct task data by moving the mail to the appropriate task data it can.

In the present invention, task data for storing an e-mail having the same ID as the ID in the In-Reply-To field of the received mail in the Message-ID field and a subject different from the Subject field of the received mail (hereinafter referred to as request task). Data))
The mail processor
Create new task data and make it the belonging task data of the received mail,
Record the email address in the From, To, Cc field of the email in the distribution address of the belonging task data,
Forward the received mail to the distribution address and record the received mail in the belonging task data.
Furthermore, the requested task data is recorded in the assigned task data as a requested task,
Record the assigned task data in the requested task data as the preceding task,
Sometimes.

As a result, in order to create a new predecessor task, the user can execute a reply to the e-mail registered in the requested task by simply changing the subject and sending it.

In the present invention, the mail processing unit may prepare a unique task-specific ML address for each task data and describe the task-specific ML address in the From field of the forwarded mail. In this case, when the task-dedicated ML address is included in the destination of the received mail, the task data linked to the task-dedicated ML address is handled as belonging task data (note that the above-described belonging task data search and other methods Task data that has become affiliation task data in () may also be affiliation task data).

As a result, the user can efficiently manage the mail related to the task by managing the received mail with the task-dedicated ML address. Programs that handle e-mail such as e-mail software often handle distribution e-mail addresses specially in e-mail management and processing such as search and filtering, so users should process received e-mails efficiently. Can do. Further, the user can save the mail in the task management program as mail related to the plurality of tasks by adding a plurality of task-specific ML addresses to the distribution destination address.

In the present invention, when the received mail is transferred, the mail processing unit may add the URL of the task management Web page to the mail body, the mail subject, or the display name of the ML address. For example, you can add the sentence “This task can be referenced at https: // ●●●” at the beginning of the email body, or the sentence “(https: // ●●●)” at the end of the email subject. It may be added or the From field of the forwarded mail may be “https: // ●●● <ML address>” (https: /// ●●● is the URL for task management), but this is not limited.

As a result, the user can easily access the task management page simply by accessing the URL in the received transfer mail. In particular, some mail applications have a function of interpreting a URL in a mail text as a link to a Web page and automatically displaying the Web page of the URL by a browser when the URL is clicked. When such a mail application is used, the task management Web page can be referred to simply by clicking the URL of the task management Web page. A task management Web page can be accessed.

Some mail applications may embed the subject or From field of the original mail in the mail body as a quote mail in the reply mail or forwarded mail. Since the URL of the task management Web page is embedded in the mail body in the reply mail of such a mail application, not only the forward mail according to the present invention but also the reply mail and forward mail by other mail applications Since the URL of the task management Web page is embedded in the mail body, the task management Web page can be easily accessed.

In addition, since many email applications display the subject of received emails in a list, adding the URL of the task management Web page to the subject increases the opportunity for the user to see the URL of the task management Web page. The chance to access the task management Web page can be increased.

In the present invention, the task management Web page may be accessed only by a user having an e-mail address registered as a distribution destination address in task data.

As a method for authenticating a user of an e-mail address, a method conventionally performed by a task management program or a net service can be used. Examples include (but are not limited to) the following means. For example, user authentication means (password, biometric authentication, etc.) associated with an email address in advance is registered in the task management program, and the user authentication means is passed to the user before accessing the task management page. Alternatively, when the user accesses the task management Web page, an authentication mail is sent to the mail address, and the user of the mail address is made to execute the user authentication procedure. Such.

As a result, the task management Web page can be accessed only by members exchanging emails, so that the risk that members not related to the task obtain information on the task can be reduced.

In the present invention, when a file is attached to the received mail, the mail processing unit may delete the attached file from the forwarded mail.

As a result, the file size of the forwarded mail can be reduced in the present invention. Some e-mail programs limit the file size limit of attached files. Even when a mail is sent to the other party using such an e-mail program, the file can be sent in the same procedure as the conventional e-mail sending. Since the attached file is saved in the task data together with the mail, it can be obtained by accessing the task management page. By using the additional task management URL, the recipient of the forwarded mail can easily access the task management page and obtain the attached file.

In the present invention, when new task data is created, the mail address in the From field of the received mail is set as the task owner, the mail address in the To field is set as the task executor, and the mail address in the Cc field is set. A role may be assigned as a task referencer.

As a result, the user can register the role of the task with less effort when creating a new task by e-mail.

In the present invention, in addition to the conventional task management program, a task management function using e-mail communication as it is can be added. A task management program can be introduced at low cost. In addition, even if the user is not aware of the task of the original mail / creates a reply mail by mistake, moving the mail stored in the task data and modifying it, the subsequent received mail is correct task data Therefore, task management can be improved without changing the user's mail exchange.

Configuration diagram of a program showing an embodiment of the present invention The block diagram which shows the task data of embodiment of this invention

Hereinafter, embodiments embodying the present invention will be described.

FIG. 1 is a diagram illustrating a configuration of a task management program according to the embodiment. This embodiment includes a mail transmission / reception unit 101, a mail processing unit 111, a task management unit 112, and a task management page display unit 114. The task management unit 112 includes zero or more task data 113.

FIG. 2 is a diagram illustrating a configuration of the task data 113 according to the embodiment. The task data 113 includes a task ID 211, a preceding task list 221, a requested task list 231, a distribution destination address list 241, and a mail list 251. The preceding task list 221 includes zero or more preceding task IDs 222, the requested task list 231 includes zero or more requested task IDs 232, the distribution destination address list 241 includes zero or more distribution destination addresses 242, and the mail list 251. Includes zero or more mails 252.

The mail transmission / reception unit 101 is connected to a network and transmits / receives mail. When the mail transmitting / receiving unit 101 receives the mail, the mail transmitting / receiving unit 101 transmits the mail as the received mail 121 to the mail processing unit 111.

When the mail processing unit 111 receives the received mail 121 from the mail transmitting / receiving unit 101, the mail processing unit 111 searches for task data to which the task data of the received mail 121 belongs. Specifically, the following (1), (2) and (3) are performed.

(1) The mail 252 having the same ID in the Message-ID field as the ID in the In-Reply-To field of the received mail 121 is found as the original mail, and the task data 113 to which the original mail belongs is set as the assigned task data.

(2) From each mail 252 recorded in each task data 113 of the task management unit 112, a mail that can be determined to have the same subject as the subject of the received mail 121 is found as the original mail, and the task data 113 to which the original mail belongs belongs to Data. If the subject is the same except for “Re:” or “Fw:”, or a character string that is automatically added or expected to be added by a task management program, mailing list, or mail software, Judge that the subject is the same. In addition, it ignores the difference of half-width and full-width characters and the difference of typographic characters as much as possible and judges that the subject is the same.

(3) When the task ID 211 is included in a part of the transmission destination address of the received mail 121, the task data 113 corresponding to the task ID 211 is set as the belonging task data.

When the mail processing unit 111 finds the belonging task data in the above (1), (2), and (3), it stores the received mail 121 in the mail list 251 of the belonging task data and stores it in the distribution destination address list 241 of the belonging task data. A transfer mail 122 having a distribution address 242 as a destination is created, and the transfer mail 122 is transmitted to the mail transmitting / receiving unit 101.

When the mail processing unit 111 finds the assigned task data in (1) and the subject of the original mail and the subject of the received mail 121 are different, the mail processing unit 111 assigns a new task ID 211 that is not used by other task data. Then, task data 113 having the task ID 211 is newly created, and the newly created task data 113 is set as belonging task data. Then, the sender / destination mail address (the mail address in the From, To, and Cc fields) of the received mail 121 is recorded in the distribution address list 241 of the assigned task data. Then, the received mail 121 is stored in the mail list 251 of the newly created affiliation task data, the transfer mail 122 is created with the distribution destination address 242 in the distribution address list 241 of the affiliation task data as a destination, and a mail transmission / reception unit A forwarding mail 122 is transmitted to 101. Further, the task ID of the task data to which the original mail belongs is added as a request task 232 to the requested task list 231 of the task data 113, and the assigned task data (task data 113) is added to the preceding task list of the task data to which the original mail belongs. Task ID 211 is added as a preceding task ID.

When the mail processing unit 111 cannot find the assigned task data in the above (1), (2), and (3), the task processing unit 211 newly assigns a task ID 211 that is not used by other task data, and has the task ID 211. 113 is newly created, and the newly created task data 113 is set as belonging task data. Then, the sender / destination mail address (the mail address in the From, To, and Cc fields) of the received mail 121 is recorded in the distribution address list 241 of the assigned task data. Then, the received mail 121 is stored in the mail list 251 of the newly created affiliation task data, the transfer mail 122 is created with the distribution destination address 242 in the distribution address list 241 of the affiliation task data as a destination, and a mail transmission / reception unit A forwarding mail 122 is transmitted to 101.

In addition, when storing the mail address in the distribution destination address list 241 in the above, the mail address in the From field is the owner of the belonging task data, the mail address in the To field is the executing person of the belonging task data, and the mail address in the Cc field. Is recorded as a reference to the assigned task data.

The From field and subject of the forwarded mail 122 describe the task-specific ML address created from the task ID 211 and the URL of the task management page, and the top of the email body of the forwarded mail 122 contains the task management page created from the task ID 211. Add a URL. Specifically, “https: // ●●●” is described in the From field, “(https: // ●●●)” is added to the end of the sentence in the Subject field, and the beginning of the mail text Add the sentence “This task can be referenced at https: // ●●●”. (Https: // ●●● is the URL of the task management page, and OO is the task-dedicated ML address).

In addition, when the received mail 121 includes an attached file, the forwarded mail 122 does not include the attached file, and a sentence “attached file saved in task management page” is added to the head of the mail body.

In the present embodiment, it is possible to switch whether to transmit the forwarding mail 122 including the transmission source address and the transmission destination address of the received mail 121 by the setting of the mail processing unit 111.

When the mail transmission / reception unit 101 receives the transfer mail 122 from the mail processing unit 111, the mail transmission / reception unit 101 transmits the transfer mail 122 to the network.

The task management page display unit 114 is connected to the network, and displays and manages a task management Web page. When the task management page display unit 114 receives a request for the URL of the task management page, the task management page display unit 114 returns HTML data for displaying the task management page corresponding to the URL to the request source. This HTML can use task management HTML data used in a conventional task management program. Using this task management page, the user can manage tasks in the same way as a conventional task management program.

Further, the user can edit the data of the task data from this task management page. Specifically, it is possible to add, delete, move, and edit task data distribution destination addresses, emails, preceding task IDs, and requested task IDs.

In this task management page, user authentication for identifying a user corresponding to the distribution destination address 242 registered in the distribution destination address list 241 is prepared. Unless the user authentication is passed, the task management is performed. I can't access the page. For this user authentication, a user authentication system used in a conventional task management program or a net service can be used. In this embodiment, the following (1) and (2) are obtained.

(1) Register user authentication means (password, biometric authentication, etc.) associated with an email address in advance in the task management program, and allow the user to pass the user authentication means before accessing the task management page.

(2) If the e-mail address is not registered in the task management program, an authentication e-mail is sent to the e-mail address, and the e-mail address owner is made to execute a user registration procedure.

As described above, according to the present embodiment, in the task management program, project management is performed during the exchange of e-mails without obstructing the communication between workers and the management method of each person, which has been conventionally performed by e-mail.・ It becomes possible to introduce task management. Further, according to the present embodiment, the mailing list and the ML address can be used for management for each task by easily registering the mailing list ML address and the distribution destination address by using the e-mail. . In addition, even if the user is not aware of the task of the original mail / creates a reply mail by mistake, moving the mail stored in the task data and correcting it, the subsequent received mail is correct task data Therefore, task management can be improved without changing the user's mail exchange.
