Abstract

PROBLEM TO BE SOLVED: To solve the problem that an effective method for finding problem points of the whole operation and finding the use of unnecessary information by using a workflow type information processing system is not available to a system designer and an administrator of the workflow type information processing system. SOLUTION: The workflow type information processing system detects information used when each of the processes constituting a workflow is executed and information needed to execute the processes by the processes, compares each piece of the information with information used by a final product as printed matter, screen display, and the execution results of other processes to decide the information used for the final product as value-added information, classifies other information as value-unadded information, and displays the information while relating it to the respective processes to make clear the use of unnecessary information, thereby improving the system and operations using it.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an analysis method and an analysis system for constructing a more efficient workflow in a workflow type information processing system.

[0002]

2. Description of the Related Art The purpose of an information processing system is to execute some work (workflow), and for that purpose, a complicated mechanism and a large amount of data are used. Evaluation of such a system has focused on how much the system has contributed to labor cost reduction and what services the system has provided. However, in reality, the introduction cost and the operation / maintenance management cost of the system are increasing due to the multifunctionality of the system. Building a more economical system is an urgent task.

[0003] On the other hand, a workflow constituting a business procedure is usually composed of several processing units. For example, in the case of a workflow system for settling a purchase request slip, "a drafter issues a purchase request slip"
Is one processing unit, and “the section manager settles and approves this” is also a processing unit. In the present specification, a unit of processing constituting such a workflow is hereinafter referred to as a “process”.

In a practical workflow type information processing system, the number of processes is extremely large. Therefore, in the development stage, the workflow is divided for each process, and the system development proceeds. Since many processes are developed, the same data item (eg, form ID number) is used in many processes. here,
“Use” corresponds to, for example, displaying and confirming the data item on the screen, or having the user input a specific value of the data item.

[0005] Such a divided system design / implementation causes a troublesome problem. That is, even if the workflow finally realizes a certain process, it is difficult to verify whether or not necessary and minimum processes are performed in order to realize the process. Specifically, (1) a data item for which it has been confirmed that there is no error in the data in the previous process is confirmed by the downstream process, although it is unnecessary, or (2) another data is confirmed in another process. Since the items have been checked, there is a problem that the input screen is designed and created as a process even though the data items are useless even if they are input. This is all a problem that could not be found because it was not known how to analyze the overall flow leading to the production of the final goal from the optimality of the overall workflow.

As a result, in the system design up to now, a request for displaying and inputting redundant data has been generated which has a negative effect on productivity in the system operation stage.

[0007] An example of a workflow and an analysis method using activity-based cost management, which is a conventional technique, will be introduced below. FIG. 3 shows an example of a workflow to be used. It is a submission paper management system (part) of the academic society. In FIG. 3, after the author submits the manuscript ((A) in FIG. 3), the secretariat of the society (operator) checks the manuscript (B), enters the manuscript data into the system (C), and sends the manuscript to the author. Create a postcard on which a “notification message” to report that the manuscript has been received is printed ((D), (E) in FIG. 3,
(F)), the secretariat of the society selects an editorial committee member in charge (H), and the nominated editorial committee selects one peer reviewer candidate from among the peer reviewer candidates retrieved from the field code of the dissertation. The society will be notified (I), and the secretariat of the society will finally decide on a peer reviewer (J). As a matter of course, the actual work of the secretariat of the academic society is more complicated, and processing occurs even after the workflow in FIG. 3, but is omitted in this specification.

Here, attention is paid to the printing of the "reception notice text" on a postcard. As shown in FIG. 4, the address and the name of the author are printed on the surface of the postcard. On the back side, the author's name, article number, and article title are printed as components of the receipt notice. A printer must be used to print the notification text. However, in this printer,
Printing of other documents is also performed. Therefore, when performing postcard printing, (1) declare that another operator will not perform printing, (2) change the printer paper, and (3)
When the printing is completed, the paper is returned to its original state, and (4) it is necessary to declare the completion of the operation to the surrounding operators.

The above-mentioned "change printer paper"
When operating the system, it is necessary to clearly consider the efficiency of the work that is inevitably occurring as a target for analyzing the entire business workflow and discuss the efficiency of the entire workflow.

As a conventional technique for improving the entire business flow, there is an activity-based costing which is a management accounting method.
This is a new cost calculation method that allocates management resources in detail and calculates product costs according to various activities in the product processing process. Traditional costing methods, such as the man-rate method, allocated production overhead to working hours. This traditional accounting method does not match the current manufacturing process, where indirect costs, such as machining time and design costs, are dominant. To solve this problem,
Developed and used is activity-based costing.

In activity-based costing, for example, in the machining process, costs are allocated in machine time, and the cost is allocated to design, setup, warehouse,
Support activities called material handling (article transportation)
Costs are paid for the number of times of design, setup, order, and transportation.

FIG. 6 is a diagram showing the principle of activity-based cost calculation. Management-related "resources" such as labor costs and factory premises
The first stage of allocating (60 in FIG. 6) to the “activity center” (61) and the “product” from the “activity center” (61)
(Cost calculation target: 62 in FIG. 6). Here, the activity center 61 is, for example, a department of a company or a function. In addition, multiple “cost pools” will be set up within the activity center to ensure accurate allocation. The cost pool is, for example, various detailed operations in a business unit. As described above, the activity-based cost management is characterized in that the costs are analyzed in multiple stages and the costs are analyzed in detail.

The standard for allocating resources from resources to the activity center is called “resource agent”, and the standard for allocating resources from the activity center to products is called “activity agent”. (Cost driver). " The cost driver indicates what management resources each activity center consumes. For example, if land and buildings are used as management resources, they will be allocated to the activity center in an occupied area. At this time, the occupied area is a resource factor.

On the other hand, for example, when the activity center is “Matehan (transportation)”, the number of bills issued to the material storage,
The number of processed transactions, the number of persons directly involved in the work, and the like serve as cost drivers, and for each product, the costs allocated to material handling are redistributed based on the cost drivers. However, the cost factor may not always depend on the operation rate. For example, design corresponds to this.

Activity-based cost management utilizes the concept of activity-based costing as a tool for restructuring business processes. The feature of activity-based cost management is that it distinguishes value-added activities that add value from non-value-added activities that do not, thereby revising whether each cost pool adds value to products, Review the entire business process. This activity-based cost management can be naturally applied to a workflow by setting a process constituting the workflow as an activity center.

The activity-based cost management is applied to the workflow shown in FIG. First, identify resources, activity centers, and products. Resources are the labor costs of the staff of the conference secretariat, and activity centers are the processes that make up the workflow. Products, on the other hand, are services to editors and authors.

In the first stage, labor costs are allocated to each activity center (= process). However, in accordance with the gist of activity-based cost control, non-value-added cost pools such as printer switching time and time to wait for the screen to start up, and value-added costs such as the time when the secretariat staff is actually making decisions. A pool will be provided for each activity center. Value pools are divided into value added and non-value added.

In the second stage, the cost of each activity center is allocated to products (such as services to authors of submitted papers). The non-value-added cost and value-added cost of the product are finally clarified. Specifically, as described below, for each process, the value-added time that is effectively used (= personnel cost) and the non-value-added time that is not used effectively (= personnel cost) are distributed. Granted. Furthermore, since it is clear in which process the non-added value was given, the problem part can be specified.

Specifically, for example, if there is a long software start-up time or a printer wait time for each process, the labor cost as a management resource on the basis of the time acting as a resource factor is: Allocated to each activity center (process). These are non-value added costs. on the other hand,
The time during which data is actually entered is allocated as value-added cost. In this way, the value-added cost and the non-value-added cost are calculated for each activity center (process). Therefore, if the costs of all the processes required by the final product are summed up, the value-added cost of the product is obtained. And non-value added costs. Thus, if it is considered that “activity center = process”, activity-based cost control can be naturally applied to workflow analysis. However, in this state, the conventional IE
(Industrial Engineering) does not differ greatly from the analysis method.

Also, in the first place, in the above-mentioned IE method, although it is known which process has a value-added time and a non-value-added time, a specific measure for how to improve it is selected. I can't. In other words, there is a problem in that even if there is a useless process, information on the design indicating that any data item is useless cannot be obtained.

[0036]

FIG. 1 is a diagram for explaining the principle of the present invention.

In the workflow analysis method 1 of the present invention (claim 1), when analyzing a workflow, a workflow holding step 11 for storing a workflow constituted by a chain of processes as a unit of processing of a program.
When,

In the workflow holding step 11, information used when each process is executed, and switching of printer paper and attachment of a label are not directly executed on a computer, but are required for the process. An information holding step 12 for storing a list of operations to be performed as information in association with each process;

A step of classifying the information stored in the information holding step 12 into value-added information reflected in the execution result and non-value-added information not directly reflected in the execution result. 13 and

A result display step 14 is provided for counting and displaying the number of value-added information and non-value-added information classified by the value-added information classifying step 13 for a plurality of processes along a series of flows. .

Here, in the workflow holding step 11, it is necessary to hold the names of the processes constituting the information processing system and the direction of the control flow between the processes. Specifically, this is a processing flow in which a form is passed between processes. These pieces of information may hold the process name as a process name list, for example. As for the direction of transition between processes, the name of the process that flows next may be stored for each process. This can be held by a tabular data structure, but other methods such as pointer information on a memory can be selected by those skilled in the art. How to remember
A person skilled in the art can freely select the present invention without directly affecting the gist of the present invention. For example, a specific implementation means is on a hard disk of a computer on which the analysis is performed.

Next, the information holding step 12 has a role of storing what information is used for each process held in the workflow holding step 11. Specifically, among the data items held on the database configuring the information processing system, in the process, the data item displayed and the data item obtained from the user are used as their names. An operation of storing the data corresponding to each process is executed. A process typically corresponds to a graphical user interface (GUI) screen that interacts with a user in a workflow information processing system. Therefore, specifically, this displayed data item,
The acquired data item is the data item itself to be displayed and requested to be input on the GUI screen.

However, as a feature of the present invention, the above GU
In addition to the data items on the I screen, the following characteristic information is collected and stored in the information holding step 12. That is, (1) when there is an output to the printer, the fact that the operator recognizes the printer is regarded as one data item is designated by the operator. It is assumed that the operator has received an instruction as one data item. That is, according to the gist of the present invention, in addition to the data items processed by the computer, various manual operations that occur with the execution of the process are also included in the information to be held. Specifically, in order to send a fax, it can be interpreted that a sheet is inserted or one operation instruction is given, and pressing a fax transmission button is also one operation instruction.

The above information is associated with each process,
It is necessary to hold the information in a memory or the like, and the information holding step 12 performs this holding process. In particular,
The data may be held by a table format tool, or pointer information on a memory may be used. How to store the data may be freely selected by those skilled in the art, and has no direct effect on the gist of the present invention. For example, a specific implementation means is on a hard disk of a computer on which the analysis is performed.

The added value information classifying step 13 classifies the information detected in the use information detecting step 12 into value added information and non-value added information, and holds the information.
However, here, a subset of the workflow composed of a plurality of continuous processes is converted into a final product (generally, some form stamping,
Alternatively, it is specified together with the final screen presented to the customer. Then, the information (data item or the like) output on the specified final product is added value information. On the other hand, information not included in the final product is defined as non-value-added information.

The value-added information described above may or may not appear on each process constituting a part of the workflow leading to the output of the final product. Some information (data items, etc.) used in each process but not included in the final product is treated as non-value-added information.

The role of the value-added information classifying step 13 is to divide the information of each process into value-added information and non-value-added information, for example, from the aforementioned viewpoint. However, the classification method shown here is only one example. The gist of the present invention merely claims that the step of classifying information based on some values exists here. For example, it is assumed that the final product is displayed not only on the GUI but also on the screen of the mobile phone at the same time. In this case, it cannot be evaluated as value-added information only from the viewpoint of appearing in the final product. This is because an item having an excessively large size cannot be displayed or takes a long time to display.
Data items that are present in the final product and that can be displayed with a certain number of characters or less can be value-added information having higher added value.

In the above processing, if some criterion for determining the added value is given and the final product is designated from the outside, it is stored in the information holding step 12 in correspondence with each process. Information (data items, etc.)
This can be easily realized by comparing with. The storage method may be freely selected by those skilled in the art, and does not directly affect the gist of the present invention.

The above result display step 14 finally determines what information (such as data items) as value-added information.
Are counted, and at the same time, what information (data items) and how many are present as non-value-added information is counted. This is displayed to the user of the analysis method. The user of the analysis method needs to recognize that if the non-value-added information is excessive compared to the value-added information, there is no waste in a series of processes. Also, as for the value-added information that appears many times, it is necessary to confirm whether or not it is a necessary appearance.

FIG. 2 is another diagram showing the principle of the present invention. In the workflow analysis system 2 of the present invention (claim 2), a workflow holding unit 21 that stores a workflow constituted by a chain of processes, which is a unit of processing of a program; Is not directly executed on the computer, such as information used when switching, printer paper switching, label attachment, etc., but a list of operations required in the process is associated with each process as information. Information storage means 22 for storing, and added value information classifying means 23 for classifying information stored in the information holding means 22 into value added information and non-value added information
And analysis means 24 for counting and displaying the number of value-added information and non-value-added information classified by the value-added information classifying means for a plurality of processes along a series of flows. . However, in FIG. 2, in the final product information 25, a data item name or the like on a form serving as a reference for distinguishing between added value and non-added value is input for analysis.

The second aspect of the present invention is a concrete implementation of the first aspect of the present invention as physical means. In this case, the physical means may be a circuit configured by an actual logic circuit, or may be a configuration realized as a program on a computer.

Further, the present invention of claim 3 provides the above-mentioned claim 1.
In the invention, the value-added information classifying method 13 is a step of, as print value or screen display, information added to the final product, which is an execution result of each process, as value-added information. But not using information used for production as non-value-added information.

Further, the present invention of claim 4 provides the above-mentioned claim 2.
In the invention, the added value information classifying means 23 includes information storage means for recording, as added value information, information added to the final product, which is an execution result in each process, such as a print result and a screen display, And information recording means for recording, as non-value-added information, information that is not added to the information but used for production.

Further, the present invention of claim 5 provides the above-mentioned claim 1.
And a storage medium storing a workflow analysis program using the workflow analysis method.

The present invention according to claim 6 provides the above-mentioned claim 3.
And a storage medium storing a workflow analysis program using the workflow analysis method.

Hereinafter, embodiments of the present invention will be described more specifically. The above-mentioned submitted paper management system (FIG. 3) will be described as an example. In Fig. 3, the author receives a manuscript reception notice postcard from the conference. "(G) Manuscript reception postcard reception"
Pay attention to. This is the "final product" for the author, the customer.

According to the gist of the present invention, first, the process name and the flow of the entire workflow are held by the workflow holding step (1 in FIG. 1) or the workflow holding means (21 in FIG. 2). In the example of FIG.
The entire workflow of FIG. 3 is retained.

Here, it is assumed that the “receipt notification message” postcard received by the paper author who is the customer is the evaluation criterion.
It is the "product" that postcards call in activity-based cost control. What activity center (= process) to produce this product
Think about what is involved. Related activity centers are:
In FIG. 3, there are three. "(D) Address label printing"
“(E) Print receipt notice” and “(F) Paste address label on postcard”.

The process is parted by attaching a label to the address of the postcard (government postcard) of the receipt notice,
On the other hand, on the message side, the fact that the paper has been received is printed, so that it cannot be realized by a single process. According to the gist of the present invention, it is necessary to analyze what data items are present in each process (see FIG. 4).
The information holding step (12 in FIG. 1) of the present invention or the information storage means (22 in FIG. 2) stores or holds these data items. Hereinafter, first, data items to be stored for each process will be described.

(D) Address Label Printing Process: In this process, the "article number", "address", "author name", and "label print position designation" are displayed or output (printed) by the system. The "article number" is entered by the operator as an ID number because it is necessary to instruct the system as to which paper is to be processed. The address is printed on a label as a postcard destination. The same applies to author names. However, the operator needs to instruct the system from which label position on the label sheet to print, and this is "label print position designation". Also, according to the gist of the present invention, replacement of printer paper is treated as one data item.

(E) Receiving Notification Text Printing Process: In this process, on the back of the postcard, “author name”, “article number”, and “article title” are written as correspondence messages, Imprint it inside and output. However, here, since it is necessary to turn over the postcard, the replacement of the printer paper is handled as one data item.

(F) Postcard address label attaching process: This is a very common operation. This is the work of peeling off the address label attached as a sticker from the label sheet and putting it on a postcard. The "article number", "address", "author name", "designation of label printing position", "article title", etc. used in the above three processes are stored in the information holding step (12 in FIG. 1) or the information storage means (FIG. In 22) of 2), the object is held and stored.

Next, the added value information classifying step (13 in FIG. 1) and the added value information classifying means (23 in FIG. 2) of the present invention.
Separates information in each process into value-added information and non-value-added information. Here, since the final product is a postcard on which the receipt notification text is printed, the non-value-added information in “(D) Address label printing” is “designation of label printing start position”. This information is necessary for label printing, but is not described in the final postcard. On the other hand, "address" and "author name" are added value information. Also, replacement of printer paper is non-value-added information.

Next, in the "(E) receipt notification text printing process", the "article title", "author name", and "article number" are printed on the postcard, so that they are added value information. However, in this case as well, it is necessary to switch the paper at the time of printing, so it is assumed that a paper switching instruction has been issued. Obviously, this is non-value-added information and needs to be returned after printing is complete, so there are two instructions. In the “(F) postcard address label printing” process, the peeling operation is registered as non-added value information, as a matter of course.

Finally, the result display step (14 in FIG. 1) of the present invention or the analyzing means (24 in FIG. 2) counts these value-added information and non-value-added information. This is equivalent to distributing the information used and printed by each activity center (= process) to the final product, thesis reception postcard. Figure 4 summarizes the allocation
Shown in The count result is as shown in FIG. However, the added value information is indicated by V, and the non-added value information is indicated by NV.

FIG. 4 shows what data items are printed on a postcard in what process. However, according to the gist of the present invention, information and operations, such as printer paper change, which are not programmed in actual computer processing, but are used in connection with the processing are treated in the same manner as data items. In FIG. 4, it can be seen that the data items described in the postcard, which is the final product, are classified as “value-added information”, and the other data items are classified as “non-value-added information”. You. An object of the present invention is to realize such a classification.

The following can be said from the analysis results of FIG.
One is that there is much non-value-added information. There are many data references that are not sent to the final customer, which is wasteful. In particular, there are many printer operations. Another is duplication of value-added information. The information printed on the postcard also has the same name.

In the workflow of FIG. 3, one reason for making address printing a separate process is that label printing requires replacement of printer paper and the like. Because it is. At a glance, it is easy to think that performing label printing in a lump to some extent reduces the labor of printing. However, from the above analysis results,
Batch processing itself that performs label printing collectively causes waste. You should stop batch processing. Also,
It is useless to print the name twice on a postcard to the user (author of the paper).

One improvement method to the above result is to prepare a postcard dedicated printer in order to eliminate the paper switching of the printer, and to stack the postcard for describing the destination and the message on only one side. Then, each time a dissertation is processed, the destination and the communication contents are printed on the same side without performing batch processing. As a result, the use of non-value-added information such as paper information exchange, label printing start position, paper information in the address label printing, paper author name, and duplicated added-value information is eliminated. Further, the process of attaching a postcard address label is also eliminated, and the processing time can be reduced and the productivity can be improved.

[0070]

As described above, according to the present invention, the duplication of the information given to the execution result in each process in the workflow type information processing system can be understood, the duplication of the value-added information can be eliminated, and the non-value-added information can be eliminated. It is possible to recommend information reduction. Furthermore, the analysis shows that it is possible to combine several independent processes into one.

In addition, it is possible to eliminate unnecessary use of information when designing the information processing system, thereby realizing a reduction in development cost.

Further, problems can be extracted from the operating system, and the problems can be utilized for improvement and system update.
