  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  The “examination work” in the present embodiment refers to, for example, examination of permit documents for buildings in local governments, etc., and examination of various application documents for residents at city halls.

  FIG. 1 shows a configuration of an examination work system including an examination work client terminal 10, an examination work server 20, and an examination work sub-function server 30 as an example of a work system.

  Each of the examination business client terminal 10, the examination business server 20, the examination business sub-function server 30, and the business function structure analysis terminal 40 includes an IF (11, 21, 31, 41) for communicating with the outside, and a CPU (12, 22, 32, 42), main memory (13, 23, 33, 43), and storage devices (16, 25, 35, 45), and the functions in the main memory are processed in the CPU. Each of the examination business client terminal 10 and the business function structure analysis terminal 40 includes an input device (18, 48) and a display device (19, 49).

  The IF 11 of the examination work client terminal 10, the IF 21 of the examination work server 20, and the IF 31 of the examination work sub-function server 30 are connected to each other via the network 9. Further, the IF 41 of the business function structure analysis terminal 40 is connected to the IF 11 of the examination business client terminal 10 via the network 8.

  The examination work client terminal 10 is a terminal for an operator (examination staff) 1 to operate an examination work system including the examination work client terminal 10, the examination work server 20, and the examination work sub-function server 30. The examination work client terminal 10 is paired with the examination work client function 14 that operates in combination with the examination work server function 24 of the examination work server 20 and the examination work sub-function server function 34 of the examination work sub-function server 30. The examination sub function client function 15 that operates is held in the main memory 13. When the operator (examination staff) 1 uses the auditing business client function 14 and the auditing business subfunction client function 15, the log input using the input device 18 and the auditing business client function 14 and the auditing business subfunction client function 15 are displayed. A log of the contents indicating the processing result of the screening work system to the operator (screening staff) 1 via the device 19 is stored in the input / output log 17 of the storage device 16.

  The examination work server function 24 of the examination work server 20 provides an operator (examination staff) 1 with an information processing function necessary for the examination work in cooperation with the examination work client function 14 of the examination work client terminal 10.

  The examination work sub-function server function 34 of the examination work sub-function server 30 cooperates with the examination work sub-function client function 15 of the examination work client terminal 10 to allow the operator (the examination staff) 1 to perform sub information processing necessary for the examination work. Provide functionality.

  The structure analysis function 44 of the business function structure analysis terminal 40 analyzes the processing structure of the entire system composed of the screening business client terminal 10, the screening business server 20, and the screening business sub-function server 30 (FIGS. 3 and 4). A structure (FIG. 7) obtained by dividing the above process into functional components is displayed as an analysis result.

  Here, the “functional component” refers to the overall function provided to the operator (examination staff) 1 by operating the system as shown in FIG. 4) Each divided part. For example, when the entire function is provided in the processing flow shown in FIG. 2, it is divided into “functional components” as shown by dotted lines in FIG. Each “functional component” provides a partial function to the operator (examination staff) 1 by performing a partial process.

  FIG. 2 shows the flow of processing when the operator (examination staff) 1 of the examination work client terminal 10 performs the examination work using the examination work client function 14 and the examination work sub-function client function 15 of the examination work client terminal 10. Show. The examination work client function 14 of the examination work client terminal 10 requests examination related information from the examination work server function 24 of the examination work server 20 based on the input to the input device 18 of the operator (screening staff) 1 (S100). The business server function 24 obtains examination-related information from the examination result 26 and responds to the examination business client function 14 of the examination business client terminal 10 (S101), and the response result received by the examination business client function 14 on the display device 19 in S101. Display (S102), and the operator (examination staff) 1 confirms the display contents.

  If the operator (examination staff) 1 confirms the display content and determines that additional information is necessary (YES in S103), the operator (examination staff) inputs an additional information request from the input device 18 of the examination business client terminal 10, and the examination business client The examination work sub-function client function 15 of the terminal 10 sends this request to the examination work sub-function server function 34 of the examination work sub-function server 30 (S104), and the examination work sub-function server function 34 of the examination work sub-function server 30 is added. Information is acquired from the sub-function history 36 and responds to the examination work sub-function client function 15 of the examination work client terminal 10 (S105), and the examination work sub-function client function 15 displays the response result on the display device 19 (S106). The operator (examination staff) 1 confirms this.

  In the case of NO in S103 or after S106, the operator (examination staff) 1 inputs to the input device 18 (S107). Thereafter, the processing flow in which the examination work client terminal 10, the examination work server 20, and the examination work sub-function server 30 cooperate with each other using the input to the input device 18 of the operator (screening staff) 1 continues.

  FIG. 3 shows the process flow of the structure analysis function 44 of the work function structure analysis terminal 40 when the process flow of the check work client terminal 10, the check work server 20, and the check work sub-function server 30 as shown in FIG. This is a processing flow in which the system is divided into functional components from the viewpoint of the business of the operator (business staff) 1 who uses the business system, and the divided results (functional component related diagram shown in FIG. 7) are displayed on the display device 49.

  The structure analysis function 44 is connected to the examination work client terminal 10 via the IF 41 and the network 8, acquires the input / output log 17 accumulated in the examination work client terminal 10, and stores it in the input / output log 46 of the storage device 45. (S201). As shown in FIG. 5, the input / output log 46 stored in S 201 is sent to the operator input history 102 input from the input device 18 by the operator (screening staff) 1 and to the operator (screening staff) output to the display device 19. Is a log of a user interface between the operator (examination staff) 1 and the examination work client terminal 10, which is composed of a pair of processing result displays 103.

  Note that the log acquired from the input / output log 17 in S201 may be a partial log in which conditions are limited to a specific period or a specific operator (examination staff) 1. Further, it may be collected from a plurality of different examination work client terminals 10.

  The structure analysis function 44 performs the process of S302, the business branch detection process S202-1 and the business merge detection process S202-2 shown in FIG. 4 (S202).

  The structural analysis function 44 obtains the functional component relation diagram shown in FIG. 7 from the record of the business branch detection process S202-1 created in S305 of FIG. 4 and the record of the business merge detection process S202-2 created in S309. It is created and displayed on the display device 49 (S203). Details of the process of S203 will be described below.

  In the first substep of S203, the result (131 and 133 in FIG. 6) of the business branch detection process S202-1 created in S305 is referred to, and the branch location (131 and 133 in FIG. 6) is defined as the functional component boundary. In addition, a business system functional component division structure (the ellipses of functional components 200, 201, and 202 in FIG. 7) is drawn, and in addition, a business system functional component related structure (from functional component 200 to functional component 201 and functional component in FIG. 7). Draw a branch arrow to 202). Drawing 7 is called a functional component relation diagram. Here, the record of the business branch detection process S202-1 created in S305 is the next operator input when the pattern extracted in S303 is two or more patterns, that is, after one processing result in the operator is shown. This is a case that differs depending on the case, that is, where there is a branch in the processing of the system from the viewpoint of operator work (131 and 133 in FIG. 6).

  In the second sub-step of S203, the result (132 and 133 in FIG. 6) of the business confluence detection process S202-2 created in S309 is referred to, and the confluence (132 and 133 in FIG. 6) is defined as the functional component boundary. A business system functional component division structure (the ellipses of functional components 200, 201, and 202 in FIG. 7) is drawn, and in addition, a business system functional component related structure (functional component 200 and functional component 201 to functional component in FIG. 7). Draw a merge arrow to 202). Drawing 7 is called a functional component relation diagram. Here, the record of the business merging detection process S202-2 created in S309 is a place where there are two or more patterns extracted in S307, that is, where there is a merging in system processing from the viewpoint of operator work (see FIG. 132 and 133 in 6).

  The structure analysis function 44 displays the processing result display & operator input pattern (131 lines, 132 lines,..., 133 lines,...) Of the display & input combination 47 in FIG. The usage frequency ("usage frequency" attached to the arrow in FIG. 7) is counted and displayed. For example, when there are 90 patterns in the display & input combination 47 in which the processing of the functional component 202 is performed after the processing of the functional component 200 (the content of 133 in FIG. 6) is shown in the example of FIG. "Use frequency 90" is displayed (S204).

FIG. 4 shows details of the functional component division processing S202 in the processing flow of the structural analysis function 44 shown in FIG. 3, and includes pre-processing S302, business branch detection processing S202-1 and business merge detection processing S202. -2. The process of FIG. 4 detects a business branch location or a business merge location as a functional component boundary. In other words, the business process while the business system does not perform the branch process and the merge process is extracted as a functional component. First, the pre-process S302 will be described. When the process of S202 is started (S301), the input / output log 46 of FIG. 5 acquired in S201 is referred to, and the process result display 103 (for example, “contents of S102” on line 111) to the operator of a certain business step, A combination of the operator input 102 (for example, the contents of “S104” on line 112) of the next business step is added to the display & input combination 47 shown in FIG. 6 (for example, line 131). This is performed for all the business steps of the input / output log 46 of FIG. 5, and the display & input combination 47 table of FIG. 6 is created (S302).

  Next, the business branch detection process S202-1 will be described. Attention is paid to the processing result display 122 = “contents of S102” to the operator in the first row (131) of the display & input combination 47 table of FIG. From all the lines of the display & input combination 47, a line in which the processing result display 122 = “contents of S102” to the operator is retrieved. In the example of FIG. 6, the 131st and 133rd lines correspond to the processing result display 122 = “contents of S102” for the operator, whereas the operator input 124 = “contents of S104” and “contents of S107”. A pattern is extracted (S303). If the number of patterns of the operator input 124 extracted in S303 is 1, the process proceeds to S306. If the number is 2 or more, the process proceeds to S305 (this example is 2 patterns, so the process proceeds to S305) (S304). If there are two or more patterns in S304, the corresponding patterns (131 and 133 in this example) in the display & input combination 47 are recorded (S305). The processing of S303, S304, and S305 is repeated for all the display & input combinations 47 while sequentially changing the processing result display 122 to the operator of interest in S303 to the next line (S306).

  Next, the business branch detection process S202-2 will be described. Attention is paid to the operator input 124 = “contents of S104” in the first row (131) of the display & input combination 47 table of FIG. From all the lines of the display & input combination 47, the line where the operator input 124 = “contents of S104” is retrieved. In the example of FIG. 6, only 131 lines are applicable, and one pattern of processing result display = “contents of S102” to the operator who is paired with the operator input 124 = “contents of S104” is extracted (S307). If the number of operator input patterns extracted in S307 is one, the process proceeds to S310. If the number is two or more, the process proceeds to S309 (this example is one pattern, so the process proceeds to S310) (S308). If there are two or more patterns in S308, the corresponding pattern of the display & input combination 47 is recorded (S309). The processes of S307, S308, and S309 are repeated for all the display & input combinations 47 while changing the operator input 124 noted in S307 to the next line in order (S310).

  FIG. 5 is an example of the input / output log 46 of the business function structure analysis terminal 40 having the same structure as the input / output log 17 of the examination business client terminal 10. When the operator (examination staff) 1 performs a series of operations as shown in FIG. 2 using the audit operation client terminal 10, the audit operation server 20, and the audit operation sub-function server 30, a plurality of operations are performed for one operation history ID 100. A line of the business step 101 is generated (for example, the first to fourth lines in FIG. 5). Records (rows) corresponding to each business step 101 include operator input 102 records that are input by the operator (examination staff) 1 to the examination business client terminal 10 using the input device 18 such as a keyboard and a mouse, and operator input. The processing result display 103 records for the operator are displayed on the operator (examination staff) 1 using the display device 19 such as a display. For example, 111 records are generated when S100 to S102 of the flow of FIG. 2 are processed. In FIG. 5, the input / output log 46 is composed of one table, but may be composed of another table for each business history ID 100.

  FIG. 6 is an example of the display & input combination 47 generated by the process of S302 of FIG. The business history ID 120, the business step 121, the processing result display 122 to the operator, the business step 123, and the operator input 124 are respectively the business history ID 100, the business step 101, the processing result display 103 to the operator, and the business step in the input / output log 46. 101 has the same meaning as the operator input 102.

  FIG. 7 is an example of a functional component relation diagram displayed on the display device 49 of the business function structure analysis terminal 40 created in the functional component relation diagram creation processing S203 of FIG. The example of FIG. 7 shows that the flow of the business system shown in FIG. 2 is divided into three functional components (200, 201, 202). The functional components are ordered and connected by arrows. Furthermore, a numerical value of the usage frequency is given to the arrow, and the numerical value of the usage frequency is counted and displayed in the usage frequency counting process S204 of the functional component relation diagram.

  FIG. 8 is an example in which after using FIG. 7, the usage frequency counting process S <b> 204 of the functional component relation diagram is performed on another display & input combination 47 to rewrite “usage frequency”. For example, when the system shown in FIG. 1 is operating in organization A and organization B, the business function structure is analyzed in each organization, and the structure and frequency of use are shown in FIG. It is displayed that the structure and frequency of use are as shown in FIG. In this case, in the organization A and the organization B, the functional component 200 → the functional component 202 is commonly used frequently, and in the organization A, processing via the functional component 201 is performed at a low usage frequency. It can be seen that the processing via the component 201 has never been performed. From this display, it can be displayed as shown in FIG. 8 that the functional component 201 is unnecessary in the organization B. As a result, for example, for an organization that uses the business system as shown in FIG. 8, it is possible to obtain an effect that it is understood that an inexpensive business system in which the function of the functional component 201 is reduced is more suitable.

  Further, even if the processing flow shown in FIG. 2 is not described in the system design document or the like, the functional component division shown in FIGS. 7 and 8 can be performed by this method. That is, it is possible with this method that it is impossible to perform business function structure analysis by humans.

  FIG. 9 is obtained by superimposing the division result (dotted line) obtained in the functional component division process S202 shown in FIGS. 3 and 4 on the flow of the process shown in FIG. The division result (dotted line) depicts the portion recorded by S305 of the business branch detection process S202-1 and S309 of the business merge detection process S202-2 as a boundary between the functional components.

  As shown in FIG. 9, “the effect of the invention” “dividing the processing flow of the business system into functional components from the viewpoint of the business of the operator who uses the business system” can be realized.
