Embodiment 1 FIG.
The present embodiment is a system for the purpose of improving the quality of documents related to software development products. The document includes specifications and design documents, but any other document type may be used as long as it is related to software development / use.

  Each document is changed in version (version) at the timing of correction (revision). Document versioning is done by edition, and the newer the edition, the newer the content of the document. Each document is divided by section (chapter or section).

  FIG. 1 is a system configuration diagram according to the present embodiment. A hardware configuration not included in FIG. 1 will be described later with reference to FIG. A document creator uses the creation terminal 100 to create and modify a new document. The document reviewer uses the review terminal 200 to review the document. The analysis server 300 is a server that performs analysis on document quality, and is connected to the creation terminal 100 and the peer review terminal 200 via the network 400. In the analysis server system 500 including the creation terminal 100, the review terminal 200, and the analysis server 300, a plurality of creation terminals 100 and review terminals 200 can be configured. When the creation terminal 100 and the peer review terminal 200 are configured as a pair with a creator or a reviewer, the number of terminals can be set in accordance with the number of persons. Further, the creation terminal 100 and the peer review terminal 200 can be configured as one terminal. In that case, the creator can serve as a reviewer of another document on one terminal.

  The creation terminal 100 accepts input relating to a document displayed on the display unit 11, display unit 11 configuring data to be displayed on the display device, print unit 12 configuring data to be printed on the printing device (printer), The document creation means 13 which comprises document data, and the communication means 14 which transmits / receives data via the network 400 with the peer review terminal 200 or the analysis server 300 are provided. The printing unit 12 appropriately prints a document using a printing apparatus.

  The peer review terminal 200 comprises display means 21 that constitutes data to be displayed on the display device, peer review processing means 22 that accepts input of peer review results, and data that is to be printed on a printing device (printer). And a communication unit 24 that transmits / receives data to / from the creation terminal 100 and the analysis server 300 via the network 400. The printing unit 23 prints a document and a review result as appropriate using a printing apparatus.

  The analysis server 300 stores the document information (first document information) received from the creation terminal 100 that is the latest document information, the communication means 31 that transmits / receives data to / from the creation terminal 100 or the peer review terminal 200 via the network 400. The difference from the document information (second document information) contained in the document file 36 stored in the apparatus is recorded as a difference information file 38, and the document information (first document information) received from the creation terminal 100 is recorded as a document. Recording means 32 that records as a review information file 37, which is recorded as a file (second document file) 36, and further receives peer review information received from the peer review terminal 200, and display means that constitutes data to be displayed on the display device 33.

The recording unit 32 compares the document information (second document information) included in the document file 36 with the number of characters added or deleted with the document information (first document information) received from the creation terminal 100. Then, at least one of the changed number of characters is recorded in the difference information file 38 as difference information.
As for the document file 36 and the difference information file 38 recorded by the recording means 32, a new version (version) is created at the timing of revision (revision) of the document. The version name is included as part of the file name.

  Among the difference information files 38, the first difference information file 38 includes the document information (first document information) received from the creation terminal 100, which is the latest document information, and the document file 36 stored in the storage device. The recording unit 32 stores the document information (first document information) received from the creation terminal 100, which is the latest document information, in the document file 36. Before overwriting, the difference between the two pieces of information is calculated, and the first difference information file 38 is created. Similarly, the second difference information file 38 receives the document information of the previous version from the creation terminal 100, and before overwriting the document file 36, the two pieces of information (the first version of the first version). A file created by the recording means 32 by calculating the difference between the document information and the second document information of the document file 36 when the first document information of the previous version is received. The third difference information file and the fourth difference information file are also created at the same timing. In addition, each difference information file 38 manages the version by the file name.

  For example, the file names are given as “sabun01”, “sabun02”,... If the name is “sabunxxx” and the “xxx” part is a sequential number, the file with the highest file name becomes the first new differential information file, and the file number with the next highest number The second difference information file is the second newest difference information file, and the file with the next largest file name is the third third difference information file, which is associated in this order.

  Further, the analysis server 300 associates the document file 36, the peer review information file 37, and the difference information file 38, and refers to the difference information file 38 based on a request from the file management unit 34 and the creation terminal 100 that manages in one folder. Thus, an analysis unit 35 for calculating the quality analysis result of the document is provided. By the management of the file management means 34, the document file 36, the peer review information file 37, and one or more difference information files 38 of the same document are stored in the same folder.

  The analysis unit 35 stores the analysis result in the analysis file 39. The file management means 34 refers to the review condition file 40 to associate the creator and the reviewer with the document, and manages the transmission and reception of data to the creator and the reviewer corresponding to the document (folder). To do.

  The analysis unit 35 performs quality analysis on the document file 36, and the processing will be described later with reference to FIGS. In order to display the analysis result shown in FIG. 10, the analysis means 35 calculates a numerical value obtained by dividing the correction amount for each section by the description amount as the correction rate for each section, and further calculates the average value or the center of the correction rates for all sections. A value is calculated, an upper limit and a lower limit of the target range with respect to the average value or the median value are set from the target range including the upper limit value and lower limit value of the predetermined target range value, and the information is stored in the analysis file 39 . If there is a section with a correction rate not included in the range from the upper limit to the lower limit of the target range, that section is recorded in the analysis file 39 as a warning target.

  Further, in order to display the analysis result shown in FIG. 11, the analysis unit 35 takes out the difference information file 38 and stores the correction amount stored in the first difference information file 38 in the second difference information file 38. The correction amount is divided and calculated as a correction fluctuation rate, and the correction amount for the second document information is multiplied by the correction fluctuation rate to calculate a correction amount prediction value at the next correction. Such information is stored in the analysis file 39. Further, using the information of the description amount after change stored in the difference information file 38, the analysis unit 35 uses the post-change information stored in the difference information file (first difference information file) 38 to a predetermined convergence value. The target value is calculated by multiplying the description amount, and this target value is recorded in the analysis file 39.

In order to display the analysis result shown in FIG. 12, the analysis unit 35 refers to the project information DB 41, extracts the latest difference information file 38 of the document related to the program included in the same project, and describes the changed description amount. Is added. Further, the development amount included in the same project is added from the project information DB 41, and the changed description amount and the development amount are stored in the analysis file 39. A regression line is calculated by regression analysis, and a predetermined target range (a constant amount related to the description amount) is used as graph data. The calculated information is recorded in the analysis file 39 . The target range may be a fixed percentage of the description amount.

  Next, files stored in the analysis server 300 will be described. The document file 36 is a file that stores document information, and is always overwritten and stored with the latest information. Any format can be used as long as it can be created / modified using application software or the like on the creation terminal 100 and the peer review terminal 200, such as a text format, a Word format, and an Excel format.

  The difference information file 38 is a file that stores the difference by comparing the document information included in the pre-change file stored in the document file 36 with the changed document information received from the creation terminal 100. The difference information file 38 is created corresponding to the change timing of the document file 36.

  FIG. 13 is a diagram showing an example of the difference information file 38. The amount of description before change (number of characters), the amount of description after change (number of characters), and the amount of correction for each section (classification by chapter division) are stored. The pre-change description amount (number of characters) is the number of characters in the state before the change of the document file 36 (document pre-change file), and the pre-change description amount (number of characters) is the state of the document file 36 after change (document number). This is the number of characters in the modified file. The number of characters is counted by the recording means 32 using an existing character counting technique. The amount of correction was calculated from the number of added characters, the number of deleted characters, and the number of changed characters by comparing the document information contained in the pre-change file with the document information contained in the post-change file. Is.

  For example, the number of added characters, the number of deleted characters, and the number of changed characters may be added as the correction amount, or the number of added characters and the changed number of characters may be set as the correction amount.

  The review information file 37 is a file that stores review information from reviewers and correction information from creators. Program information, document name, and review information (review date, reviewer affiliation, name, reviewer) Comments, etc.), information related to corrections (such as the creator's response date, creator's affiliation, name, correspondence details (commented, comments from reviewers, etc.), etc.). It is updated at the timing when peer review information is received from the creation terminal 100 and the peer review terminal 200.

  The analysis file 39 stores the results analyzed by the analysis means 35. Since it is a file for providing the analysis result to the creation terminal 100 or the peer review terminal 200, the information may be updated each time the analysis is performed, or the analysis result may be accumulated.

The review condition file 40 is a file for associating a creator with a reviewer for one document. The configuration of the peer review condition file 40 is illustrated in FIG. As shown in FIG. 14, the review condition file 40 stores at least one mail address of the creator and the creator and one of the reviewer and the reviewer for each program name and document name. That is, it is possible to designate a plurality of creators and a plurality of reviewers for one document.
The file management means 34 refers to the review condition file 40 to confirm the creator and reviewer for the created document, and sends the corresponding document file 36 and review information file 37 to the creation terminal 100 and the review terminal 200. To do.

  The configuration of the project information DB 41 is illustrated in FIG. It may exist in another server that performs management related to software, and may be configured to acquire data at a certain timing. The project information DB 41 includes information on a project group, a program name, and a development amount (KL (kilo line) or FP (calculated by the function point method)) into which the programs are classified.

  Next, a folder configuration example and a screen display example will be described with reference to FIG. In the analysis server 300, the file management unit 34 associates the document file 36, the peer review information file 37, and one or more difference information files 38, and manages them in one folder. As illustrated in FIG. 2, the document file A, the peer review information file A, the difference information file A1, the difference information file A2, and the difference information file A3 are files related to the same document (document file A). Managed. Similarly, the document file B, the peer review information file B, the difference information file B1, the difference information file B2, the difference information file B3, and the difference information file B4 are files related to the same document (document file B), and therefore are stored in the same folder. Managed.

  In the difference information files A1 to A3, the difference information file A3 is the first difference information file (which stores the difference between the latest version and the previous version), and the difference information file A2 is the second difference file. It is an information file (which stores the difference between the latest previous version and the latest two previous versions), and the difference information file A1 is the third difference information file (the latest two previous versions and (The difference between the latest three previous versions is stored). In order to associate with the program, the folder name includes the program name and the document name, and the document name and the difference information file name include the version name.

In the creation terminal 100, the selection screen 15 and the analysis screen 16 are displayed by the display means 11 and the document creation means 13. As displayed on the selection screen 15, documents A, B, and C already exist as documents related to the creator. When the user corrects the document, it can be corrected by pressing the “correct” button. . The communication means 14 receives the document file 36 and the peer review information file 37 from the analysis server 300 at the timing when the “correct” button is pressed. The display means 11 and the document creation means 13 accept the input of the correction of the document and the input of the review reflection information. Although not shown, the creator performs the “overwrite saving” process of the document using the corresponding application. The document creation means 13 detects the detected timing, and transmits document change information and peer review reflection information to the analysis server 300.
Note that an “update” button is provided on the selection screen 15, and the document file 36 and the peer review information file 37 temporarily stored in the creation terminal 15 are stored in the analysis server 300 when the creator presses the “update” button. You may comprise so that it may transmit.

  When the user creates a new document, new document information can be created by pressing the “New” button. In addition, a creator who has a deletion authority can delete a corresponding document by pressing a “delete” button.

  The analysis screen 16 is a screen in which the quality analysis result of the document is displayed in a graph. When the user presses the “analysis” button, an analysis is requested from the display unit 11 to the analysis server 300 and the result is displayed. . An analysis result concerning another document can be displayed by a “switch” button. Further, different analysis results regarding the document A can be displayed by the buttons of “Display 1” to “Display 3”.

In the peer review terminal 200, the selection screen 25 and the analysis screen 26 are displayed by the display means 21 and the peer review processing means 22. As displayed on the selection screen 25, the review of the documents A, B, and C associated with the reviewer is awaiting processing. When the reviewer presses the “Review” button, the communication means 24 of the review terminal 200 requests and receives the corresponding document file 36 and the review information file 37 from the analysis server 300. The reviewer overwrites the review information file 37 with the review result using the corresponding application. When the reviewer presses the “notify” button, a review information file 37 overwritten with the review result of the reviewer is returned to the analysis server 300. The peer review terminal 200 can also request quality analysis. When the user presses the “analysis” button, the display means 21 requests the analysis server 300 for analysis, as in the analysis screen 26. Display the results. The configuration of the analysis screen 26 is the same as that of the analysis screen 16.
Since the document file 36 and the review information file 37 received from the analysis server 300 are temporarily stored only during the review process, the document file 36 and the review information file 37 may be deleted from the storage device after the process.

Next, the flow of processing will be described with reference to FIGS. 3 to 4 are flowcharts showing the flow of processing relating to document creation / modification. When the file management means 34 of the analysis server 300 detects that the peer review information is input to any peer review information file 37, the peer review condition file 40 is referred to the creator corresponding to the relevant peer review information file 37. Processing is started by requesting confirmation of peer review. As a confirmation requesting method, the selection screen 15 shown in FIG. 2 can be displayed by sending a mail to be requested and describing the address to the Web page dedicated to the creator in the mail.
Alternatively, a web page dedicated to the creator may be prepared and the creator may start processing at an arbitrary timing by connecting to the address.

  The processing is started, and the display means 11 and the document creation means 13 of the creation terminal 100 accept input of new creation or modification of the document from the creator through the selection screen 15 (step S1). The creation means 13 requests the latest document file 36 and the peer review information file 37 from the analysis server 300 via the communication means 14, and receives two files via the communication means 31 (step S2). The document creation means 13 displays the review information contained in the review information file 37, and stores the information input from the creator for the document file 36 as document information (step S3). Furthermore, when the input of the information regarding correction is received from the creator with respect to the review information file 3, the information is stored as a review information file (step S4).

  If the document creation means 13 determines in step S1 that the new creation button has been pressed, the input information is recorded in the storage device as document information to create document information (step S5). After the “Create New” button is pressed, the program name and document name are accepted from the creator, and the document is specified by the program name and document name. In the processes of steps S3 and S5, the document information and the peer review information may be stored in the storage device as temporary information, or may be configured to be stored in the storage device in a file format. .

  Subsequently, the process proceeds to the process shown in FIG. 4. The document creation unit 13 transmits the document information and the review information (only the document information at the time of new creation) to the analysis server 300 via the communication unit 14 (step S11). . Since the document information includes the program name, document name, and version name (the same version name as when sent to the creation terminal 100) and the peer review information includes the program name and document name, the file of the analysis server 300 The management unit 34 determines whether there is a corresponding folder that matches the program name and document name of the document information (step S12). If the file management unit 34 determines in step S12 that the corresponding folder exists, the recording unit 32 compares the received document information with the document file stored in the corresponding folder, and stores the difference as a difference information file 38. To do. At this time, the version name of the difference information file 38 is searched for the version number of the difference information file 38 stored in the corresponding folder with the highest number, and the next number (the version name is managed in alphabets). If so, the next alphabetic character) is assigned as the plate name (step S13). Further, the recording means 32 stores the received document information as a document file 36 in the corresponding folder with the file name increased by one (newly) and stored (step S14), and the received review information is a review information file. 37 is stored in the corresponding folder (step S15).

  If the file management unit 34 determines in step S12 that there is no corresponding folder in which the program name and document name of the document information match, the received document information is stored as a document file 36 in the new folder. The name of the new folder includes the program name and document name. Further, at this timing, a new peer-review information file 37 is created (step S16). The process ends.

  Next, the flow of the peer review process will be described with reference to FIG. When the file management means 34 of the analysis server 300 detects that any one of the document files 36 has been updated, the processing is started, the peer review condition file 40 is referred to, and the peer reviewer corresponding to the relevant document file 36 is reviewed. The requested mail is transmitted (step S21). In the mail, the selection screen 25 shown in FIG. 2 can be displayed by describing the address to the web page dedicated to the reviewer.

  Next, the peer review processing means 22 of the peer review terminal 200 uses the display means 21 to display a document file list to be reviewed on the display device based on the peer review request. When the reviewer presses the “review” button, the corresponding document file 36 and the review information file 37 are received from the analysis server 300 via the communication means 24, and the review information from the reviewer is overwritten on the review information file 37. To do. Thereafter, at the timing when the reviewer presses the notification button, the review result input by the reviewer is held as review result information, and the review result information is transmitted to the analysis server 300 via the communication means 24 (step S22). .

  After detecting the reception of the review result information, the file management unit 34 of the analysis server 300 stores the review result information as the review information file 37 in the corresponding folder (step S23). The process ends. In addition, although it has comprised so that a request mail may be transmitted to a reviewer by step S21, you may comprise so that a reviewer may open a web page only for reviewers at arbitrary timings.

  The flow of analysis processing will be described with reference to FIGS. The processing starts, and the document creation means 13 of the creation terminal 100 accepts an analysis request when the creator presses an “analysis” button on the analysis screen 16, and transmits the analysis request to the analysis server 300 via the communication means 14. . Similarly, the review processing means 22 of the review terminal 200 accepts an analysis request when the reviewer presses an “analysis” button on the analysis screen 26, and transmits the analysis request to the analysis server 300 via the communication means 14. (Step S31). Although not shown, the author or reviewer may be configured to select the target document before pressing the "Analyze" button, or all documents specified by the author or reviewer will be analyzed. You may comprise so that it may perform.

  The recording unit 32 of the analysis server 300 inputs the difference information file 38 corresponding to the corresponding document, and reads the pre-change description amount, the post-change description amount, and the correction amount (step S32). After that, the analysis unit 35 calculates the correction rate for each section as the correction amount / post-change description amount in order to perform the comparison using the text correction rate illustrated in FIG. If there is a section that is not included, display data to be displayed as a warning target is stored in the analysis file 39 (step S33).

  Next, in order to perform the prediction of the remaining correction amount illustrated in FIG. 11, the analysis unit 35 reads the correction amount for each correction count from all the difference information files 38 and calculates the target value and the next correction amount prediction value. . Display data for displaying the correction amount for each correction count, the target value, and the next correction amount predicted value in a graph are stored in the analysis file 39 (step S34).

Next, in order to compare with similar projects, the analysis unit 35 performs regression analysis from the description amount and development amount of similar projects, and displays the validity of the document description amount (FIG. 12). Is created (step S35). The analysis unit 35 transmits display data to the creation terminal 100 or the peer review terminal 200 that requested the analysis (step S36), and the document creation unit 13 of the creation terminal 100 or the peer review processing unit 22 of the review terminal 200 The analysis data is displayed as a graph using the received display data (step S37).
Note that the processing in steps S35 to S35 may be performed not in this order but in any order, and may be configured to process only a part of the three analysis processes.

Details of the processing shown in step S33 will be described with reference to FIG. The analysis unit 35 calculates the correction rate for each section as the correction amount / post-change description amount using the pre-change description amount, the post-change description amount, and the correction amount read in step S32, and the document file The correction rate is stored in the analysis file 39 in association with the name and section name (step S41).
Next, the analyzing means 35 calculates an average value of the correction rate for one document, reads a predetermined target range value (upper and lower (±)% of the average value), and averages the average value as a central value. The upper limit value and lower limit value of the target range are calculated using the target range value. If there is a section whose correction rate is not included in the upper limit value and lower limit value of the target range, the “warning out of range” flag is set.
The calculated upper limit value, lower limit value, and “out of range warning” flag information are stored in the analysis file 39, and data for displaying a comparison based on the text correction rate in a graph is created. (Step S42). Although the average value is calculated in step S42, a median value may be calculated instead of the average value and set as the center value of the target range. The target range value is a numerical value indicating the allowable range of the correction rate determined in advance for each project, and is read in the process of step S42 as being stored in the project information DB 41.

  As shown in FIG. 10, the text correction rate for each section is displayed in a graph, and the target range is shown, so that it can be seen at a glance whether each section is outside the target range. For sections that are out of the target range, such as sections C and D, attention can be paid to the creator and reviewers by enclosing them with circles.

  If the text correction rate is larger than the target range, factors such as high system design difficulty and many specification changes may be considered. If it is smaller than the target range, factors such as low system design difficulty, high creator level, and insufficient review time are possible. From the analysis results, the creator and reviewers can be encouraged to consider the factors.

  Details of the process shown in step S34 will be described with reference to FIG. In order to predict the remaining correction amount, the analysis unit 35 arranges the correction amount input from one or more difference information files 38 in accordance with the correction order based on the version name including the file name of the difference information file 38. It memorize | stores in the analysis file 39 (step S51). Two correction amounts from the end of the number of corrections (correction amounts stored in the two difference information files 38 in the order of newest version names) are extracted, and correction fluctuation rate = (last correction amount / (last -1) correction amount) ) Is calculated. A numerical value obtained by multiplying the last correction amount by the correction fluctuation rate is determined as the next correction amount prediction value to be implemented in the future. A target value is calculated by multiplying a predetermined convergence value by a description amount. The calculated correction amount predicted value and target value information are stored in the analysis file 39 (step S52). The convergence value is an error tolerance rate determined in normal software development, is stored in the project information DB 41, and is read in the process of step S52.

  As shown in FIG. 11, by displaying the actual correction amount, the expected correction amount, and the target value for each correction number in a graph, whether the correction amount reaches the target value in the next peer review, and the difference from the target value. Can be confirmed. Projects usually have an error tolerance for errors, so the authors and reviewers are provided with information on how much the amount of corrections must converge to reach the target error tolerance. can do.

Details of the process shown in step S35 will be described with reference to FIG. The analysis unit 35 refers to the project information DB 41, extracts the latest difference information file 38 of the document related to the program included in the same project, and adds the changed description amount.
Further, the development amount included in the same project is read from the project information DB 41, all are added, and the changed description amount and the development amount are stored in the analysis file 39 (step S61). A regression line is calculated by regression analysis, and a predetermined target range (a fixed ratio with respect to the description amount) is used as graph data. The calculated information is stored in the analysis file 39 (step S62).

As shown in FIG. 12, by displaying the ratio between the development amount and the description amount for each project in a graph, it is possible to determine whether or not the document amount is appropriate with respect to the development amount, and when it is outside the target range Can review the amount of documents.
For example, if this analysis is performed before the document description is finished and development is started, if an analysis result with a document amount smaller than the (expected) development amount is obtained, the document is not sufficiently detailed. It is suggested to review the possibility. On the other hand, if an analysis result with a large document amount relative to the (expected) development amount is given, it is suggested that the (expected) development amount is less likely to be reviewed.

  As described above, according to the present embodiment, the creator creates and corrects the document, and the reviewer reviews the document and enters the review information (peer review comment) in the review information file 37. The analysis server 300 performs analysis processing. This eliminates the need for the creator, reviewer, or other manager to manually enter data relating to peer review, and allows data relating to quality to be analyzed.

The correction amount recorded in the difference information file 38 used in this embodiment is not only counted by the number of characters, but also the increase / decrease amount of the page number, the increase / decrease amount of the line number, the increase / decrease amount of the word number, The number of chapters and sections can be increased or decreased, and the number of paragraphs can be increased or decreased. In addition, the number of added, changed, or deleted portions can be counted instead of the number of characters.
Further, only specific words may be counted by changing the weighting. For example, it is possible to increase the weight for the word “security” or the word indicating a specific database name, and increase the weight for adding, changing, or deleting the corresponding word.
Also, even for the same word, change the weighting in the text and in the figure or table. For example, for the words in the figure or table, increase the weighting for the text. You may comprise.

  In the present embodiment, when expressed as a document, it indicates a printed matter or what is displayed on the screen of the creation terminal 100 or the peer review terminal 200, and when expressed as a document file, it is stored in the storage device in a file format. Or is exchanged via the network 400, and expressed as document information indicates information stored in the document file.

  For example, the creator and the reviewer can be appropriately changed so that the creator of the document A becomes the reviewer of the document B. In this case, the creation terminal 100 and the review terminal 200 are used as one terminal. By configuring, both operations can be performed by one terminal.

  In the present embodiment, the recording means 32 stores the difference between the first document information received from the creation terminal 100 and the document file 36 in the difference information file 38 and overwrites the document file 36 with the first document information. It is configured to do. Generally, there is an effect that the capacity of the storage device is not compressed by arranging only one document file 36 having a large outline and outputting only the difference to the difference information file 38. On the other hand, there is a case where a creator or a reviewer wants to confirm each version of the document file 36 later. Therefore, after creating the difference information file 38, the first document information is stored as a new document file 36. It is also possible to configure as described above. In this case, a plurality of document files 36 exist for each version.
