When a file ID is used instead of recording a file name, a file and a version are recorded as one data, a change content is recorded in change information, The case where the team is not recorded can be considered, but in any case, the present embodiment is essentially applicable.

  Next, the operation will be described.

(Processing of the file reception unit 20)
FIG. 5 is a UML activity diagram showing the processing procedure of the file reception unit 20.
(Step 1.) The file reception unit 20 receives an input of a file (file name, file content) and a user name via the input unit 10.
(Step 2.) The file reception unit 20 acquires the current date and time as the change date and time in order to record the change information. The current date and time is obtained from, for example, an OS (Operating System).
(Step 3.) The file receiving unit 20 generates change information including the user name and the change date and time.
(Step 4.) The file receiving unit 20 compares the file content of the file stored in the storage unit 30 with the file content of the input file.
(Step 5.) When the file contents are the same, the file receiving unit 20 ends the process. If the file contents are different, the process proceeds to step 6.
(Step 6.) The file receiving unit 20 registers the file (file name, file content) and the change information in the storage unit 30. Further, at the time of registration, a version number and a file ID for distinguishing the contents of files having the same file name are assigned. The file receiving unit 20 stores the version number, the received file (file name, file content), and the change information in the storage unit 30 in association with each other.

FIG. 6 is a diagram illustrating, for example, the state of the storage unit 30 at a certain point of time in a UML object diagram. FIG. 6 shows a state where no file is registered yet. In FIG. 6, the project organization table data is recorded in advance, and there are Taro, Jiro, and Saburo as developers. Taro and Jiro belong to the library development team, and the entire project team includes the library development team and Saburo. Indicates that it belongs to.
FIG. 7 shows that from the state of FIG. A state after Java (registered trademark) is registered at 0:00:00 on January 1, 2008 is shown. In FIG. 7, the newly registered file main. Java (registered trademark), version (version number 1), file contents, and change information are recorded, and the change information records that Taro has changed.
FIG. 8 shows that from the state of FIG. The state after changing the contents of Java (registered trademark) at 11:00:01 on January 1, 2008 is shown. In FIG. 8, the file main. A new version (version number 2), contents, and change information are recorded in Java (registered trademark), and the change information records that Taro has changed.

(Process of affected file detection unit 52)
FIG. 9 shows the processing procedure of the affected file detection unit 52. In the inter-product dependency estimation apparatus 1001 according to the first embodiment, a file (file name, file content) is received by the file receiving unit 20 and sequentially stored in the storage unit 30, and the input unit 10 and changed portion input In this embodiment, when a file name is input to the affected file detection unit 52 via the unit 40, an accuracy calculation unit 51 described later is activated.
(Step 1.) The affected file detection unit 52 receives an input of a file name via the input unit 10 and the changed part input unit 40.
(Step 2.) The affected file detection unit 52 passes the input file name to the accuracy calculation unit 51, and the dependency relationship between the file represented by the input file name and the file represented by another file name The accuracy is calculated using the accuracy calculation unit 51.
(Step 3.) The affected file detection unit 52 receives the accuracy of dependency between files from the accuracy calculation unit 51, and uses the input file name as the affected file and other files as the affected file. Further, the accuracy of the dependency relationship is added, and the list is passed to the output unit 60.

(Processing of the accuracy calculation unit 51)
FIG. 10 shows a processing procedure of the accuracy calculation unit 51. As an example, it is assumed that the file name A is input from the affected file detector 52, and the recorded change information is as shown in FIG.
(Step 1.) The accuracy calculation unit 51 searches for and identifies the version having the file name input from the affected file detection unit 52 from the latest version (version number) of the file. Then, change information corresponding to the version is specified. Then, the change information immediately after that is paired. Furthermore, past versions of the same file are tracked, and the change information and the change information immediately after that are paired. For example, if the change information of the file A is specified as shown in FIG. 12, the accuracy calculation unit 51 extracts the change information immediately after it as a pair. As a result, five pairs of (A, B), (A, C), (A, B), (A, D), and (A, B) are extracted.
(Step 2.) The accuracy calculation unit 51 selects only pairs in which the changers corresponding to each change information are the same for the change information pairs. For example, in FIG. 1 and 2 are selected because the changer is taro. On the other hand, the change information No. In 20 and 21, since file A is changed to taro and file D is changed to jiro, they are not selected. The selection result is as shown in FIG.
(Step 3.) The accuracy calculation unit 51 receives the set of selected pairs of change information as input and calculates the accuracy of the dependency relationship using an accuracy function. As the accuracy function, for example, a function called “sum of reciprocals of change time difference (unit: minutes)” so that the accuracy becomes higher as the change time difference is shorter can be considered. FIG. 15 shows the output in such a case. In addition, as a method of extracting a pair of change information, as shown in FIG. 16, all files changed between a change of a certain file (A in FIG. 16) and the next change can be used. Various methods other than the method of forming a pair are conceivable.

(Accuracy function variation)
In addition to the accuracy function, various other functions can be considered, including the following.
(1) A function having a change time difference as a parameter, such as “sum of inverse square of change time difference”.
(2) A function having a change amount as a parameter. If the contents are changed drastically, there is a high possibility that the dependency relationship will be changed so far, which is useful when it is necessary to relatively increase the accuracy of the dependency relationship due to the latest change.
(3) A function having the change time as a parameter. This is useful for lowering the dependency when resting or at night.

  In addition, as a method for selecting a pair of change information, there may be a case where another user who belongs to the same team changes the information. In that case, as the accuracy function, a function (such as a weighted sum) having an argument of the accuracy when the same user changes and the accuracy when a different user who belongs to the same team changes can be considered.

  As described above, by calculating the accuracy of the dependency relationship using the change information etc., the dependency relationship can be followed along with the file content change, and the user can delete the dependency relationship by mistake. Can be prevented.

Embodiment 2. FIG.
The second embodiment will be described with reference to FIGS. In the second embodiment, the following functions are added from the first embodiment.

(2) Change request form:
The change request form records a product that needs to be changed by another development team with respect to a product changed by a certain development team.

  Next, data held in the storage unit 30 will be described. FIG. 42 shows data held in the storage unit 30.

(1) Accuracy calculation program 64:
The accuracy calculation program 64 is a program for calculating or setting the accuracy between deliverables. For example, (a) a program executed by the dependency relationship manual setting unit 601 and (b) a program executed by the dependency relationship extraction unit 602 shown in the functional configuration diagram of the sixth embodiment,
(C) The program executed by the overall accuracy calculation unit (51-6) is applicable. Further, the program executed by the accuracy calculation unit 51 in (d) of the fifth embodiment is also applicable. Other,
(E) Various programs are conceivable, including a program that calculates the degree of similarity between deliverables using words that appear in the deliverables and outputs them as the accuracy of dependency.

In the accuracy calculation program 64 of FIG. 42, whether or not to start the accuracy calculation program 64 when a product is changed is executed when the product in the storage unit 30 is changed via the product reception unit 20. The presence / absence of setting is determined in consideration of the power accuracy calculation program 64. For example,
Accuracy calculation program 64 of (a), (b) and (c) above
Does not need to be started when changing,
The programs (d) and (e) need to be activated when they are changed.

Similarly, in the accuracy calculation program 64 of FIG. 42, whether or not the accuracy calculation program 64 is activated when a product is taken out is determined when the product in the storage unit 30 is taken out via the product take-out unit 301. The presence / absence of the setting is determined in consideration of the accuracy calculation program 64 to be executed. For example, the accuracy calculation program 64 (a), (b), (c), and (e) does not need to be activated at the time of reading, but (d) requires activation at the time of reading.

(2) Dependency 63:
In the dependency relationship 63 of FIG. 42, the dependency relationship between deliverables is recorded. In addition to the accuracy, record the date and time of the calculation and whether it is a dependency to be fixed. One dependency is recorded for each set of the influence source product, the influence destination product, the accuracy calculation program 64, and the calculated date and time.

* In the calculated date and time, the date and time when the accuracy calculation program 64 outputs the accuracy is recorded. The data may be recorded for the purpose of calculating the total accuracy in consideration of the possibility that the manually set date and time may be recorded and the maintenance may not be performed with time.

  * It is data for artificially setting that there is a dependency regardless of the accuracy of the dependency, whether the dependency should be fixed. This data is recorded for the purpose of, for example, manually determining the dependency after conducting a detailed investigation of the dependency between deliverables.

(1) Documents to be changed:
The change target description document is a document in which a product (for example, a file) to be changed is described in the project management document data. For example, the change target description document A includes information that the file X, the file Y, and the file Z are files that need to be changed.
(2) Dependency description document:
The dependency description document is a document in which the impact source product and the impact target product are described in the document data for project management. The dependency relationship description document B includes, for example, information that the file X is an influence source and the file Y is an influence destination. Other data is the same as in the fifth embodiment.

  FIG. 43 is a diagram for explaining the main operation of the sixth embodiment. FIG. 44 is a diagram for explaining processing of a change target description document according to the sixth embodiment. First, a description will be given with reference to FIG.

(1) The product receiving unit 20 receives input of product data including a product name that is the name of a product and product content that is the content of the product. The product receiving unit 20 determines whether or not product data having the same product content as the received product content exists in the storage unit 30 as in the case of the first embodiment or the fifth embodiment. When the product receiving unit 20 determines that the product does not exist, the product receiving unit 20 assigns a version number for distinguishing product data having the same product name to the received product data, and the assigned version number, the received product data, Are stored in the storage unit 30 in association with each other. FIG. 43 shows a state in which the product data X1 (version number 1), product data Y1 (version number 1), and product data Z1 (version number 1) are stored in the storage unit 30.
(2) In addition, the dependency relationship manual setting unit 601 (dependency relationship receiving unit) determines the influence destination affected by the change of the product name of the product data that is the influence source and the product content of the product data of the influence source. The storage unit 30 receives an input of a product name pair consisting of a product name of product data of the product data and a specified pair that is specified in advance, and the accuracy of dependency that is set in advance for the specified pair. To record. FIG. 43 shows a case where the designated pair of the influence source “X” and the influence destination “Y” and the accuracy 3 are received.
(3) The accuracy calculation unit 51 (individual accuracy calculation unit) receives the product name and uses the received product name that is the received product name among the product data stored in the storage unit 30 as an influence source. , Create a pair of product names that are affected by the change of the product content of the product data of the received product name of the received product name of the product data stored in the storage unit 30 Create as a pair. The accuracy calculation unit 51 acquires the received product name from the storage unit 30 or the affected product detection unit 52 every time a product is stored or every time a product is taken out. The acquisition path can be freely set by the implementation. Then, the accuracy calculation unit 51 sets the accuracy of the dependency relationship between the product data having the received product name of the influence source and the product data having the product name of the influence destination for each of the created pairs. By executing the calculation program, each accuracy calculation program is calculated individually. FIG. 43 shows a case where the accuracy calculation unit 51 accepts “deliverable product name = X” as the accepted deliverable product name. When the accuracy calculation unit 51 receives “product name = X”, the accuracy calculation unit 51 uses “X” as an influence source, and the created pair “X, Y”, “ X, Z ". “X, X” is not shown in FIG. 43, but may be created. As shown in FIG. 43, the accuracy calculation unit 51 (individual accuracy calculation unit) uses a plurality of accuracy calculation programs P1 to Pn having different rules for determining the accuracy, and uses “X, Y”, “X, Z”. Calculate the accuracy of the created pair.
(4) The overall accuracy calculation unit (51-6) receives the reception result among the accuracy of each of the created pairs calculated individually by the accuracy calculation unit 51 and the accuracy recorded in the storage unit 30 by the dependency relationship manual setting unit 601. Using the accuracy of the specified pair with the object name as the influence source, the accuracy of the dependency for each created pair is recalculated as the overall accuracy. That is, the total accuracy calculation unit (51-6), for “X, Y”, each accuracy calculated by the accuracy calculation programs P1 to Pn and the specified pair “X → Y” recorded by the dependency relationship manual setting unit 601. = 3 ”is used to calculate the total accuracy of the created pair“ X, Y ”, and the accuracy of the created pair“ X, Z ”is calculated by the accuracy calculation programs P1 to Pn. The total accuracy is calculated from each accuracy.
(5) In addition, the dependency relationship manual setting unit 601 receives input of a specified pair and dependency relationship determination instruction information for instructing determination of the dependency relationship of the specified pair. FIG. 43 shows a case where the dependency relationship manual setting unit 601 receives a specified pair “X, Z” and dependency relationship determination instruction information about the specified pair. The overall accuracy calculation unit (51-6) records the dependency relationship of the specified pair corresponding to the dependency relationship determination instruction information received by the dependency relationship manual setting unit 601 as confirmed, and records it in the storage unit 30. That is, in the case of FIG. 43, the total accuracy calculation unit (51-6) records the dependency relationship of the designated pair “X, Z” in the storage unit 30 as confirmed.

(In the case of documents to be changed)
FIG. 44 shows a case where the product receiving unit 20 receives a change target description document.
(1) In the change target description document, n product names (n is an integer of 2 or more) of product data whose product content is scheduled to be changed are described. FIG. 44 is an example in which two product names “X” and “Y” are described.
(2) On the other hand, the storage unit 30 has _n P _two product name pairs that can be generated from the _n product names described in the change target description document. A pair that is affected by the change of the product content of the original product data, and the accuracy of the dependency set for each pair are stored. For example, in the example of FIG. 44, data “X → Y = 4” and “Y → X = 1” are stored in advance. The file name “X” or the like is a product that is expected to appear in normal program development, and the dependency relationship is stored in the storage unit 30 in advance.
(3) The dependency relationship extraction unit 602 extracts, from the storage unit 30, the accuracy of _n P _two pairs of dependency relationships stored in the storage unit 30. In the example of FIG. 44, the dependency relationship extraction unit 602 extracts information of “X → Y = 4” and “Y → X = 1” from the storage unit 30.
(4) The overall accuracy calculation unit (51-6) selects the name of the received product among the individual accuracy calculated by the accuracy calculation unit 51 and the accuracy recorded in the storage unit 30 by the dependency relationship manual setting unit 601. In addition to the accuracy of the specified pair as the influence source, the overall accuracy for each created pair is recalculated using the accuracy of the dependency relationship extracted by the dependency relationship extraction unit 602. For example, for the created pair “X → Y”, the total accuracy calculation unit (51-6) records “X → Y” recorded as the accuracy of each accuracy calculated from the accuracy calculation programs P1 to Pn and the dependency of the specified pair. The total accuracy is calculated from the accuracy “3” of “= 3” and the accuracy “4” of “X → Y = 4” extracted by the dependency relationship extraction unit 602.

(For dependency description documents)
The case of a dependency description document will be described.
(1) The product receiving unit 20 is a dependency description document in which a pair of an affected product name and an affected product name affected by a change in the product content of the affected product data is described. Is received and stored in the storage unit. For example, a dependency relationship “X → Y” (where X is the name of the affected product and Z is the affected product name) is described.
(2) The storage unit 30 stores a pair described in the dependency relationship description document and the accuracy of the dependency relationship set in the pair. For example, when “X → Y” is described in the dependency relationship description document, the storage unit 30 stores data such as “X → Y = 5”. In this sense, the change target description document and the dependency relationship description document described above set the dependency relationship between deliverables in a so-called “semi-manual” manner.
(3) The dependency relationship extraction unit 602 extracts the accuracy of the pair dependency relationship described in the dependency relationship description document from the storage unit 30. For example, the dependency relationship extraction unit 602 extracts “X → Y = 5” data from the storage unit 30.
(4) The total accuracy calculation unit uses the received product name as an influence source among the accuracy calculated individually by the accuracy calculation unit 51 and the accuracy recorded in the storage unit 30 by the dependency relationship manual setting unit 601. In addition to the accuracy of the specified pair, the overall accuracy for each created pair is recalculated using the accuracy of the dependency relationship extracted by the dependency relationship extraction unit 602.

Next, a specific operation will be described. The processing procedure of the dependency relationship manual setting unit 601 is shown in FIG.
(Step 1.) An input of an influence source product name, an influence target product name, accuracy, and a confirmed dependency relationship is received.
(Step 2.) The dependency is recorded in the storage unit 30.

The processing procedure of the dependency relationship extraction unit 602 is shown in FIG.
(Step 1.) The dependency relationship extraction unit 602 checks the type of the changed document.
(Step 2.) In the case of a document to be changed, the process proceeds to Step 3. In the case of a dependency description document, the process proceeds to Step 4.
(Step 3. Document to be changed)
Extract the target product from the target document. To extract, the program to be extracted is recorded in the storage unit 30 in advance and executed.
(Step 4) The mutual dependency relation is recorded in the storage unit 30 for the extracted change target product. The numerical value of the accuracy to be recorded and whether or not the dependency to be determined is recorded in the storage unit 30 in advance. When the change target description document A includes information that the files X, Y, and Z need to be changed as in the above-described example, the dependency extraction unit 602 determines that “X (influence source) → Y (influence destination)”. , “Y → X”, “Y → Z”, “Z → Y”, “Z → X”, “X → Z”, ( ₃ P ₂ ) accuracy of dependency, and accuracy determined for each Whether or not information is recorded. The dependency between two files and the accuracy thereof are set in the storage unit 30 in advance. That is, when the change target file X, Y, Z is described in the change target description document A, the dependency relationship extraction unit 602 determines the dependency relationship such as “X → Y” already set in the storage unit 30. Search and get the accuracy of. In this sense, dependency is set to “semi-manual”.
(Step 5. Dependency description document)
Extract the affected product and the affected product from the dependency description document. To extract, the program to be extracted is recorded in the storage unit 30 in advance and executed.
(Step 6.) The dependency relationship (accuracy and information on whether or not the dependency relationship should be determined) between the affected source product and the affected product is recorded in the storage unit 30. The numerical value of the accuracy to be recorded and whether or not the dependency to be determined is recorded in the storage unit 30 in advance. When the dependency relationship description document B includes the dependency relationship “X → Y” as in the above example, the dependency relationship extraction unit 602 determines that the dependency relationship “X → Y” is already stored in the storage unit 30. The accuracy of the relationship is acquired, and the accuracy of “X → Y” is recorded in the storage unit 30.

  The processing procedure of the product receiving unit 20 is shown in FIG. Steps 1 to 6 are the same as those in the fifth embodiment. In step 7, among the accuracy calculation programs recorded in the storage unit 30, all the accuracy calculation programs 64 recorded when activated when activated are activated.

  The processing procedure of the product takeout unit 301 is shown in FIG. Steps 1 to 3 and step 5 are the same as steps 1 to 4 in the fifth embodiment. In step 4, among the accuracy calculation programs 64 recorded in the storage unit 30, all the accuracy calculation programs 64 that are recorded when activated when the deliverables are taken out are activated.

The processing procedure of the total accuracy calculation unit (51-6) is shown in FIG. The total accuracy calculation unit (51-6) is activated upon detection that the accuracy of the dependency relationship calculated by the various accuracy calculation programs 64 has been updated.
(Step 1.) The latest dependency relationship is extracted for each accuracy calculation program 64 other than the overall accuracy calculation unit (51-6) for the set of the influence source product and the influence target product.
(Step 2.) When the dependency relationship to be determined is included for each set of the influence source product and the influence target product, the process proceeds to Step 3. If not included, the process proceeds to step 4.
(Step 3.) Since it is clearly stated that the dependency is to be confirmed, it is recorded in the storage unit 30 as the dependency to be confirmed.
(Step 4.) Based on the accuracy calculated by the various accuracy calculation programs 64, the overall accuracy is calculated using the overall accuracy function. Various types of total accuracy functions are conceivable, including “the sum of the accuracy weighted by the elapsed time from the accuracy calculation date and time”.
(Step 5.) The calculated total accuracy is recorded in the storage unit 30 as a dependency by the total accuracy calculation unit (51-6).

  The processing procedure of the affected product detection unit 52 is shown in FIG. Step 1 and steps 3 to 4 are the same as those in the fifth embodiment. Step 2 obtains, from the storage unit 30, a dependency that is affected only by the product included in the set of product names that are input, only for the dependency recorded by the specified accuracy calculation program 64. When displaying the dependence relationship based on the overall accuracy, the overall accuracy calculation unit (51-6) is designated, and when displaying the dependency relationship recorded by the individual accuracy calculation unit 51, the individual accuracy is displayed. The calculation unit 51 is designated. The calculation unit designation method includes a method of recording in the storage unit 30 in advance or inputting from the input unit 10.

  By doing so, the dependency relationship entered by the user or the dependency relationship described in the document data for project management written by the user is used, or there is a dependency relationship between the deliverables that do not have the dependency relationship. Although there is a relationship, the risk of estimating that there is no dependency between deliverables can be reduced.
