  In all the drawings for describing the embodiments, the same members are denoted by the same reference numerals in principle, and the repeated description thereof will be omitted.

  FIG. 1 is a block diagram of a software development estimation support system according to the present embodiment. The software development estimation support system 1 is one in which the user 10 directly operates and uses the estimation support device 100, but is not limited thereto, and uses the information processing terminal (not shown) via a browser or the like. It may be connected to and used.

Connected via a network. The network may be a VPN (Virtual Private Network) on a wireless communication network such as a mobile phone communication network.

  As an application example of the software development estimation support system 1, the software development estimation support system 1 is used for estimating a predetermined software product in-house when developing the software product, or for solving a management problem of a predetermined customer. It can be used for estimating software development in various situations, such as when it is used for estimation in demand development.

  At that time, the user 10 can generally use various estimation methods, and one of them is a method of estimating the cost according to the amount of the development product. For example, the cost is estimated using factors such as the number of screens, the number of screen items, the number of database tables, the number of items in the database tables, the number of processes of business logic and the like, the development language, developer skills, and the like. Further, as a more accurate estimation method, there is a method of discriminating, for each of the number of screens, the number of screen items, and the number of processes, whether the process is accompanied by a process of performing only a reference or involves an update process.

The man-hour coefficient is a coefficient used when the man-hour is considered and calculated on the basis of the case where a standard-level engineer performs the man-hour. For example, a case where a standard-level technician works with a man-hour of “10 man days” is equivalent to a case where a high-level technician works with a man-hour of “8 man days” The man-hour coefficient is set to "0.8".

A predetermined number of actual values close to each factor may be extracted. Further, the similar case extraction unit 123 may calculate a value with a predetermined weight for each characteristic value (factor) of the deliverable, and determine the closeness to the estimated result.

You may make it calculate. Further, since the calculated average value is the standard man-hour, the estimated man-hour calculation unit 124 calculates the man-hour according to the skill ratio of the developer of the estimate request project.

  Next, the operation of the software development estimation support system 1 according to the present embodiment will be described.

  FIG. 7 is a diagram illustrating an example of the flow of the estimation support processing. The estimation support process is started in response to a start instruction from the user 10.

  First, the estimate request data input receiving unit 121 performs an estimate request data input reception process (step S001). Specifically, the quote request data input accepting unit 121 presents a predetermined screen, and regarding a software development project to be estimated, a computer language used for development and a factor related to estimation such as a characteristic value of a predetermined product. , Input is accepted. More specifically, the estimate request data input receiving unit 121 determines the number of reference screens, the number of reference screen items, the number of update screens, the number of update screen items, the number of tables, the number of table items, the number of reference processes, , The number of update processes, the development language, the ratio of high skill developers, the ratio of standard skill developers, and the ratio of inexperienced developers are received and stored in the estimate request table storage unit 111. Note that the characteristic value of the product includes at least the number of input / output items, the number of data items, and the number of processing units in each of the reference process and the update process.

  At this time, the estimation request data input receiving unit 121 calculates and adds the ratio of the absolute number of the item having the notation (ratio) to the total amount of the item having the notation (ratio) in addition to the absolute number for the item having the notation (ratio). Store. For example, the number of reference screens is “20”, the number of reference screen items is “100”, the number of update screens is “30”, the number of update screen items is “100”, the number of tables is “30”, and the number of table items is “300”. , The number of reference screens is “0.029”, the number of reference screen items is “0.147”, and the number of updated screens is “0.147”. The number of screens is "0.044", the number of updated screen items is "0.147", the number of tables is "0.044", the number of table items is "0.441", the number of reference processes is "0.075", the update The number of processes is calculated as “0.075”. In the above ratio, the number of significant digits is set to the third decimal place. However, the present invention is not limited to this. The number of significant digits may be up to the second decimal place or may be more. Needless to say, it may be expressed as a percentage.

  Then, the performance extracting unit 122 extracts a performance population (step S002). Specifically, the performance extracting unit 122 extracts, as a performance population, a record in which the development language 112M of the estimated performance table storage unit 112 matches the computer language used for development received in step S001.

  Then, the performance extracting unit 122 calculates a difference value (Step S003). Specifically, the performance extracting unit 122 calculates, for each of the development projects belonging to the extracted performance population, the absolute value of the difference from the factor related to the estimation such as the characteristic value of the predetermined product received in step S001.

  Then, the performance extracting unit 122 calculates a ratio difference value (Step S004).

More specifically, the similar case extraction unit 123 acquires the absolute values of the difference value and the ratio difference value calculated in steps S003 and S004, and specifies a predetermined number of similar cases with small cumulative values as similar cases. For example, the similar case extraction unit 123 identifies 10 cases, which are a total of 5 cases with a small difference value and 5 cases with a small ratio difference value, as a similar case. Exclusion may be performed, or duplication may be permitted). For this similarity determination, various similarity determination criteria can be adopted as described above, and for example, the determination is made by obtaining the Euclidean distance, the Mahalanobis distance, or a combination thereof.

  Then, the estimated man-hour calculation unit 124 calculates the man-hour estimate (Step S006). Specifically, the estimated man-hour calculation unit 124 obtains the actual man-hours of each similar development project extracted by the similar case extraction unit 123 in step S005, and converts the skill ratio of the developer back to the standard man-hour. Above, the average value is calculated.
