Although the actual rules for counting function points are complex, the underlying principles are straight-forward. The five major components of the function point metric consist of enumerating these items for an application being sized and estimated: The inputs to the application The outputs that leave the application The logical files maintained by the application The kinds of inquiries that the application supports The interfaces between the application and other applications The details of how function points are actually counted are beyond the scope of this article.
For a full discussion, refer to the books cited the references and reading list at the end of the article. The ability to use function point metrics as the basis of sizing is the fact that they can be enumerated directly from a statement of the requirements of an application.
Once the function point total of an application is calculated, then sizing of most deliverable items becomes comparatively straight-forward. By fortunate coincidence the structure of function point metrics are a good match to the fundamental issues that should be included in software requirements. In chronological order seven fundamental topics should be explored as part of the requirements gathering process:. The similarity between the topics that need to be examined when gathering requirements and those used by the functional metrics makes the derivation of function point totals during requirements a fairly straightforward task.
There is such a strong synergy between requirements and function point analysis that it would be possible to construct a combined requirements analysis tool with full function point sizing support as a natural adjunct, although the current generation of automated requirements tools are not quite at that point.
If full automation of both requirements and function points are to be possible, the requirements themselves must be fairly well structured and complete. Toward that end, in addition to the seven fundamental requirement topics there are also thirteen other ancillary topics that should be resolved during the requirements gathering phase:. These 13 supplemental topics are not the only items that can be included in requirements, but none of these 13 should be omitted by accident since they can all have a significant affect on software projects.
The synergy between function points and software requirements is good enough so that it is now technically possible to merge the requirements gathering process and the development of function point metrics, and improve both tasks simultaneously. In the future, automated tools that support both requirements gathering and function point analysis could add rigor and improve the speed of both activities.
Since requirements gathering has been notoriously difficult and error-prone, this synergy could benefit the entire software engineering domain. Once function point totals have been developed, the information can be used to size any and all software deliverables. Following are several examples. Software development is a very paper-intensive occupation. As many as 50 different kinds of planning documents, specifications, control documents, and user manuals have been observed on large software systems.
It is interesting that the volumes of paper deliverables vary significantly from industry to industry. Military software projects produce far and away the largest volume of paperwork of any known kind of software. Here are selected size examples, drawn from systems, MIS, military, and commercial software domains. In this context, "systems" software is that which controls physical devices such as computers or telecommunication systems. MIS software stands for "management information systems" and refers to the normal business software used by companies for internal operations.
Military software constitutes all projects which are constrained to follow various military standards. Commercial software refers to ordinary packaged software such as word processors, spreadsheets, and the like. This kind of sizing for software documentation is now a standard feature of several commercial software cost estimating tools.
At least one commercial software estimating tool can even predict the number of English words in the document set, and also the numbers of diagrams that are likely to be present, and can change the page count estimates based on type size. Since software is now a global commodity, some software cost estimating tools can also predict document volumes and translation costs for converting screens and text into various national languages such as Japanese, French, and German.
Another major sizing capability associated with function point metrics is the ability to predict source code size for any programming language, or even for applications that use two or more languages at the same time such as Java and HTML, or COBOL and SQL for older applications. As of there are more than programming languages and dialects in existence. There are far too many languages to do more than illustrate the concept, but source code sizing consists of predicting the number of logical statements that will be needed to encode one function point.
Once the function point total of an application is calculated, it is possible to predict the approximate volume of source code in new applications. For greater precision, adjustments can be made for complexity and programming styles by specific teams. Most commercial software cost estimating tools in include source-code sizing from function point metrics. Some cost estimating tools also include more accurate size predictions than just a table look-up based on average values.
For greater accuracy, it is necessary to include adjustments for both complexity and for reusable code. It is also necessary to deal with applications that include multiple programming languages. However, all of these capabilities are now available in commercial software estimating tools. The most time-consuming and expensive activities for software projects are those concerned with finding and removing bugs or defects.
Thus accurate cost estimation is built on the ability to predict both the numbers of potential defects that might occur, and the costs and schedules of various defect removal operations.
These numbers represent the total numbers of defects that are found and measured from early software requirements throughout the remainder of the life cycle of the software. The defects are discovered via requirement reviews, design reviews, code inspections, all forms of testing, and user-reported problem reports. Another useful sizing capability associated with function point metrics is the ability to predict the number of test cases that are likely to be created for the application.
Here too, there are major differences in test case numbers by industry, with military software and systems software producing much larger totals of test cases than information systems.
There is now at least preliminary data available for all standard kinds of testing. Home Standards Software Sizing Standards. Software Sizing Standards Software sizing is used to estimate the size of a software application or component to support cost estimating, progress tracking, and other software project management activities.
CISQ has published two standards for automating the measurement of software size: Automated Function Points measure the functional size of software.
