| Abstract [eng] |
To effectively manage software development we must be able to measure software. Alan Albrecht in IBM Corporation in 1979 proposed the use of function point analysis method. This method measures functionality provided to the user by the software and is independent of the used software development technology. There are currently 5 standardized function point analysis methods, which use different rules for software size measurement. In this work estimation criteria are defined and used to compare standardized IFPUG, Mark II, COSMIC, NESMA and FiSMA function point analysis methods. During the comparison of methods their conceptual similarities and differences, standardization, availability of industry data, convertibility, the most suitable usage phase, subjectivity of measurement rules, estimation of non-functional user requirements, availability of certification and counting practices manuals, supporting software tools and the scope of methods applicability are examined. The analysis results show that the best choice is IFPUG or COSMIC methods. |
