PENGUKURAN FUNGSIONALITAS PERANGKAT LUNAK MENGGUNAKAN METODE FUNCTION POINT BERDASARKAN DOKUMENTASI DESAIN

Estimated value of software as agreed by the end user and the developer team should be expressed in a certain magnitude, one of which is the measure of functionality (functional size measurement / FSM). Function Point (FP) Method is one of the methods used to obtain the size of the functionality, first introduced by Allan Albrecht and then further developed by the International Function Point User Goup (IFPUG). FP is a method used to get a measure of the cost, duration, and amount of resources required by a software project and can be done at any stage of software development. However, Function Point measurement requires expertise in software analysis and the results of the calculation are valid if done by someone with IFPUG certification. This study realizes a system that is convenient for actors in analyzing software using Function Point method based on IFPUG CPM 4.3.1. The system helps users to perform FP analysis in a faster way and confers accurate results. The system is able to count FP based on software design documentation and uses XMI document exported from use case diagrams, class diagrams, and diagrams illustrating the use cases and classes relationship as an input. The study also indicates that the more complete software UML (Unified Modeling Language) documents, the more accurate the FP calculation results obtained
