摘要

功能點常被用在專案開發的時候，用來估計專案規模的指標，因其與語言無關，所以也可以用於生產力的評估與分析。在本文中我們使用IFPUG[1]、COSMIC[2]和MK II[3]三種方法來估算專案大小，並搜集三個專案工時，對之來進行迴歸分析，用來檢驗功能點與工時的相關性。分析的結果發現功能點的估算在有一定的流程和架構的專案中，採用IFPUG和COSMIC的預測是比較好的，而在沒有一定的流程和架構的專案中，則是採用MK II得到的預測結果比較好。

Function point is usually used to estimate the scale of a project during early stage of project development. Because it is language-independent, it could also be used for the assessment and analysis of productivities. In this thesis, we used three methods to estimate the project size: 1. IFPUG, 2. COSMIC, and 3. MK II. We also collected the work efforts of three different projects. We used linear regression to analyze the relationship between function point and work efforts. From the results of analysis, we found that for projects with more stable process and more organized structure, IFPUG and COSMIC are better predictors. Otherwise, MK II makes better prediction of efforts.
