功能點分析是目前最廣泛被使用的軟體功能性大小度量方法論，僅管其定義的43條自然語言法則與功能複雜性權重可以提供量化的大小度量值來支援成本與時程預估的活動，然而卻也衍生出新的實務使用問題：(1)各功能性元件間彼此相互獨立；(2)自然語言之判斷規則不易使用；(3)度量步驟過於繁瑣等缺點。因此，為了提昇度量結果之確準性以及改善功能點分析之能力，本研究將建立一個以網路分析法為基礎之敏捷功能點計算模式，以網路分析法來度量軟體的功能性大小，其中計算模式並包含以下四個特點：(1)考量功能性元件的相依性以完整反映系統功能全貌；(2)減少需要使用的FPA規則以加速度量時間；(3)容易在開發早期進行度量以提供近似真實FPA的結果；(4)排除使用複雜度等級權重的規則以克服權重值久未更新的問題。本研究除了上述特點之外，亦透過發票處理系統的實務個案度量來驗證本研究成果的可行性。

Functional Point Analysis (FPA) is a widely adopted approach that measures the functional size of software systems. This approach uses 43 rules for counting function points provide a quantifiable size measure to support the cost and schedule evaluations. These evaluations are complex and stretch their use of new practical questions. This study integrated Analytic Network Process and FPA to develop agile function point counting approach. Four main advantages of this approach are (1) the interdependence among base functional components (BFCs) to reflect a complete profile of functions; (2) reducing used rules of FPA to improve the efficiency of measurement; (3) measuring in the early stage to provide approximated FPA results; and (4) excluding the rules associated functional complexity to overcome the un-updated problem for weighted values of functional complexity. An invoicing system is presented to illustrate the use of this approach to confirm the feasibility of this approach.
