為了能在預定的時程內以合理的成本建立滿足使用者品質需求的軟體系統，專案管理者必須隨時掌握專案的流程、進度與各項資源的使用情形等相關資訊，才能在各種狀況發生的第一時間做出因應措施，而度量與分析（Measurement and Analysis, MA）活動的主要目的就是針對上述的目標進行資料收集，並將這些資料彙整成為有用的資訊，以做為決策制定時的重要參考依據。在實際的度量與分析活動中，為了因應各度量目標之涵蓋範圍大小的不同，度量與分析模式的階層架構通常需要具有彈性與延展性(Scalability)，然而現有的軟體度量與分析模式以及相關的度量與分析工具，其階層架構都是固定的，因此無法根據度量目標範圍的大小來動態地調整，因此在使用上也有很大的限制與不便。
基於上述問題，本研究提出了一個動態多層式軟體度量與分析模式。此模式可根據不同度量目標所涵蓋範圍的大小，動態地調整度量架構的階層數，讓每個度量專案建立符合該專案特性與需求之特定度量架構。同時，本研究也針對度量値提出操作型定義，以提昇度量資料收集的完整性與正確性，增加度量值重複使用的機會。此外，本研究還依據所提出的模式，開發出一套結合資料收集與分析資訊圖形呈現功能的動態多層式度量與分析工具(Dynamically Multi-Layered Measurement and Analysis Tool)，以支援軟體度量與分析活動的進行，並協助國內廠商提升度量與分析活動執行的效率。最後，本研究還利用一個簡單的範例來說明工具的各項操作，以驗證本研究所提出之模式與所開發工具的可用性。

In order to deliver high quality software systems that meet the users’ quality requirements within budget and on schedule, the project managers need to well control and monitor all development processes at any time of the life cycle, so they are able to identify problems and further perform preventive actions before they occur. Whereas the primary objective of software measurement and analysis (MA) is to collect measures and further analyze the collected measures for generating useful information needed for the continuous improvement or decision making. In practice﹐as the measurement objective has different sizes of the scope, the level of hierarchy of a MA model must have the property of elasticity and scalability. However, the level of hierarchy of the existing MA models and relevant tools are fixed and thus cannot be dynamically adjusted based on the different sizes of scope of measurement goals. Hence, they have very great restrictions and inconveniences for the use in the practice.
To address the above problem, this thesis presented a dynamically multi-layered software measurement and analysis model. This model can dynamically adjust the level of hierarchy of measurement and analysis models for calibrating different sizes of scope of the measurement goals of software development projects. Meanwhile, in order to obtain the integrity and accuracy of the collected measures and to increase the opportunities for reuse, the operational definition of a software measure was also presented in this thesis. Moreover, this thesis also developed a dynamically multi-layered measurement and analysis tool, which was based on the proposed model in this thesis. This tool can help domestic software industry efficiently perform the MA activities. Finally, this thesis used an example to demonstrate and also verify the usability of the proposed model and developed tool in this thesis.
