Title Research and Implementation of NESMA Function Point
Estimation Method and its Supporting Tools
Abstract
As software systems' size becomes larger and more complex, estimation plays a vital role in the success of software project. The function point methods with the advantage of being independent of the specific development technology have gradually been the industry's attention and respected. However, the concepts of function point method are abstract, the identification rules are too many and the counting procedure is very complex, which makes it difficult to popularize. Therefore, how to make users quickly grasp the estimation method and process becomes a research hotspot.
In the dissertation, the NESMA function point software size estimation methods are researched, the main content includes the following aspects:
(1) Simplified process of NESMA function point estimation method. As the concept in NESMA is difficult to understand, data models are introduced to simplify the identification procedure of NESMA components. And a questionnaire is designed to help users to understand and use.
(2) Design and Implementation of NESMA estimation tool. Tool achieves NESMA function point estimation method, and is posted as a website for users’ online estimation. It guides users to estimate size, schedule and cost and lets users understand the NESMA method meanwhile.
