Selecting Suitable Software Effort Estimation Method

octubre 30 @ 10:05 am - 10:35 am

Effort estimation is one of the important factors affecting the success of software projects. In order to support this, many effort estimation methods have been developed from past to present. The reliability of the effort estimation of a project depends on the choice of the most appropriate method for the project characteristics and the estimation context. Even if a good performing method is used, the estimation results may remain to be inaccurate if an appropriate estimation method is not selected as appropriate to the project context. In this study, we proposed an approach for selecting the most suitable estimation method for a software project by considering the project characteristics and the stakeholder needs. An expert-opinion survey was prepared based on the key features of the commonly used estimation methods that have been frequently referred to in literature. The expert-opinion survey was answered by experts who carried out scientific studies in the field of software effort estimation, and a decision matrix was created in the light of their opinions. Then, a questionnaire was built for eliciting information about project characteristics from an estimator who wants to carry out effort estimation for his/her project. With the decision matrix, the estimator can select the most suitable method for his/her estimation by answering the questionnaire. A sample study was conducted and the questionnaire was answered using the ISBSG data set. At the end, the appropriateness of the proposed approach was discussed.
