Abstract: This paper describes a multi-method approach utilized at ABB to derive size and effort estimates at the planning stage of software development projects. The planning stage is the stage where the organization has more insights into the project that at the initial conceptual stage. This does not mean that uncertainty is totally eliminated but it is reduced as analysis of features has resulted in more detailed requirements. The approach assumes that the organization conducting the estimation exercise does not have reliable historical data that can be used to derive the estimates. A case study is presented that describes a pilot conducted in an ABB Unit where the method has been implemented. This paper also shows how key estimation principles have been incorporated to the methods discussed to form a comprehensive estimation process. By implementing the methods and key principles described in this paper, an organization can begin storing reliable historical data for future use. Judgment-ba sed and model-based methods are used to derive size and effort estimates. The paper shows that using different estimation methods helps the project manager to gain better insight on the estimates and obtain a composite estimate that is more robust and reliable. (More)
