Um modelo para estimativa de esforço em projetos de reengenharia de software

Abstract

Effort estimation is in the core of a software development project since it is useful for cost estimation, resource allocation planning, and follow-up of software investment and budget. Given the importance of the area, there are several studies that are mainly concerned on proposing new models and on the use of new techniques to improve the accuracy of estimates or to evaluate the best model to be applied in a given context. In the specific context of software reengineering projects, there is a lack of related work. Indeed, on the contrary of what occurs for the development of new projects, there is very few knowledge on how the effort estimation is done in that type of projects. In this context, this work aims to propose a model to estimate effort in software reengineering, which includes the steps to carry-out for planning, implementation, monitoring and learning of this estimation. This model was proposed based on the related literature, challenges, good practices and lessons learned identified in two empirical studies in the industry. Such studies involved an exploratory field study and a case study in organizations that carry out software reengineering projects.
