An Empirical Investigation of Effort Estimation in Mobile Apps Using Agile Development Process

Abstract

Effort estimation is essential in order for a project manager and development team members to be able to successfully plan for a software project. The planning and development of mobile applications present many challenges. The aim of this study is to provide and report an overview on the state of the practice of effort estimation techniques that companies use for their mobile app projects. This study focuses on organisations which apply the Agile development process during their projects. We conducted structured and semi-structured interviews with 20 Agile practitioners at 18 different organisations. The results revealed that Planning Poker (PP) and Expert Judgment (EJ) were the most frequently used estimation techniques in mobile app projects.
