Estimation of the new agile XP process model for medium-scale projects using industrial case studies

TL;DR

This paper proposes an extended XP agile process model tailored for medium-scale projects with large teams, validated through two industrial case studies, addressing limitations of the traditional XP model.

Contribution

A new XP process model is introduced to better suit medium-scale projects, overcoming traditional XP limitations for larger teams and project sizes.

Findings

Validated through two industrial case studies

Improved documentation and performance for medium-scale projects

Potential for adaptation to large-scale software development

Abstract

Agile is one of the terms with which software professionals are quite familiar. Agile models promote fast development to develop high quality software. XP process model is one of the most widely used and most documented agile models. XP model is meant for small-scale projects. Since XP model is a good model, therefore there is need of its extension for the development of medium and large-scale projects. XP model has certain drawbacks such as weak documentation and poor performance while adapting it for the development of medium and large-scale projects having large teams. A new XP model is proposed in this paper to cater the needs of software development companies for medium-scale projects having large teams. This research may prove to be step forward for adaptation of the proposed new XP model for the development of large-scale projects. Two independent industrial case studies are conducted to validate the proposed new XP model handling for small and medium scale software projects, one case study for each type of project.
