VTT PUBLICATIONS 695 Towards a Framework for Improving Software Development Process Mediated with CMMI...

same time, agile methods continue to gain popularity due to increasing speed and quality demands. It has been argued that the CMMI model is too heavy­weight for software development projects adopting agile practices and that its use would lead to an overly document­driven software development approach. This presents a challenge to enable organizations, relying on CMMI as an indicator of process maturity, to also benefit from using agile methodologies such as XP and Scrum. The purpose of this thesis is to increase understanding of how to improve the software development process mediated with the CMMI and the agile practices. The work was done empirically in 4 companies and based on 6 scientific research papers, written jointly with an international group of researchers and published in well­established peer­reviewed scientific fora. In order to answer the gaps in the current empirical body of knowledge and research this study introduces a framework, based on a hybrid assessment approach, and starts the evaluation of the impact of agile practices from the communication perspective. The framework can be used to identify the agile practices for a plan­driven software development process and to validate the software development process against CMMI goals and agile practices.
