How to improve software development process using mathematical models for quality prediction and elements of Six Sigma methodology

摘要

In this paper technical cost and financial inputs and outputs will be used as main parameters to propose theoretical model how and where should be main work focus to achieve best financial results. The Six-Sigma methodology was used to prove the models and concept. The paper deals with software quality prediction techniques, different applied models in different development projects and faults existing indicators. Three case studies are presented and evaluated for prediction of software quality in very large development projects within the AXE platform using SIP as a call control protocol in the Ericsson Nikola Tesla R&D.
