Item INTEGRATING LEAN SIX SIGMA WITH AGILE SOFTWARE DEVELOPMENT METHODOLOGY(2022-02-16) Badwe, Safia; ERKAN, Turan ErmanIn the last two decades, the Six Sigma approach has also experienced extended introduction into the software development industry, with lean thinking emerging as a new paradigm to make the process more efficient. Some software companies have been trying to adapt Six Sigma and Lean for their business and development initiatives. Lean Six Sigma (LSS) accelerates the test and reconciliation aspects of item advancement and makes room for providing top-notch products to purchasers. Still, a need for constant change and transformation has forced organizations into adopting to complex and new working environments, resulting in software development methodologies to become a framework for planning and coordinating programs and communicating with customers so as to collect the requirements. In this respect, LSS and Agile methodologies are regarded as a set of development initiatives to satisfy such demands at an early stage and incorporate high-quality changes into the software development process; hence the present study explores the relationship between the methodologies mentioned above in software development. This research presents the results from a theoretical and empirical part. The first part is to introduce a model that combines the operational stages to examine Six Sigma, Lean, Lean Six Sigma, Agile and Scrum methodologies to try and devise a new approach called ‗LSS-Agile‘ methodology. The second part presents the results of a survey study conducted with practitioners of software development companies in Turkey and abroad. The questionnaire focuses on several aspects, most importantly: benefits implementation, critical success factors, satisfaction, change requirements, experiences, and problems faced when using methodologies. The empirical perspective is analyzed by developing hypotheses about the concepts and factors on the study of methodologies and their impact on software development. The results highlight the most important factors leading to the success and failure of software development as well as the most beneficial aspects of the performance of methodologies. To this end, the analysis of the Lean Six Sigma and Agile methodology, their interrelationships helps to better understand the idea of integrating the two. As a comparisons carried out between a number of Turkish and Canadian companies specializing in this field, the results confirm that Turkish companies in the software development sector entered the world market from the widest successfully and have become one of the most competitive countries in this field.
