Integrating Lean Principles with Value Based Software Engineering

Lean Six-sigma principles and methods have been successfully applied in a variety of industries. Many of the core principles of Lean Six-sigma can be applied to software development to dramatically improve performance with some industry specific adaptations. In this regard, Lean Six-sigma principles can be made to further leverage the benefits of software engineering best practices to improve work flow and the tactical management of the project. The Value Based Software Engineering (VBSE) process as practiced today, begins the software development lifecycle (SDLC) with a sophisticated customer value analysis (CVA) which is coupled with a quantitative evaluation of pricing and profitability options followed by development of the software. The CVA yields a wealth of information not only for product features, but also for improving all processes within the organization that touch the customer. This paper seeks to present and articulate how applicable Lean Six-sigma principles can be coupled with the VBSE to improve the SDLC by improving the identification and delivery of customer value as well as the reduction of wasted resources. The net result is to substantially enhance the VBSE SDLC and the the organization's overall ability to deliver value.
