Hybrid Requirement Elicitation Techniques with Lean Six Sigma Methodology for an Enhanced Framework

Abstract

Requirement Elicitation (RE) is the most important phase in software development life cycle. It is a complex process because it involves the communications between two group of people to get into understanding of what to be built and what need to be delivered from software perspective. The purpose of this paper is to introduce a hybrid framework which combine the RE techniques from analytical and synthetic category with Lean Six Sigma (LSS) method, aimed at improving RE process to produce a quality software requirement. A framework consists of three phases; design, implementation and analysis are proposed where an industry case study is demonstrated for validation. The new framework observed a significance acceptance by analysts where the new hybrid approach is easy to adopt though at absence of users at the early stage of requirement study. The result also shown that the entire RE process cycle time improved tremendously. The limitation of this paper because it only tested in one company and at a specific project. The main contribution of the paper is to provide new knowledge in combining the RE techniques with LSS at absence of end user.
