Comparative Study between Lean Six Sigma and Lean-Agile for Quality Software Requirement

Abstract

Requirement Elicitation is one of the challenging phases in the entire software development life cycle. It is the process of extracting and analyzing the requirements from customers to understand thoroughly of what system needs to be built. Despite all the advances in methodologies and practice approaches, extracting and establishing the right requirements are still part of the research debate. The objective of this paper is to compare the characteristics of two hybrid development approaches; Lean Six Sigma vs. Lean Agile. Most of the comparative studies done by most of the research compared within its relative knowledge such as; Lean vs. Six Sigma, Define-Measure-Analyze-Improve-Control vs. Design-For-Six-Sigma or Lean vs. Six Sigma vs Lean Six Sigma. Whereas in software industries, the comparative studies were focused on Lean vs. Agile, Agile vs. Waterfall, Lean vs. Kanban vs.Agile, which compared the project size, process cycle time, sequential or iterative process. The following parts of the study is to explore the differences and similarities in principles and practices. The study contributes significantly to the business analysts to systematically address the solutions and actions to ensure continuous improvement in producing quality software requirement.

Quality system as a mediating variable of the relationship between lean manufacturing and operational performance in the food industry

“…H2: LM has a positive effect on QS [13]. H3: QS has a positive effect on OP [23,24,25]. This study focuses more on the comparative effect of the three variables, namely LM on OP with QS mediation if applying the LMQC and QSQC methods.…”

Performance Analysis of Family Welfare Empowerment Application: A Kanban Method Approach

“…The findings of this research can offer practical guidance for application developers and practitioners seeking to harness the potential of the Kanban method to enhance testing performance in family empowerment applications. By pinpointing areas of testing efficiency and inefficiency [33], this study equips developers with a roadmap to optimize their testing procedures and streamline workflows, ultimately improving the quality and user experience of these applications. It also underscores the importance of iterative development and real-time monitoring facilitated by Kanban [34], enabling practitioners to adopt a more adaptive and responsive approach to application development.…”
