Abstract: Software cost estimation (SCE) remains one of the most critical yet error-prone activities in software project management. Inaccurate estimates contribute directly to schedule overruns, budget inflation, and diminished stakeholder satisfaction. Simultaneously, the 5S methodology — originating in Japanese manufacturing lean practices — offers a structured approach to workplace organisation, waste elimination, and continuous process improvement. This paper proposes and evaluates a novel framework that integrates the five 5S principles (Seiri, Seiton, Seiso, Seiketsu, and Shitsuke) with established software cost estimation techniques including COCOMO II, Function Point Analysis (FPA), and Use Case Point (UCP) methods. A controlled empirical study was conducted across fifteen mid-scale software development projects in the information technology domain. Projects were monitored over a twelve-month period, with quantitative metrics collected at each software development lifecycle (SDLC) phase. Results demonstrate that 5S integration reduces the Mean Absolute Percentage Error (MAPE) in cost estimation by an average of 62.3%, decreases rework rates from 34% to 6%, and improves the documentation quality index from 42 to 91 on a normalised 100-point scale. The findings provide practitioners and researchers with a reproducible, phase-aligned integration model that bridges lean manufacturing principles with software engineering processes. |
