Comparative Analysis of Software Process Improvement Models

Abstract

This paper presents a comprehensive comparative analysis of four leading process improvement models: CMMI, ISO, Lean and Six Sigma. The objective is to evaluate and compare these models to determine their effectiveness in optimizing organizational processes. Using a qualitative method of analysis, the study breaks down each model based on standardized criteria, including complexity of implementation, performance metrics, and applicability across industries. The results highlight the unique strengths and limitations of each model and provide a nuanced understanding of their operational impact. The study provides a detailed guide for organizations to select an appropriate model tailored to their specific process improvement needs
