Assessing CMMI Level 3 Adoption: Interview and Survey Based Evidence from IT Organizations

Abstract

Objective: This study assesses the adoption of Capability Maturity Model Integration (CMMI) level 3 by IT companies in Bangalore, with a focus on the challenges, benefits, and best practices for implementation.

Methods: Solution architects, quality leaders, project managers, and compliance officers were interviewed using semi-structured interviews (N = 10) and survey (N = 14). Interview responses were subjected to thematic analysis while survey data provided quantitative insights into implementation problems, training effectiveness, and process improvement.

Results: 42% of the thematic analysis-based responses mentioned employee resistance as a major challenge, 29% had issues with process standardization, and 25% cited insufficient training. However, 37% reported improved software quality, and 29% noted higher employee engagement post-implementation. Organizations that used formal change management and role-based training experienced smoother CMMI implementations and long-term benefits. Survey data, while differing slightly in percentages, aligns with these qualitative themes, reinforcing key challenges and adoption trends.

Conclusion: Despite initial resistance and documentation overhead, the use of CMMI Level 3 resulted in improved project predictability, reduced defects, and enhanced customer satisfaction. The study provides practical recommendations to organizations aiming to balance process discipline with business agility while maintaining a culture of continuous improvement.
