The path to operational excellence: Implementing Kaizen principles for competitive advantage. A multiple case study

Abstract

Purpose: This study aims to examine the practical application of Kaizen philosophy and its relevance to strengthening organizational competitiveness in Colombian companies from different industrial sectors.

Design/methodology/approach: The research adopts a multiple case study approach to evaluate the maturity level of Kaizen principles—creating customer value, flow optimization, Gemba orientation, people empowerment, and scientific transparency—using the Kaizen Maturity Model (KMM).

Findings: The results reveal the levels of implementation and main challenges faced by each analyzed organization. A detailed diagnosis and practical recommendations are provided for improving operational efficiency and fostering a culture of continuous improvement.

Research limitations/implications: This study focuses exclusively on Colombian companies, which may limit the generalizability of the findings to other contexts or regions. Future research could explore the application of the Kaizen Maturity Model in a broader range of industries and geographical areas.

Practical implications: The article offers a benchmarking tool based on the Kaizen Maturity Model (KMM) to help companies identify and address gaps in their operational processes, ultimately facilitating their journey toward operational excellence.

Social implications: By fostering a culture of continuous improvement, the adoption of Kaizen principles can contribute to enhanced organizational efficiency, employee empowerment, and better alignment with societal expectations of sustainable and ethical business practices.

Originality/value: This study provides a novel application of the Kaizen Maturity Model (KMM) in Colombian companies, delivering actionable insights and practical recommendations to emulate the efficiency and adaptability exemplified by Toyota.
