In this study, the Bessant’s Continuous Improvement (CI) Maturity Model, as a means to measure the presence of continuous improvement culture, was tested for its validity and reliability in the context of Malaysian manufacturing companies. The CI Maturity Model has been validated in several different settings before but has yet to be investigated for its applicability in Malaysian manufacturing companies. A total of 321 survey responses were obtained and later analysed by exploratory factor analysis (EFA) and confirmatory factor analysis (CFA). The findings confirmed that the CI Maturity Model showed adequate validity and reliability in the context of Malaysian manufacturing companies. The CI Maturity Model can be used by Malaysian manufacturing companies as a framework for developing continuous improvement culture.
