Purpose: - Kaizen in construction is a new paradigm stemming out of lean production systems. Construction companies in developing economies, such as Nigeria, have a task to innovate to liquidate in certain cases. With the aid of kaizen, which encompasses the benefit of stakeholder relationship improvement and management, profitability enhancement and delivery of projects to satisfied clients, construction companies can realise expected growth. An exploration of the critical success factors and associated drivers within the limits of the scope is essential. Methodology: Exploratory factor analysis statistical tests categorised the critical success factors identified in the literature review section. A detailed sampling approach extracted 135 questionnaires under the 5-point Likert scale format from a larger population in Nigeria. An exploration of important drivers and iteration of eigenvalues combined with asymptotic significance of the drivers provided the critical success factors and significant drivers. Findings: Construction management function (CMF), operational efficiency (OE), construction business ethics (CBE) and construction cost management (CCM) were the critical success factors established from the exploratory factor analysis tests. It was confirmed that kaizen can be adopted in Nigerian construction companies with reflections on the principal drivers for the critical success factors. Practical implications: The exploration of the critical success factors and drivers associated with kaizen implementation can be applied to other developing countries with considerations of implementation in terms of cost and time. Originality/value: The identification of critical success factors provides ample opportunity for consideration of kaizen in construction companies. The findings of this study are a basis for investigations into cost and time implications of kaizen adoption in construction companies.
