Abstract
This study investigates lean manufacturing among South African small, medium and micro (SMMEs) manufacturing enterprises based in the Gauteng Province. Lean is widely regarded as a proven productivity improvement methodology; yet, its impact on South African SMMEs remains relatively unknown. The study used a mixed method approach. Survey data was analysed using statistical methods from 32 responses received from SMMEs in various manufacturing sectors. Interviews were conducted with management and workshop employees. The results revealed that most SMMEs experienced short-term successes that did not exceed three years, implying that they failed to sustain the gains of lean manufacturing. Factors found to have a positive impact on the success and sustainability of Lean implementations were change management, adequate budget, resources with appropriate skills, senior leadership commitment, and adherence to an implementation plan. These results contribute to the lean implementation theory and can be used as a guide by lean practitioners.
