Lean concept emerged from the Japanese auto industry as a new process oriented method centered on optimal resource usage and waste elimination. Various researchers have tried to study lean implementation in different manufacturing environments all around the world. Over 50 medium and large Nigerian manufacturing companies were randomly selected to evaluate the level of use of lean tools in Nigeria. Data collection is via 5-point Likert scale questionnaires that were administered to key quality and production personnel in these organizations. Simple descriptive analysis indicates usage of lean tools is skewed towards Kaizen, Just in Time (JIT), and Failure Mode Effect Analysis. Others (Kanban, Jidoka, and Value Stream Mapping) enjoyed significant usage in the companies surveyed.
