Lean production is widely understood to be production based upon a range of waste saving measures inspired by Japanese manufacturing companies‚ particularly the Kaizen and Just in time techniques. Metov’s plastics have taken the decision upon themselves to incorporate some of the characteristics of lean production namely time management and critical path analysis into their manufacturing process and I will examine these. One method used by Metov’s is critical path analysis (CPA). CPA is the process
