lean thinking
socio-technical operations management system by which the main objective is to eliminate waste and maximize value (to the customer).
The continuous process improvement cycle consists of four steps. Please use the drop down menu to identify the correct step in the cycle for each continuous improvement action: Do - make the improvement. Plan - identify a process improvement. Act - implement the improvement into the process. Check - examine feedback and adjust improvement as necessary.
