No abstract or file available.Lean was first adopted as a management technique for improving results in manufacturing environments. It is based on the 5 principles of identifying the Value to be created, mapping the Value-Stream (incremental addition of value), ensuring process Flow, orienting the process towards the Pull of the customer and finally eliminating all Waste through a process of continuous improvement. This framework is highly adaptable, and has been applied in recent years to non-manufacturing efforts, such as product development and the retail and service industries.
