Before a process can be improved it must be fully understood and characterised.
The process must be mapped end-to-end, i.e. from first customer contact to delivery of the product or service. This is always a manual, group activity.
Similarly the improved process - the Future State - should be mapped in detail before implementing the improvements.
It is imperative that the impact of the changes on any other processes sharing the same resources are explored.
While maps should be created manually, there is significant benefit in using mapping software to store and maintain maps and to manage change. Sherpa will advise you and assist with implementation.
