What process optimization, continuous improvement (CIP) and process design have in common is that they are all about making processes and services successful.
The difference is like that between renovation and new construction.
While process optimization and CIP assume that the substance is in order and can be saved, process design involves completely new thinking.
Either because there are no foundations yet, or because the existing structure needs to be fundamentally changed.
Process optimization focuses on quick wins and achieving improvements of around 3-5%.
Process design can deliver double-digit improvements or even 3 to 10 times better results through redesign.
