First things first – make sure that there is both a mandate, and funding, for the work you are doing. If you require the support from within your company to get started with BPM, you should concentrate on building a business case for your BPM initiative first.
Even when the process is being automated without major changes to the way work flows through the company, the users themselves will experience a disruption. BPM always represents a new way of doing things. Therefore, both business managers and end users need to recognize the problems with the existing process and have a desire to fix them.
