18、between redesigning an existing process and designing a new currently non-existing process In both cases we need to understand the purpose of the process and what the customers desire from it If the process exists, we need to understand what it is currently doing and why it is unsatisfactory Busines

How well does it perform? What are the critical issues that impact the pr

The redesign team must understand the process but should not overanalyze it in order to avoid “analysis paralysis” Becoming so familiar with the process it is impossible to think of new ways of doing it Essential activities for building process understanding Configure the redesign

What do they do with the process output?The ultimate goal with a business process is to satisfy the customers real needs in an efficient way!,18,Creative Process Design (I),Designing new processes is more of an art than a science Cannot be achieved through a form

27、alized methodMost existing processes were not designed; they just emerged as new parts were added iteratively to satisfy immediate needsThe end result of any design is very much dependent on the order in which information becomes available Inefficient processes are created when iterative design meth
