Flexibility as a Service
The lack of flexibility is often seen as an inhibitor for the successful application of work flow technology. Many researchers have proposed different ways of addressing this problem and some of these ideas have been implemented in commercial systems. However, a \"One size fits all\" approach is likely to fail because, depending on the situation (i.e., characteristics of processes and people involved), different types of flexibility are needed. In fact within a single process/organization varying degrees of flexibility may be required, e.g., the front-office part of the process may require more flexibility while the back-office part requires more control.
