Therefore, the process needs to be changed and all the related documentation, deployment, and testing must be repeated It also means that you could end up with a very large process Business processes as components An alternative, more modular approach to solving the problem described above is one where a business service interface "stands in"for one of many compatible processes(compatible, meaning that they have the same interfaces). A single process can then be dynamically selected at execution time. See Figure 2 Figure 2.
