Business Process Support - from Initial Analysis to Introduction into Operational Practice (Obstacles to Overcome)

There is an important difference between a traditional business application and a business process support (BPS) system. A traditional business application is aimed at supporting the old way of doing business but more effectively. A BPS system can be considered as a tool of introducing a new way of organizing work. Moreover, this way is often impossible to introduce without a support system. This difference affects all stages of system development, from initial analysis to introduction into the operational practice. For example, what are the best ways to discuss with domain expert a new way of organizing business before you have any system? In what way the user can recognize in the system the requirements created during the analysis phase? How much of the system should be initially introduced in operational practice so that the user can get a "feeling" of the new way of organizing business and accept it? A list of these, and other questions are being put forward for brainstorming.
