Business Process Aware IS Change Management in SMEs 39 Pattern Extsend is similar to Pattern Extrec. The difference is that BP receives new activities instead of handing them over. Knowledge is to be received together with the activities and data about activities sent to the process from which the activities were received, or new users added to IS. While a particular sequence of events was used in the aforementioned pattern descriptions, it characterizes only one possible sequence of events inside the pattern.
These sets of changes may be used as patterns for situation analysis to anticipate full range of activities to be performed to get the business process and/or information system back to the stable state after it is lost because of the changes in one of the elements. Knowledge about the change pattern gives an opportunity to manage changes of information systems even if business process models and information systems architecture are not neatly documented as is the case in many SMEs. Using change patterns it is possible to know whether changes in information systems are to be expected and how changes in information systems activities, data and users will impact different aspects of the business process supported by the information system.
The use of this sub-graph for verification of an ECAPE process is backed by the fact that this latter represents how the process rules set is activated. As a result, a cause/effect subgraph formalizes the process functioning. For illustration purposes we adopt the live-lock case. This case occurs if a sub set of rules behave like an infinite loop, which puts a process in an endless state. This could be due to a poor analysis of the rules that are executed. B), then the new rule R9 will rerun the process by activating rule R2.
