Fine grained Process Modelling: An Experiment at British Airways

By Wolfgang Emmerich, Sergio Bandinelli, Luigi Lavazza and Jim Arlow


We report on the experimental application of process technology at British Airways #BA#. We used SLANG to model BA's C++ class library management process, and we constructedanexperimental process-centred software engineering environment #PSEE# basedon SPADE. BA requiredprocesses to be automatedata #ner degreeofgranularity than tool invocation. We have demonstrated that SLANG and SPADE o#er the basic mechanisms for modelling these #ne-grainedprocesses. We have also shown that it is feasible to generate tools for dedicatedprocesses and integrate them with a SLANG model so as to facilitate #ne-grainedprocess automation. However, our experience highlighted some open problems. For instance, SLANG process models are tuned to e#cient enactment, thus containing very detailedprocess fragments. These are not the most appropriate representation for humans trying to understand the process model. A morecomprehensible notation is needed for design and documentation purposes. Although the airline d..
