A Fine-grained Process Modelling Experiment at British Airways

We report on the experimental application of process technology that we did at British Airways #BA# as part of the GOODSTEP project. The goal of GOODSTEP was to enhance and improve the functionality of an object database management system #ODBMS# to yield a platform suited to the construction of process-centred software engineering environments #PSEEs#. These enhancements were exploited and validated by the construction of the GOODSTEP framework for PSEE construction, which includes the SPADE software process toolset. We used the process modeling language SLANG to model BA's C++ class library management process, and we constructed an experimental PSEE based on SPADE. BA required processes to be automated at a #ner degree of granularity than that of tool invocation. Wehave demonstrated that SLANG and SPADE o#er the basic mechanisms for modelling these #ne-grained processes. Wehave also shown that it is feasible to generate tools for dedicated processes and integrate them with..

Syntax Graph implement syntactic relationships, and referenceedges, which arise from semantic relationships. Documents are identi#ed by the subgraph whose node-set is the transitive closure of nodes reachable by aggregation edges from document root nodes. Nodes that cannot have out-going aggregation edges are called terminal nodes, for they are derived from terminal symbols of the underlying grammar. Those nodes that mayhave out-going aggregation edges shall be called non-terminal nodes
