Graph-Based Software Process Management

Software process dynamics challenge the capabilities of process centered software en gineering environments Dynamic task nets represent evolving software processes by hierarchically organized nets of tasks which are connected by control ow data ow and feedback relations Project managers operate on dynamic task nets in order to as sess the current status of a project trace its history perform impact analysis handle feedbacks adapt the project plan to changed product structures etc Developers are supported through task agendas and provision of tools and documents Chained tasks may be enacted in parallel simultaneous engineering and cooperation is controlled through releases of document versions Dynamic task nets are formally speci ed by a programmed graph rewriting system Operations on task nets are speci ed declaratively by graph rewrite rules at a high level of abstraction Furthermore editing analysis and enactment steps which may be interleaved seamlessly are described in a uniform formalism
