Graph-Based Software Process Management

Abstract

Software process dynamics challenge the capabilities of process-centered software engineering environments. Dynamic task nets represent evolving software processes by hierarchically organized nets of tasks which are connected by control, data, and feedback flows. Project managers operate on dynamic task nets in order to assess the current status of a project, trace its history, perform impact analysis, handle feedback, 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 executed in parallel (simultaneous engineering), and cooperation is controlled through releases of document versions. Dynamic task nets are formally specified by a programmed graph rewriting system. Operations on task nets are specified declaratively by graph rewrite rules at a high level of abstraction. Furthermore, editing, analysis, and execution steps on a dynamic task net, which may be interleaved seamlessly, are described in a uniform formalism.

Model-Driven Software Development with Graph Transformations: A Comparative Case Study

“…They were described earlier, e.g. in [11]. For this case study, we considered a "light" version of dynamic task nets which comprises only some of the core concepts.…”

ProActNet: MODELING PROCESSES THROUGH ACTIVITY NETWORKS

“…Therefore, incremental process program development is supported. Moreover, UML based diagrams have been added to facilitate process analysis [17,18].…”

“…An activity involves workers (e.g., analysts and programmers) to produce products (i.e., software products such as specifications and program code) using tools (e.g., the rational ROSE [4]). Many process-centered software engineering environments (PSEEs) [5][6][7][8][9][10][11][12][13][14][15][16][17][18] have been developed to facilitate managing complicated processes. Generally, a PSEE provides a process modeling language to model processes as process programs for enactment.…”

Ein graphbasiertes Managementsystem für dynamische Entwicklungsprozesse

“…9). Dies ist auch im EPOS-System [28] [24,41,68]. Während im Bereich der Graphgrammatiken und Graphersetzungssysteme eine Fülle von theoretischen Ansätzen existiert [55], wurden die praktischen Anwendungen lange vernachlässigt, finden jedoch zunehmendes Interesse [12].…”
