Feature Development in BPMN-Based Process-Driven Applications
Schneid Konrad, Thöne Sebastian, Kuchen Herbert
In the context of Continuous Software Engineering, it is acknowledged as best practice to develop newfeatures on the mainline rather than on separate feature branches. Unfinished work is then usuallyprevented from going live by some kind of feature toggle. However, there is no concept of feature togglesfor Process-Driven Applications (PDA) so far. PDAs are hybrid systems consisting not only of classicalsource code but also of a machine-interpretable business process model. This paper elaborates on a featuredevelopment approach that covers both the business process model and the accompanying source codeartifacts of a PDA. The proposed solution, Toggles for Process-Driven Applications (T4PDA), equippedwith an easy to use modeling tool extension, enables the developer to safely commit unfinished work onmodel and source code to the project’s mainline. It will be kept inactive during productive deploymentsunless the feature is finally released. During an AB/BA crossover design experiment, the T4PDAapproach, including the provided tool support, showed higher software quality, a faster developmentprocess, and contented developers.
