User interface derivation for business processes

User Interfaces (UI) are the bridge to connect Business Processes (BPs) and end users. The implementation of UIs normally needs a lot of manual efforts of developers. Aiming to resolve this issue, this work proposes a UI derivation method with a role-enriched BP (REBP) model as its foundation. This process model has the capability to present the details of task control flow and data operations in tasks. A set of control flow patterns and data operation patterns is identified. For each participant role, tasks of a process are abstracted and aggregated, then data relationships are extracted according to the identified control flow patterns and data operation patterns. A set of mandatory and recommended rules has been developed for deriving the UI logic from a BP. The solution for the UI derivation has been provided and implemented in the prototype. This proposed UI derivation method can provide help for the analysis, design, and maintenance of UI components of BPs.
