Due to a strategic realignment in 2025, Coop’s Workflow Product Team was downgraded to priority level 3, resulting in a drastic reduction in development resources. The rigid Scrum framework proved unsuitable for the now predominantly maintenance-oriented operations. In addition, there was no structured decision basis for selecting the optimal agile method for each project context.

The thesis combines an extensive literature review of Scrum, Kanban, and Scrumban with qualitative expert interviews within the Workflow Product Team. From theory and practice, 25 decision criteria were derived and consolidated into a structured decision tree. This was implemented as a visual Confluence version, integrated into Coop ChatAI, and deployed as a no-code prompt application to interactively support teams in method selection.

The study shows that no single agile method is universally optimal: Scrum offers structure, Kanban maximum flexibility, and Scrumban combines both. The developed decision-making guide enables Coop teams to select the appropriate method based on 25 clearly defined criteria such as team availability, task complexity, delivery cadence, and governance requirements. For the Workflow Product Team, adopting Scrumban led to greater flexibility, reduced meeting load, improved prioritization, and clearer decision processes. In the long term, the guide can be applied across the organization to make methodological decisions transparent, reproducible, and strategically aligned. This increases efficiency, reduces uncertainty, and supports alignment with corporate goals.
