Rapidly changing market conditions, new technologies, short time-to-market cycles and many other factors of the social and business world influence how projects are managed [1]. Different types of projects require different procedural models for successful execution. A procedural model organizes the methods and tools of project management into project phases or processes in a standardized manner. Procedural models for project management can be roughly divided into (1) plan-driven methods. which follow a classical waterfall process; and (2) agile methods (such as Scrum and Kanban), which follow an iterative, test-driven approach [2, 3, 4]. In classical project management following a "waterfall" process of planning and execution, expected results are communicated relatively clearly by the client at the beginning of the project [5, 6]. So that the project can be "worked through" in a goal- and plan-oriented manner, it is planned holistically, from kick-off to completion, with work packages, responsibilities, and deadlines. The focus is on implementing the initial plan as precisely as possible. This provides stability and structure, predictable resources, and documented planning
