doelmark

Doelmark is a term used in discussions of goal-oriented design and performance measurement. It denotes a defined target state or milestone that a system, process, or project is intended to reach. The term combines the Dutch woorden doel (goal) and mark (mark or target), reflecting its emphasis on explicit end states and evaluative criteria.

In practice, a doelmark is expressed as a specification of the end state and often includes qualifiers such as permissible deviation, time frame, and success criteria. Doelmarks can be binary (achieved or not) or graded, with multiple levels indicating varying degrees of attainment. They are intended to provide a clear reference point for assessment and decision-making.

Contexts where doelmarks appear include project management, software development, and education or training. In project management, doelmarks align with milestones and deliverables; in software development, they may define acceptance criteria or quality checkpoints; in learning contexts, they mark levels of competence. In adaptive systems and reinforcement learning, a doelmark can serve as a reward threshold or stopping condition, guiding the agent toward a predefined end state.

Advantages of using doelmarks include clearer expectations, improved progress tracking, and structured decision points. Potential criticisms focus on subjectivity in defining targets, the risk of inflexibility, and the challenge of selecting appropriate levels of granularity. Proponents argue that when well defined, doelmarks enhance transparency and accountability without prescribing all intermediate steps.
