Hoofdfase

Hoofdfase is a Dutch expression used to indicate the main or central phase within a project, process, or lifecycle. The term combines hoofd meaning "head" or "main" and fase meaning "phase," and is applied in contexts where a project’s central activities determine its character and outcomes.

In project management the hoofdfase typically encompasses core design, development, or execution activities, and is usually scheduled after initial feasibility or planning work and before evaluation or completion. It often involves the largest share of resources, coordination across teams, and the achievement of its primary deliverables.

Examples: In construction, the hoofdfase might be the execution stage where construction work takes place. In software development, it can refer to the main development and integration cycle. In research, the hoofdfase may cover data collection and analysis that form the backbone of results.

Usage: The term is context-dependent and not a formal standard term in all fields; some domains prefer "kernfase" or "uitvoeringfase" or simply "de hoofdfase" as a generic label.

In methods and standards, the lifecycle often includes initiation, planning, execution (which can be equated with hoofdfase), and closure; when used, hoofdfase connotes the period with the most substantial progress and risk. See also project lifecycle, phase management.
