Projektinhallintamallit, or project management models in English, refer to the systematic frameworks and methodologies used to plan, execute, and close projects. These models provide a structured approach for managing time, cost, scope, quality, and stakeholder expectations. Common elements across models include project initiation, planning, execution, monitoring, and closure, though each model may emphasize different aspects or processes.

Traditional models such as the Waterfall or the Critical Path Method (CPM) rely on sequential phases with defined deliverables. In Waterfall, each phase—requirements, design, implementation, verification, and maintenance—is completed before the next begins, making it suitable for projects with well‑defined outcomes. CPM focuses on sequencing tasks and identifying critical activities that determine the project’s overall duration. In contrast, agile models like Scrum, Kanban, and KanbanFlow prioritize iterative development, frequent feedback, and adaptability. Scrum divides work into sprints with daily stand‑ups, while Kanban visualizes workflow on a board, encouraging continuous delivery.

Hybrid approaches blend predictive and adaptive elements to suit complex environments. For instance, the PRINCE2 framework incorporates stage gates and product focus, allowing flexibility within a controlled process. The Lean‑Six Sigma model combines lean principles of waste reduction with Six Sigma’s data‑driven quality improvement.

Choosing a model depends on project characteristics such as size, risk, stakeholder involvement, and regulatory constraints. Effective application requires trained personnel, clear documentation, and appropriate tools for collaboration, risk tracking, and performance measurement.
