PMkaava

PMkaava is a term used in Finnish project management literature and practice to refer to mathematical formulas applied in planning, budgeting, and scheduling of projects. It is not a single standardized formula; rather, PMkaava describes a family of formulas that organizations apply within templates, software, or training materials to estimate effort, cost, duration, and resource needs.

Usage and scope: The term appears in educational contexts, consultancy materials, and corporate templates. Different organizations may define their own PMkaava variants tailored to their methods, tools, and industry contexts.

Common variants: In cost estimation, a typical PMkaava might be Total Cost = Fixed Cost + (Unit Cost × Quantity) + Contingency. In scheduling, PMkaava variants may express Duration as Duration = Work / Productivity, or use related formulations for man-hours, staffing levels, and task duration. In risk-aware planning, PMkaava can include a multiplier for risk or uncertainty.

Application: To apply a PMkaava, a planner collects the relevant inputs (scope, quantities, unit costs, productivity rates), selects an appropriate variant, computes the result, and then reviews the output for plausibility. The approach is often iterative and used in combination with other planning tools.

Limitations: PMkaava-based estimates rely on input accuracy and chosen assumptions; they can oversimplify complex dependencies or external factors. They are best used as planning aids rather than precise forecasts.
