Väliestimointi

Väliestimointi, often translated as intermediate estimation or interim estimation, is a practice used in project management and financial forecasting. It involves the process of re-evaluating the estimated cost, schedule, or resources required for a project at specific points in time, rather than relying solely on the initial estimate made at the project's inception. This re-estimation is typically performed after significant milestones have been achieved or when new information becomes available that could impact the project's overall outcome.

The primary purpose of väliestimointi is to provide a more accurate and up-to-date understanding of the project's status and future needs. By periodically reviewing and adjusting estimates, project managers can identify potential deviations from the original plan early on. This allows for proactive decision-making, such as reallocating resources, adjusting scope, or revising timelines to mitigate risks and keep the project on track towards its objectives. It also aids in financial control, ensuring that budgets remain realistic and that stakeholders are informed of any potential overruns or savings.

Väliestimointi is not a one-time event but rather a continuous process throughout the project lifecycle. The frequency and depth of these intermediate estimations depend on the project's complexity, duration, and the volatility of its environment. In agile methodologies, for example, similar principles are embedded in iterative planning and review cycles. The data gathered from väliestimointi is crucial for performance measurement, trend analysis, and ultimately, for improving the accuracy of future project estimates.
