Estimointiprosessit, also known as estimation processes or estimation procedures, refer to the systematic and structured approaches used in project management, software development, and other fields to estimate the time, cost, and resources required to complete a task or a project.

The estimation process typically involves identifying the scope and complexity of the task or project, gathering historical data and past experiences, and using mathematical models and statistical techniques to arrive at a reasonable estimate. Estimation techniques can be broadly classified into three types: analogue estimation, parametric estimation, and three-point estimation.

Analogue estimation involves comparing the task or project to similar past projects or tasks, and using historical data to make an estimate. Parametric estimation, on the other hand, uses statistical models and algorithms to estimate the time and cost required to complete a task or project. Three-point estimation involves using three different estimates (optimum, pessimistic, and most likely) to create a probability distribution and estimate the range of possible outcomes.

Estimation processes are an essential part of project management, as they help to establish realistic expectations, allocate resources, and make informed decisions. Effective estimation processes can also help to reduce uncertainty, improve communication among stakeholders, and increase the probability of project success. In addition, estimation processes can be used to identify potential risks and Schedule Cost Variance issues early in the project, allowing project managers to take corrective action and minimize their impact.

Overall, estimation processes play a crucial role in modern project management, and their effective application can lead to improved project outcomes and reduced risk.
