In project management, cost and schedule estimation refers to the practice of projecting the amount of time and money required to accomplish a project. This process entails identifying and assessing all essential tasks, defining the resources (e.g., people, materials, equipment), and estimating the duration of each activity. The information gathered
Parametric estimation is a project management technique that uses statistical data and mathematical models to estimate the cost and duration of a project. It is based on the idea that many project characteristics can be described and predicted using statistical data and that a mathematical model can be used to
Bottom-up estimation, also known as detailed estimation, involves breaking down a project into smaller tasks or activities, and then estimating the time and resources required for each task. This approach allows project managers to estimate the cost and duration of the project by summing up the estimated costs and durations
Analogous estimation, also known as top-down estimation, is a project management technique that uses historical data from similar projects to make an estimate for the current project. This approach involves identifying a previous project that is similar in scope, size, and complexity to the project is estimated, and then using

An iterative planning technique, a form of progressive elaboration, in which the work to be accomplished in the near term is planned in detail, while the work in the future is planned at a higher level This method is typically used for projects with a high degree of uncertainty, such
Progressive elaboration is a project management technique used to gradually increase the level of detail in a project plan as more information becomes available. It is closely related to the rolling wave planning method, and is often used in conjunction with it. The technique involves starting with a high-level plan
