BottomupSchätzung

BottomupSchätzung, also known as bottom-up estimating, is a project management technique used to determine the time, cost, or resources required to complete a project. It involves breaking down a project into smaller, more manageable tasks or work packages. Each of these individual components is then estimated separately. These individual estimates are then aggregated or summed up to arrive at an overall project estimate.

This method relies on detailed knowledge of the individual tasks and the resources or effort needed for each. It often involves input from the people who will actually perform the work, as they have the most accurate understanding of the effort involved in their specific tasks. The advantage of bottom-up estimating is its potential for high accuracy, as it is based on granular details. However, it can be time-consuming and requires a well-defined project scope and detailed task breakdown. It is particularly useful for projects where tasks are clearly defined and there is a good understanding of the work involved at the lowest levels. When used effectively, it can lead to more realistic and achievable project plans.
