Project estimation is one of the first steps in project management. Project estimation is the process of forecasting, or estimating, the resources, time, and cost of completing a project. Project estimation techniques are used in project management during project initiation, in the planning phase. ...

3. Use the bottom-up approach when estimating timelines While the phase-service-task breakdown is often sufficient for many projects, thebottom-up approachis handy for complex or unfamiliar projects. This involves starting with the smallest units of work—individual tasks—and building up to the o...

3. Bottom-Up and Top-Down Estimating Bottom-up estimating is breaking down large tasks into smaller, more detailed tasks. Then you estimate how much time it will take to complete each task. Estimating time at a granular level also increases accuracy. ...

Top-down estimating: This estimation technique takes a broad look at the project as a whole, then breaks the total estimate down into major phases of work. It’s typically used when you have limited information about the project to work from. Bottom-up estimating: The bottom-up approach is...
A project cost breakdown is the process by which a project manager estimates what will need to be spent in order to deliver a project. A cost breakdown structure is used during the project cost estimating process to ensure all costs are accounted for in thecost management plan. ...
