The process of adding all the individual component costs together to create an overall budget. Initially it is unlikely that all the candidate features or stories for the project will be identified. So merely adding the estimates for the known stories together will give an estimate that is unreasonably low.  Initial estimates should be based more on traditional estimation approaches (like expert judgement, comparison to other systems, etc) or calculated from Timeboxed project burn projections if a fixed end date must be met.

My first real article was called “What has Leadership got to do with Agile Project Management?” My argument was that effective agile project management was much closer to leadership than traditional project management. It emphasized people over tasks, empowerment over control, effectiveness over efficiency, and direction over speed.
