All true agile projects follow the same philosophy, they do not all apply the same set of practices, tools or processes. Agile projects are value driven, thus subject to change. On face value, agile practices decry the need for estimation. If we know the schedule, team size, the release cadence, cost and effort estimation is just math. This of course requires an organization to embrace ‘utopian agile’ practices. Most organizations apply a modified agile implementation, applying many agile best practices while still working within requirements dictated by contracts and acquisition practices.
This presentation displays a methodology and rules of thumb for estimating agile projects at various phases of a project, merging standard estimation practices with knowledge of how some agile practices might influence project cost and effort.
