Cost of change

Figure 1: The cost of change in the lifetime of a project. Red line: in a traditional sequential project, the cost of change becomes increases dramatically as the project progresses. Grey dotted line: the cost of fixing defects is similar. Blue line: the ability to respond to changes goes linear down as the project progresses.

Figure 2: Red line: The cost of change in a traditional sequential project. Blue line: the cost of change in a realistic agile project approach. Grey line: the cost of change ideally in an agile project approach.
