Editing Critical path method (section)

=== Flexibility ===
A schedule generated using the critical path techniques often is not realized precisely, as [[Estimation (project management)|estimations]] are used to calculate times: if one mistake is made, the results of the analysis may change. This could cause an upset in the implementation of a project if the estimates are blindly believed, and if changes are not addressed promptly. However, the structure of critical path analysis is such that the variance from the original schedule caused by any change can be measured, and its impact either [[:wikt:ameliorated|ameliorated]] or adjusted for. Indeed, an important element of project postmortem analysis is the 'as built critical path' (ABCP), which analyzes the specific causes and impacts of changes between the planned schedule and eventual schedule as actually implemented.
