DELAYS
REQUIRES An accepted, simple, as-planned program An as-built program that is very similar, in terms of key sequence, to as-planned program. Does not need to be a program with a critical path, although much more convincing if it is A very convincing narrative or a variation of the methodology that uses timeslices and a critical path that has been determined contemporaneously.
TIME IMPACT A prospective analysis demonstrates the causality of the delaying event, at the time of the delaying event, using a current project program.
PROS
CONS
It demonstrates causation at the time of the delay
Costly and slow to produce, especially if impacting the baseline retrospectively (post-project completion)
Ideally used to demonstrate causation during the project
Requires good supporting, contemporaneous records
Can be used to demonstrate delays (convincingly) after the completion of the project by retrospectively impacting the baseline program contemporaneous program updates
Being a prospective form of analysis, it might not demonstrate the precise, actual delay to completion
Relies on established facts
Some concerns of its suitability in demonstrating delay after the fact when it is a prospective form of analysis.
Best method of analysis during the project The chain of causation is satisfied Allows for changes to logic, durations, and the critical path Progress and concurrency are considered.
