Managing conflict, implementation and post completion
Post-completion audit (PCA)
5.1 Definition
'An objective independent assessment of the success of a capital
project in relation to a plan.'
5.2 Scope and purpose
To identify causes of variances from budget and general lessons to be learned.
Often carried out by small teams, typically consisting of an accountant and an
engineer who have had some involvement in the project.
Not common to find PCA as the responsibility of internal audit.
5.3 Benefits of post-completion auditing
It improves the quality of decision making by providing a mechanism whereby
past experience can be made readily available to decision makers.
It encourages greater realism in project appraisal by providing a mechanism
whereby past inaccuracies in forecasts are made public.
It provides a means of improving control mechanisms by formally highlighting
areas where weaknesses have caused problems.
It enables speedy modification of under-performing/over-performing projects by
identifying the reasons for the under or over performance.
It increases the frequency of project termination for ‘bad projects’.
It highlights reasons for successful projects which may be important in
achieving greater benefits from future projects.
