Conducting the Post-Implementation Audit

The post-implementation audit is an evaluation of the project's goals and activity achievement as measured against the project plan, budget, time deadlines, quality of deliverables, specifications, and client satisfaction. The log of the project activities serves as baseline data for this audit. The following six important questions should be answered:

1. Was the project goal achieved?
   1. (a) Does it do what the project team said it would do?
   2. (b) Does it do what the client said it would do?

   The project was justified based on a goal to be achieved. That goal either was or wasn't achieved, and the reasons for this must be provided in the audit. This can be addressed from two different perspectives. The provider may have suggested a solution for which certain results were promised. Did that happen? Conversely, the requestor may have promised that if the provider would only provide, say, a new or improved system, then certain results would occur. Did that happen?

2. Was the project work done on time, within budget, and according to specification?

   Recall from the scope triangle discussed in Chapter 1 that the constraints on a project are time, cost, and the client's specification, as well as resource availability and quality. Here you are concerned with whether the specification was met within the budgeted time and cost constraints.

3. Was the client satisfied with the project results?

   It is possible that the answers to the first two questions are yes, but the answer to this question is no. How can that happen? Simple: the Conditions of Satisfaction (COS) changed, but no one was aware that they had. The project manager did not check with the client to see whether the needs had changed, or the client did not inform the project manager that such changes had occurred.

   I remind you again that it is absolutely essential that the COS be reviewed at every major event in the life of the project, including changes in team membership, especially a new project manager, and changes in the sponsor. Reorganization of the company, acquisitions, and mergers are other reasons to recheck the COS.

4. Was business value realized? (Check the success criteria.)

   The success criteria were the basis on which the business case for the project was built and were the primary reason why the project was approved. Did you realize that promised value? When the success criteria measure improvement in profit, market share, or other bottom-line parameters, you may not be able to answer this question until some time after the project is closed.

5. What lessons were learned about your project management methodology?

   Companies that have or are developing a project management methodology will want to use completed projects to assess how well the methodology is working. Different parts of the methodology may work well for certain types of projects or in certain situations, and these should be noted in the audit. These lessons will be valuable in tweaking the methodology or simply noting how to apply the methodology when a given situation arises. This part of the audit might also consider how well the team used the methodology, which is related to, yet different from, how well the methodology worked.

6. What worked? What didn't?

   The answers to these questions are helpful hints and suggestions for future project managers and teams. The experiences of past project teams are real “diamonds in the rough” — you will want to pass them on to future teams.

The post-implementation audit is seldom done, which is unfortunate because it has great value for all stakeholders. Some of the reasons for skipping the audit include the following:
