When there have been significant corrective action decisions the reasoning behind the decision should be documented in the lessons learned documentation. What is lessons learned documentation? Lessons learned documentation is prepared to contribute to the lessons learned knowledge database of the organization. It includes the causes of issues, the reasoning behind the corrective action chosen, and other types of lessons learned about stakeholder management. Lessons learned are documented so that they become part of the historical database for the project/program and the performing organization. The lessons learned are compiled, formalized, and stored through out the project's/program's duration.

Answer option C is incorrect. A variance report may be appropriate but cost and schedule variances are reported differently. Kay could create a cost variance report and a schedule variance report, but not one report for both project attributes.

Answer option B is incorrect. An exceptions report is the same as a variance report. Kay would create a separate exceptions report for cost, and another for schedule.

Answer option D is incorrect. The information may go into the project final report but it should be included in the project's lessons learned information when it is discovered.
