The project manager should coach the functional groups on how to properly conduct the process of identifying and categorizing risks, as this will help to improve the quality and consistency of the risk information and to facilitate the development of an effective risk response plan. The project manager should also provide guidance and support on how to use the appropriate tools and techniques, such as risk breakdown structure, risk taxonomy, risk checklists, risk interviews, and risk workshops, to elicit and document the risks from different perspectives and sources. By coaching the functional groups, the project manager can also enhance their risk awareness and ownership, and foster a collaborative risk culture within the project.
