There are standard components to each of the documents you mention: the risk analysis report and the project quality plan. There is a set format for the risk analysis report insofar as each component must occupy its own space in a horizontal analysis grid or a multi-linear Ven diagram, though there is not one single accepted, unvariable, format within these guidelines. There is a set format for the project quality plan insofar as the details of each section must be present and thoroughly discussed with tables clearly presented. From report examples and plan templates I've linked to, you can see that each of these documents requires a different approach and different kinds of displays.
Risk analysis reports must contain relevant information pertaining to risk including;
- Risk assessment
- Risk management
- Risk management process (Edith Cowan University)
Project quality reports must contain relevant information pertaining to setting, managing, assuring and controlling product or project quality, including:
- Quality management approach
- Quality requirements and/or standards
- Quality assurance
- Quality control
- Quality control measurements (ProjectManagementDocs.com)
As long as you select a format in keeping with the standard examples and include all the relevant information (not exclusively detailed here), your report and plan will meet the general format requirements. A good detailed description (beyond the scope of eNotes format and objective) of the requirements for a project quality plan is available from DoIt Project Management of the University of Wisconsin and from TutorialsPoint.com, while a detailed discussion of the requirements for a risk analysis report is available from H. S. Direct of the UK.
