The plan should set out what quality objectives apply to the specific case and the means of meeting them; they may be set, for example, around the case's quality characteristics, matters that affect whether customers or other interested parties are satisfied, and chances to improve how work is done; they should be measurable.
This control maps to 4 controls across 4 other frameworks. If you already hold one of them, the evidence you collected for it is the starting point here rather than new work.
Every mapping shown was judged rather than inferred from wording similarity, and the ones that failed review are published too. See the coverage reports and what was rejected.
The graph holds this control, the 4 it maps to, and the evidence behind each claim, over MCP and REST.
