Written procedures gather, record and analyse positive and negative customer feedback through surveys, feedback cards, a complaints register or reviews posted online; every complaint is logged, investigated and corrected with actions tracked to closure; satisfaction results are analysed against the Policy, Statement and targets and reported to management; and records of feedback, complaints, actions and improvements are kept for at least three years.
This control maps to 1 controls across 1 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 1 it maps to, and the evidence behind each claim, over MCP and REST.
