Analysing how legislative and regulatory frameworks inform quality standards that apply to the work setting is about the legal responsibility for making sure areas of your service are up to standard. For example the CQC Fundamental Standard Regulation 17 is all about having processes etc in place to continually monitor ( & respond) to auditing areas of the service. Look this Regulation up as this might help. Also of course there is Health & Safety legislation so this would include safety in the service, tests/servicing equipment, medication audits, staff audits etc.
