A compliance obligation register catalogs every requirement an organization must fulfill, mapping obligations to responsible owners, applicable business units, evidence sources, and monitoring frequencies. This living document includes statutory regulations, industry standards, contractual commitments, voluntary frameworks, and internal policies. A healthcare provider's register might span HIPAA, FDA regulations, Joint Commission standards, payer contracts, and internal ethics policies. Registers prevent compliance gaps by ensuring systematic identification, interpretation, and assignment of obligations. Effective registers integrate with control frameworks, audit schedules, and change management processes to maintain currency as regulations evolve and business operations expand.
