BCMS performance indicators

Answer: At this moment we do not have specific examples of performance metrics for a BCMS, but I suggest you to take a look at this article so you can have ideas from an ISMS perspective that can be adapted to a BCMS:
- Key performance indicators for an ISO 27001 ISMS https://advisera.com/27001academy/blog/2016/02/01/key-performance-indicators-for-an-iso-27001-isms/

For example:
- Percent of business initiatives supported by the ISMS may be changed to Percent of business initiatives supported by the BCMS
- Percent of information security initiatives containing cost/benefit estimates may be changed to Percent of business continuity initiatives containing cost/benefit estimates
- Percent of agreements with information security clauses may be changed to Percent of agreements with business continuity clauses
- Numb er of security-related service downtimes may be changed to Number of service disruptions
- Duration of service interruptions can be maintained
- Incident resolution time may be changed to Achieved recovery time
- Percent of controls assessment performed may be changed to Percent of BCP tests performed
- Number of improvement initiatives can be maintained
