First of all AnandR, there is no requirement for an MRM or management review meeting. The requirement is for management to review the required inputs and come up with sensible outputs. You can do this is in various ways other than a meeting. I've seen organizations with management abroad doing management reviews via email exchanges.
I will answer the ISMS part first. You asked:
1) Results of ISMS audits and reviews
2) Feedback from interested parties on ISMS
3) Techniques, products or procedures, which could be used in the organization to improve the ISMS performance and effectiveness
4) Results from effectiveness measurements
1. Reviews are activities distinct from audits which can help ensure the preservation of CIA of your information assets. Reviews encompass technical vulnerability reviews such as penetration testing and vulnerability assessments.
2. Interested parties to your ISMS may include customers, stakeholders, the government, employees, contractors, 3rd-party vendors, consultants, etc.
3. Supposed one of your higher risk is employees tail-gating the main door and bypassing the current swipe card access. A product which can improve this situation such as installing a turnstile system could be part of the management review. The same goes for new products or techniques in the market which could lower your risk exposure and improve performance. A new co-lo site perhaps? A faster internet service provider?
4. There is a requirement to measure the effectiveness of the chosen and implemented controls. Make sure the results of the measurement process are part of the management review.
Will get back later after dinner. Wifey calling me.
