Implement Phase Appendices

These appendices provide practical templates, checklists, registers, and implementation tools to support the five stages of the Implement Phase:

Identify Critical Business Services

Set Impact Tolerance
Conduct Scenario Testing
Improve Lessons Learned

The templates should be adapted to reflect the organisation’s size, complexity, regulatory environment, risk profile, governance structure, and operational resilience maturity.
