I'll help you assess each objective for CM.L2-3.4.5 (Access Restrictions for Change) and prioritize the assessment approaches and evidence types for each objective.

Assessment Objective [b]: Physical access restrictions associated with changes to the system are documented

Evidence Types Ranking:

1. **Documents**: Primary evidence - formal documentation of restrictions 2. **Artifacts**: Supporting - access control lists, logs, forms 3. **Screen Share**: Useful to view electronic documentation systems 4. **Physical Review**: Limited value for this objective

Assessment Approach Priority:

1. **Examine**: Most important

  - Review physical access approvals, change control records, configuration management plan
  - Check for documentation of server room access procedures, datacenter entry requirements
  

2. **Interview**: Supplementary

  - Speak with physical security personnel and system administrators
  - Verify their understanding of documentation requirements
  

3. **Test**: Limited applicability

  - More relevant for enforcement than documentation

Each assessment objective requires a tailored approach with different emphasis on assessment methods and evidence types. The key is to ensure comprehensive coverage while focusing on the most relevant and efficient approaches for each specific objective.
