Certified Agile Service Manager Integrating ITSM, Lean, and DevOps 5 — Questions and Answers
Question 1: An agile service manager applies the Theory of Constraints (ToC) to an ITSM workflow. What is the FIRST step in the ToC process?
- Elevate the constraint by adding more resources
- Exploit the existing constraint to maximize its throughput
- Identify the system's single biggest constraint (Correct answer)
- Subordinate all other decisions to the constraint
Correct answer: Identify the system's single biggest constraint
The first step in ToC's five focusing steps is to identify the system's constraint — the bottleneck limiting overall throughput — before taking any action.
Question 2: A DevOps team uses 'immutable infrastructure' — replacing servers rather than patching them. How does this practice align with ITSM change management?
- It eliminates the need for change records entirely
- It makes changes consistent, auditable, and fully reversible through replacement (Correct answer)
- It bypasses change approval processes to increase speed
- It transfers change risk to the cloud provider
Correct answer: It makes changes consistent, auditable, and fully reversible through replacement
Immutable infrastructure replaces rather than modifies, ensuring all changes are deliberate, traceable, and can be reversed by redeploying a prior version.
Question 3: Which of the following ITSM metrics most directly maps to Lean's focus on reducing 'lead time'?
- First call resolution rate
- Change implementation time from request to deployment (Correct answer)
- Number of incidents per month
- SLA breach percentage
Correct answer: Change implementation time from request to deployment
Change implementation time (request to deployment) directly measures lead time — the total elapsed time from customer need to value delivery.
Question 4: In integrating ITSM and DevOps, 'toil' — as defined by Google SRE — refers to:
- Complex architectural decisions that require expert judgment
- Manual, repetitive, automatable operational work that scales with service growth (Correct answer)
- User-reported incidents that require immediate escalation
- Technical debt accumulated from rapid feature releases
Correct answer: Manual, repetitive, automatable operational work that scales with service growth
Toil is SRE's term for manual, repetitive, tactical work that grows linearly with service load and provides no enduring value — a direct Lean waste analog.
Question 5: A service team adopts 'dark launching' — deploying new service features to production without exposing them to users. This technique primarily benefits which integrated practice?
- Capacity management and performance testing under real load conditions (Correct answer)
- User acceptance testing in a staging environment
- Service catalog updates and approval workflows
- Supplier onboarding and contract management
Correct answer: Capacity management and performance testing under real load conditions
Dark launching tests new code under real production load without user exposure, providing accurate capacity and performance data not achievable in staging.
Question 6: Which statement best describes the relationship between Agile service management and ITIL 4's 'service value system'?
- Agile replaces the service value system with sprint ceremonies
- Agile practices provide the delivery mechanism that operates within the service value system's guiding principles and value chain (Correct answer)
- ITIL 4's service value system is incompatible with Agile sprint cadences
- Agile service management only applies to the 'obtain/build' activity in the value chain
Correct answer: Agile practices provide the delivery mechanism that operates within the service value system's guiding principles and value chain
Agile practices are delivery mechanisms that operate within ITIL 4's SVS, using its guiding principles and value chain activities to co-create value iteratively.
Question 7: An organization integrating ITSM, Lean, and DevOps wants to prevent re-occurrence of a major incident. Which integrated practice combination is most effective?
- Automated monitoring alerts combined with blameless post-mortems and problem record creation (Correct answer)
- Increasing change freeze windows and requiring more CAB approvals
- Assigning permanent ownership of incidents to the team that caused them
- Creating detailed runbooks and requiring sign-off before any future deployment
Correct answer: Automated monitoring alerts combined with blameless post-mortems and problem record creation
Combining observability, blameless post-mortems (DevOps/Lean), and problem records (ITSM) addresses recurrence prevention through detection, learning, and systemic fixes.
