CTE Customer Experience & Operational Excellence 2 — Questions and Answers
Question 1: A telecom operator sees a spike in customer churn 30 days after service installation. Which metric best identifies the root cause?
- Average Revenue Per User (ARPU)
- First Call Resolution (FCR) rate
- Time-to-install variance
- Net Promoter Score at day-30 touchpoint (Correct answer)
Correct answer: Net Promoter Score at day-30 touchpoint
A day-30 NPS survey captures the customer's first full billing cycle experience and pinpoints satisfaction drivers linked to early churn.
Question 2: Which operational framework is most commonly used by telecom operators to standardize IT service management processes and reduce incident response time?
- Six Sigma DMAIC
- ITIL (Information Technology Infrastructure Library) (Correct answer)
- Lean Manufacturing
- ISO 9001
Correct answer: ITIL (Information Technology Infrastructure Library)
ITIL provides a structured set of IT service management best practices widely adopted by telecoms to streamline incident, change, and problem management.
Question 3: A CTE candidate is reviewing a carrier's Mean Time To Repair (MTTR) KPI. What does a rising MTTR trend most likely indicate?
- Improved network redundancy
- Degraded technician efficiency or process bottlenecks (Correct answer)
- Increased customer satisfaction
- Lower network complexity
Correct answer: Degraded technician efficiency or process bottlenecks
Rising MTTR signals that repairs are taking longer, typically due to skill gaps, parts shortages, or inefficient escalation processes.
Question 4: In a telecom contact center, what does the 'occupancy rate' measure?
- Percentage of agents handling calls vs. total scheduled agent time (Correct answer)
- Number of calls resolved without escalation
- Customer wait time before agent pickup
- Ratio of inbound to outbound calls
Correct answer: Percentage of agents handling calls vs. total scheduled agent time
Occupancy rate tracks the proportion of time agents spend handling contacts versus their total available time, indicating workforce utilization.
Question 5: A telecom company wants to proactively reduce truck rolls. Which technology investment best achieves this?
- Expanding retail store footprint
- Deploying remote diagnostics and network monitoring tools (Correct answer)
- Increasing call center headcount
- Offering longer installation windows
Correct answer: Deploying remote diagnostics and network monitoring tools
Remote diagnostics allow technicians to identify and resolve network issues without a physical visit, directly reducing costly truck rolls.
Question 6: Which customer segmentation approach allows a telecom to prioritize operational resources toward highest-value accounts during a service outage?
- Geographic segmentation
- Demographic segmentation
- Lifetime Value (LTV) tiering (Correct answer)
- Psychographic segmentation
Correct answer: Lifetime Value (LTV) tiering
LTV tiering lets operators prioritize restoration efforts toward high-revenue customers, protecting churn risk where financial impact is greatest.
Question 7: What is the primary purpose of a telecom's 'Voice of the Customer' (VoC) program?
- Train call center agents on scripted responses
- Systematically collect and act on customer feedback to drive service improvements (Correct answer)
- Monitor employee performance metrics
- Audit network infrastructure compliance
Correct answer: Systematically collect and act on customer feedback to drive service improvements
VoC programs aggregate customer feedback from multiple channels to identify pain points and inform product, process, and service improvements.
