CAS Operations and Process Management 3 — Questions and Answers
Question 1: In operations management, 'bottleneck analysis' is used to:
- Identify regulatory compliance risks in underwriting
- Find the step in a process that limits overall throughput (Correct answer)
- Analyze catastrophe loss accumulations
- Determine optimal reinsurance attachment points
Correct answer: Find the step in a process that limits overall throughput
Bottleneck analysis identifies the constraint or limiting step in a process that determines the maximum output rate of the entire system.
Question 2: Which of the following best describes 'poka-yoke' in process design?
- A Japanese term for continuous improvement
- An error-proofing mechanism that prevents mistakes or makes them immediately obvious (Correct answer)
- A visual management system using color-coded charts
- A scheduling technique for resource allocation
Correct answer: An error-proofing mechanism that prevents mistakes or makes them immediately obvious
Poka-yoke refers to mistake-proofing mechanisms designed into a process to prevent errors from occurring or to immediately detect them when they do.
Question 3: A P&C insurance company implements a statistical process control (SPC) chart to monitor loss ratios. What does a point outside the control limits indicate?
- Normal random variation in the loss ratio
- A process that may be experiencing special cause variation requiring investigation (Correct answer)
- The combined ratio has exceeded 100%
- The need to file a rate increase immediately
Correct answer: A process that may be experiencing special cause variation requiring investigation
A point outside control limits signals special cause variation — a non-random signal suggesting the process may have changed and warrants investigation.
Question 4: In the Theory of Constraints (TOC), once a bottleneck is identified, the next step is to:
- Immediately add resources to every process step
- Exploit the bottleneck by maximizing its utilization before adding resources (Correct answer)
- Eliminate the bottleneck step from the process entirely
- Outsource the bottleneck activity to a third party
Correct answer: Exploit the bottleneck by maximizing its utilization before adding resources
TOC prescribes exploiting the constraint first — getting maximum output from the existing bottleneck resource — before deciding to elevate or add capacity.
Question 5: What is 'demand variability' and why is it significant for insurance operations staffing?
- Variability in policyholder demands for coverage types, relevant to product design
- Fluctuations in workload volume over time that make capacity planning challenging (Correct answer)
- The range of deductible options offered in a policy
- Variation in claims severity across geographic regions
Correct answer: Fluctuations in workload volume over time that make capacity planning challenging
Demand variability refers to fluctuations in workload volume (e.g., catastrophe-driven claim surges), which complicates staffing decisions and resource planning.
Question 6: Which document serves as the primary governance tool defining roles, responsibilities, and accountabilities in a process management framework?
- RACI matrix (Correct answer)
- Process capability index
- Control chart
- Value stream map
Correct answer: RACI matrix
A RACI matrix (Responsible, Accountable, Consulted, Informed) clearly defines who does what in a process, preventing role confusion and accountability gaps.
Question 7: In actuarial ratemaking operations, what is the purpose of a 'rate change monitoring' process?
- To ensure premium rates are filed before regulatory deadlines
- To track and quantify the earned impact of implemented rate changes on the book of business (Correct answer)
- To compare rates against competitor pricing in the market
- To calculate actuarially indicated rate changes for the next filing
Correct answer: To track and quantify the earned impact of implemented rate changes on the book of business
Rate change monitoring tracks how implemented rate changes are earning into the in-force book, allowing actuaries to assess the financial impact on earned premiums.
