41. Launching with a known bug
Launch is tomorrow. QA finds a bug affecting about 2% of users in an edge case, with an easy workaround and no data loss or security risk. Marketing is ready. What do you do?
- A.Assess the risk, launch behind a feature flag with monitoring, share the known issue and workaround with support, and schedule the fix
- B.Delay the launch by a month until the product is perfect
- C.Launch and tell nobody about the bug
- D.Cancel the launch completely
Show answer
Answer: A. Assess the risk, launch behind a feature flag with monitoring, share the known issue and workaround with support, and schedule the fix
Not every bug is a launch blocker. When severity is low and a workaround exists, launching with monitoring, support briefing and a planned fix balances quality and business needs. Data loss, security or payment bugs would be a different decision.
42. The near-critical path
Your critical path is 60 days. A second path is 58 days long and full of uncertain tasks. What is the best way to manage it?
- A.Ignore it, because only the critical path can delay the project
- B.Manage the near-critical path closely too, because a small slip makes it critical, and use schedule risk analysis to see the real chance of finishing on time
- C.Crash only the critical path so it is far shorter than the second path
- D.Move all buffer to the critical path and remove it from other paths
Show answer
Answer: B. Manage the near-critical path closely too, because a small slip makes it critical, and use schedule risk analysis to see the real chance of finishing on time
With only 2 days of float and high uncertainty, the second path may well become the one that decides the end date. Focusing only on today's critical path gives false comfort. Monte Carlo or similar analysis shows how often each path ends up driving the finish.
43. Build or buy decision tree
Buying a tool costs a certain $120,000. Building it costs $80,000 with a 70% chance, but a 30% chance of overruns bringing the total to $180,000. Based on expected monetary value, what should you choose?
- A.Buy, because $120,000 is lower than the $130,000 expected for building
- B.Build, with an expected cost of $110,000
- C.Build, with an expected cost of $80,000
- D.Buy, with an expected cost of $110,000
Show answer
Answer: B. Build, with an expected cost of $110,000
Expected cost of building = 0.7 x 80,000 + 0.3 x 180,000 = 56,000 + 54,000 = 110,000, which is lower than 120,000 for buying. EMV favours building. In practice, a risk-averse organisation might still buy to avoid the 30% chance of a $180,000 outcome, so state that trade-off.
44. Secondary risk
To avoid a vendor delay you bring the work in-house, but this creates a new risk that your team lacks experience. What is this new risk called?
- A.A residual risk
- B.A risk trigger
- C.A secondary risk
- D.An emergent risk
Show answer
Answer: C. A secondary risk
A secondary risk is caused directly by carrying out a risk response. A residual risk is what remains of the original risk after the response. Both should be recorded in the risk register with their own owners.
45. Several critical paths at once
After compression, a schedule has four parallel critical paths of equal length. How does this affect the chance of finishing on time?
- A.It rises, because work is shared across more paths
- B.It is unchanged, because the end date is the same
- C.It falls, because a delay on any one path delays the end
- D.It rises, because float is spread more evenly
Show answer
Answer: C. It falls, because a delay on any one path delays the end
With one critical path, only that chain has to go well. With four, all four must finish on time, so the joint probability of hitting the date is lower. Compression that creates many critical paths adds risk even when the date looks the same.
46. Probability within one sigma
A path has a PERT mean of 40 days and a standard deviation of 4 days. Assuming a normal distribution, roughly what is the chance of finishing within 44 days?
- A.About 68%
- B.About 50%
- C.About 95%
- D.About 84%
Show answer
Answer: D. About 84%
44 days is one standard deviation above the mean. About 50% of outcomes are below the mean and about 34% lie between the mean and +1σ, so roughly 84% finish within 44 days. The 68% figure is for the range mean ± 1σ.
47. Standard deviation of a path
Two activities in series have PERT standard deviations of 3 days and 4 days. Treating them as independent, what is the standard deviation of the path?
- A.7 days
- B.5 days
- C.12 days
- D.3.5 days
Show answer
Answer: B. 5 days
Variances add, not standard deviations. Path variance = 3² + 4² = 9 + 16 = 25, so path σ = √25 = 5 days. Adding the σ values directly (7 days) overstates the spread.
48. Sizing contingency from a simulation
The base cost estimate is ₹5.0 crore. A Monte Carlo cost model gives P50 = ₹5.4 crore and P80 = ₹5.9 crore. The sponsor wants 80% confidence. How much contingency should be added to the base?
- A.₹0.4 crore
- B.₹0.5 crore
- C.₹5.9 crore
- D.₹0.9 crore
Show answer
Answer: D. ₹0.9 crore
To fund the project at P80, the budget should be ₹5.9 crore. Contingency = P80 − base = ₹5.9 crore − ₹5.0 crore = ₹0.9 crore. The P50 − base gap (₹0.4 crore) would give only about even odds.
49. Is the mitigation worth it
A threat has a 40% chance of a ₹50 lakh loss. A mitigation costs ₹6 lakh and cuts the chance to 10%. What is the net benefit of mitigating?
- A.₹15 lakh
- B.₹14 lakh
- C.₹20 lakh
- D.₹9 lakh
Show answer
Answer: D. ₹9 lakh
EMV before = 0.4 × 50 = ₹20 lakh; after = 0.1 × 50 = ₹5 lakh. Risk reduction is ₹15 lakh, minus the ₹6 lakh cost gives a net benefit of ₹9 lakh, so the mitigation pays off.
50. The Three Lines Model
In the IIA Three Lines Model, who provides the "third line" role?
- A.Front-line managers who own risks
- B.Risk and compliance teams who advise
- C.External regulators who set rules
- D.Internal audit, giving independent assurance
Show answer
Answer: D. Internal audit, giving independent assurance
First-line roles own and manage risk in daily operations; second-line roles such as risk and compliance give expertise and challenge; internal audit is the third line, giving independent assurance to the governing body.
51. Preparing for black swans
Leadership asks how to manage rare, extreme events nobody can predict, like a pandemic. What is the most useful approach?
- A.Predict them with better probability models
- B.Build resilience, such as buffers and flexible plans
- C.Ignore them, since they cannot be foreseen
- D.Insure against every possible event
Show answer
Answer: B. Build resilience, such as buffers and flexible plans
Black swans are by nature hard to forecast. Rather than predicting them, organisations build resilience: spare capacity, diversified suppliers, tested continuity plans and the ability to adapt fast.
52. A culture that hides risk
Team members who report risks in a company are often blamed for "being negative", and fewer risks are now raised. What is the biggest danger?
- A.Risks stay hidden until they become costly issues
- B.The risk register becomes shorter and easier to manage
- C.Projects will be more optimistic and therefore faster
- D.People will raise only the highest-impact risks
Show answer
Answer: A. Risks stay hidden until they become costly issues
When raising risks is punished, people stay silent, so the organisation loses early warning. Leaders should thank those who raise risks and treat transparency as a strength.
53. A risk burndown chart
A programme plots total risk exposure (sum of EMVs) each month. It falls from ₹2 crore to ₹1.2 crore, then rises to ₹1.6 crore. What does the rise most likely mean?
- A.Responses worked better than planned
- B.The chart was set up incorrectly
- C.New risks were found or existing ones grew
- D.The project has fewer risks than before
Show answer
Answer: C. New risks were found or existing ones grew
A risk burndown tracks how exposure falls as risks are retired. A rise shows new or growing risks, which leaders should look into, for example a new dependency or a supplier problem.
54. Fourth-party risk
Your payroll vendor hosts its system on a cloud provider you have no contract with. What is this exposure called?
- A.Second-party risk
- B.Inherent risk
- C.Fourth-party risk
- D.Secondary risk
Show answer
Answer: C. Fourth-party risk
Fourth parties are your vendors' vendors. You depend on them but have no direct control, so due diligence should ask how the vendor manages its own suppliers.
55. Many small risks together
A programme has 60 small risks, each rated "low", all tied to one overloaded vendor. What does looking at them only one by one miss?
- A.Their combined effect from a common cause may be high
- B.Low risks never need a response
- C.Each should be closed to clean up the register
- D.They should be transferred to the vendor
Show answer
Answer: A. Their combined effect from a common cause may be high
Risks that share a cause can happen together and add up. Grouping risks by root cause or source reveals concentrations that single ratings hide, and a single response can address many of them.
56. A risk owned at the wrong level
The risk "the regulator may change licensing rules" is assigned to a junior analyst as owner. What is the main problem?
- A.Junior staff cannot read regulations
- B.They lack the authority to manage the risk
- C.Regulatory risks need no owner
- D.The analyst will close it too early
Show answer
Answer: B. They lack the authority to manage the risk
A risk owner must have enough authority and resources to make sure responses happen, here likely a compliance head. An analyst may help with monitoring as an action owner.
57. CPI as a risk signal
At 25% complete, a project's cost performance index (CPI) is 0.85. What does research on earned value suggest?
- A.CPI will return to 1.0 on its own
- B.CPI rarely improves much, so expect an overrun
- C.CPI below 1 means the project is ahead
- D.CPI is meaningless before 50% complete
Show answer
Answer: B. CPI rarely improves much, so expect an overrun
Studies of many projects found CPI tends to stabilise early and rarely improves much after about 20% complete. A CPI of 0.85 is an early warning that the budget will likely be exceeded unless something changes.
58. Paying more than expected loss
A fire would cost a small factory ₹2 crore with a 0.5% yearly chance (EMV ₹1 lakh). Insurance costs ₹1.5 lakh a year. Why might buying it still be wise?
- A.Insurance always costs less than EMV
- B.A ₹2 crore loss could ruin the firm
- C.EMV is wrong for fire risks
- D.The premium reduces fire probability
Show answer
Answer: B. A ₹2 crore loss could ruin the firm
Expected value ignores the firm's ability to survive a loss. Paying a premium above EMV is rational when the loss would be ruinous, which is why risk-averse businesses insure.
59. Too much risk control
A team adds approvals, reviews and sign-offs for every small change to avoid any risk. Release time grows from 2 days to 3 weeks. What is the main lesson?
- A.More controls always lower overall risk
- B.Speed does not matter if risk is low
- C.Controls have costs; match them to the risk level
- D.Approvals should be removed entirely
Show answer
Answer: C. Controls have costs; match them to the risk level
Excess control can create new risks, such as slow fixes and lost market chances. Proportionate controls, stronger for high-risk changes and lighter for small ones, balance safety and speed.
60. Residual risk above appetite
After all planned responses, a risk's residual level is still above the organisation's appetite. What should happen?
- A.Record it as closed since the responses are now done
- B.Lower the appetite so that the risk fits within it
- C.Escalate for a decision: act more, accept formally, or change
- D.Hide it in the register until the next audit comes
Show answer
Answer: C. Escalate for a decision: act more, accept formally, or change
If residual risk exceeds appetite, someone with the right authority must decide whether to invest in more responses, change the plan, or formally accept the exposure. It should not be left silently.
