Question 1

A pilot for business cases, sourcing and model economics reaches a decision point for the procurement steering group. The current solution leaves outcome metrics tied to an existing process baseline unresolved, and the gap is now affecting the stated business or technical requirement. What is the best design choice?

1. Choose outcome metrics tied to an existing process baseline.
2. Perform sensitivity analysis for low adoption.
3. Treat adoption assumptions separately from realized benefits and evaluate each with its own evidence.
4. Include exit and data portability in a buy decision in the architecture or business-case boundary before comparing alternatives.
5. Buy when the mandatory process is supported with low differentiation.

Correct Answer: A

 

Correct Answer

Question 10

An AI initiative is expected to produce $420,000 of measurable benefit in each of two years. Integration costs $140,000 once, and operations cost $170,000 per year. Using a two-year horizon and ignoring discounting, what is the net benefit?

1. $420,000
2. $700,000
3. $360,000
4. $500,000
5. $560,000

Correct Answer: C

 

Correct Answer

Answer C is correct because 840,000 – 140,000 – 340,000 = 360,000. This comparison uses the exact quantities and calculation boundary stated in the scenario rather than a different cost or benefit definition.

Incorrect Answers

Answer A is incorrect because This subtracts only one recurring year of operations and therefore overstates the result. This comparison uses the exact quantities and calculation boundary stated in the scenario rather than a different cost or benefit definition.

Answer B is incorrect because This is close to the gross two-year benefit and fails to subtract the full one-time and recurring cost boundary stated in the scenario, so it overstates net benefit.

Answer D is incorrect because This subtracts the one-time integration cost but ignores both years of operating cost. This comparison uses the exact quantities and calculation boundary stated in the scenario rather than a different cost or benefit definition.

Answer E is incorrect because This subtracts only the operating cost and ignores integration cost. This comparison uses the exact quantities and calculation boundary stated in the scenario rather than a different cost or benefit definition.

 

Question 11

A proposed agent has $750,000 of expected benefit and $500,000 of total implementation and operating cost over the analysis horizon. The organization defines ROI as (benefit – cost) / cost. What ROI should the architect report?

1. 33%
2. 50%
3. 67%
4. 150%
5. 25%

Correct Answer: B

 

Correct Answer

Answer B is correct because (750 – 500) / 500 = 0.50, or 50%. This comparison uses the exact quantities and calculation boundary stated in the scenario rather than a different cost or benefit definition.

Incorrect Answers

Answer A is incorrect because This does not match either the stated numerator or denominator. This comparison uses the exact quantities and calculation boundary stated in the scenario rather than a different cost or benefit definition.

Answer C is incorrect because This would use a different denominator than the one explicitly defined. This comparison uses the exact quantities and calculation boundary stated in the scenario rather than a different cost or benefit definition.

Answer D is incorrect because This is benefit divided by cost, not net benefit divided by cost. This comparison uses the exact quantities and calculation boundary stated in the scenario rather than a different cost or benefit definition.

Answer E is incorrect because 250/750 would use benefit as the denominator, not the stated formula. This comparison uses the exact quantities and calculation boundary stated in the scenario rather than a different cost or benefit definition.

 

Question 12

An AI solution requires a $240,000 initial investment and is expected to generate a uniform $40,000 net benefit per month after launch. Ignoring discounting, what is the simple payback period?

1. 10 months
2. 4 months
3. 5 months
4. 8 months
5. 6 months

Correct Answer: E

 

Correct Answer

Answer E is correct because 240,000 divided by 40,000 per month equals 6 months. This comparison uses the exact quantities and calculation boundary stated in the scenario rather than a different cost or benefit definition.

Incorrect Answers

Answer A is incorrect because This assumes a much lower monthly benefit than the one stated. This comparison uses the exact quantities and calculation boundary stated in the scenario rather than a different cost or benefit definition.

Answer B is incorrect because 240/40 is not 4. This comparison uses the exact quantities and calculation boundary stated in the scenario rather than a different cost or benefit definition.

Answer C is incorrect because 240/40 is not 5. This comparison uses the exact quantities and calculation boundary stated in the scenario rather than a different cost or benefit definition.

Answer D is incorrect because This assumes a lower monthly benefit than the one stated. This comparison uses the exact quantities and calculation boundary stated in the scenario rather than a different cost or benefit definition.

 

Question 13

During a design workshop on business cases, sourcing and model economics, the portfolio review board identifies a constraint. Existing evidence is insufficient to make a safe release or architecture decision about a staged rollout with delayed benefits. What is the best design choice?

1. Evaluate a staged rollout with delayed benefits.
2. Buy when the mandatory process is supported with low differentiation.
3. Choose outcome metrics tied to an existing process baseline.
4. Choose staged sourcing because requirements remain uncertain is the decisive constraint.
5. Test long-context requests against candidate model limits.

2. Calculate payback under a uniform monthly benefit assumption from the stated values and use the result rather than an activity proxy.
3. Compare routing cost against a fixed-model baseline.
4. Distinguish capacity released from headcount reduction and do not treat the two conditions as equivalent.
5. Include governance and evaluation effort in the business case in the architecture or business-case boundary before comparing alternatives.

Correct Answer: C

 

Correct Answer

Answer C is correct because This is correct because it applies the reserved architecture decision—compare routing cost against a fixed-model baseline—to the decisive constraint in the scenario. It keeps the action at the appropriate business cases, sourcing and model economics boundary and produces a result that can be verified before wider deployment.

Incorrect Answers

Answer A is incorrect because This is not the best choice because it addresses the adjacent decision ‘extend when existing capabilities cover the stable core’ rather than the scenario’s decisive requirement. Although that action can be valid within business cases, sourcing and model economics, selecting it here would leave the stated constraint unresolved or move the design to the wrong stage.

Answer B is incorrect because This is not the best choice because it addresses the adjacent decision ‘calculate payback under a uniform monthly benefit assumption’ rather than the scenario’s decisive requirement. Although that action can be valid within business cases, sourcing and model economics, selecting it here would leave the stated constraint unresolved or move the design to the wrong stage.

Answer D is incorrect because This is not the best choice because it addresses the adjacent decision ‘distinguish capacity released from headcount reduction’ rather than the scenario’s decisive requirement. Although that action can be valid within business cases, sourcing and model economics, selecting it here would leave the stated constraint unresolved or move the design to the wrong stage.

Answer E is incorrect because This is not the best choice because it addresses the adjacent decision ‘include governance and evaluation effort in the business case’ rather than the scenario’s decisive requirement. Although that action can be valid within business cases, sourcing and model economics, selecting it here would leave the stated constraint unresolved or move the design to the wrong stage.

 

Question 35

A routing strategy reduces aggregate model spend, but the cheaper route fails the organization’s acceptance threshold on a small set of critical decisions. Which conclusion should the investment committee draw?

1. Compare supplier dependence against time-to-value.
2. Evaluate a staged rollout with delayed benefits.
3. Define an analysis horizon consistent with asset life.
4. Interpret a negative outcome when quality rework offsets speed.
5. Reject aggregate savings that conceal failure on critical tasks.

Correct Answer: E

 

Correct Answer

Answer E is correct because This is correct because it applies the reserved architecture decision—reject aggregate savings that conceal failure on critical tasks—to the decisive constraint in the scenario. It keeps the action at the appropriate business cases, sourcing and model economics boundary and produces a result that can be verified before wider deployment.
