Question 1

A software product is being developed with a projected market size of 100,000 potential users. The development cost is estimated at €500,000, and the desired profit margin is 30%. What should be the minimum selling price per unit to achieve the desired profit?

Accepted Answer

€7.15

Answer

€5.00

Answer

€6.50

Answer

€8.00

Question 2

A product manager is deciding between two feature sets for a new mobile app. Feature set A is estimated to increase user engagement by 20% but will take 3 months to develop. Feature set B is estimated to increase user engagement by 10% and will take 1 month to develop. If user engagement is currently at 1000 active users per day, which feature set provides the greater increase in total user-days over a 6-month period (approximately 180 days)? Show your calculations.

Accepted Answer

Feature set B provides a greater increase in total user-days. Feature set A: 1000 * 1.20 * (180 - 90) = 108,000 user-days. Feature set B: 1000 * 1.10 * (180 - 30) = 165,000 user-days.

Question 3

Accepted Answer

True

Answer

False

Question 4

A product manager is evaluating two marketing strategies. Strategy A is projected to increase sales by 15% with a cost of €10,000. Strategy B is projected to increase sales by 10% with a cost of €5,000. If current sales are €100,000, which strategy provides a higher return on investment (ROI)?

Accepted Answer

Strategy B

Answer

Strategy A

Answer

Both have the same ROI

Answer

Cannot be determined

Question 5

Which of the following are key considerations when defining a product vision?

Answer

Technical architecture

Answer

Target customer

Answer

Customer needs

Answer

Market trends

Answer

Development team size

Question 6

A product manager is tasked with increasing user retention for a subscription-based service. The current churn rate is 5% per month. The goal is to reduce it to 2% within 6 months. If there are currently 1000 subscribers, how many new subscribers per month are needed to maintain a steady subscriber base while achieving the target churn rate?

Accepted Answer

Approximately 31 new subscribers per month.  Subscribers lost per month at 5%: 1000 * 0.05 = 50. Subscribers lost per month at 2%: 1000 * 0.02 = 20.  Therefore, 20 new subscribers are needed to offset churn. To reduce churn to 2% in 6 months, the average churn rate is (5-2)/6 = 0.5% reduction per month. This means the number of subscribers lost decreases each month. The average number of subscribers lost over the 6 months is approximately 31. Therefore, approximately 31 new subscribers are needed each month.

Question 7

C. To create the final product

Answer

D. To document the product architecture

Question 12

Explain the difference between a feasibility demonstration prototype and a customer demonstration prototype.

Accepted Answer

A feasibility demonstration prototype is used to test the technical viability of an idea, while a customer demonstration prototype is used to gather feedback on features and usability from potential users.

Question 13

A development team estimates that a new feature will take 8 story points to implement. If the team's velocity is 4 story points per sprint, how many sprints will it take to complete the feature?

Accepted Answer

B. 2

Answer

A. 1

Answer

C. 3

Answer

D. 4

Question 14

A product manager is evaluating a new user interface design. The average task completion time for a key user flow is currently 5 minutes with a standard deviation of 1 minute. After implementing the new design, the average completion time drops to 4 minutes with a standard deviation of 0.8 minutes. Assuming a normal distribution, what is the approximate percentage decrease in the average task completion time?

Accepted Answer

B. 20%

Answer

A. 10%

Answer

C. 25%

Answer

D. 30%

Question 15

In acceptance testing, a critical module is expected to process 1000 transactions per second. During testing, it processes 850 transactions per second. Calculate the percentage shortfall in performance and explain its significance.

Accepted Answer

15%. This indicates a performance bottleneck that needs to be addressed before release.

Question 16

Customer testing is primarily focused on identifying functional bugs rather than assessing usability and overall satisfaction.

Accepted Answer

True

Answer

False

Question 17

A product manager is analyzing customer feedback from a beta test. 80% of users rated the product's ease of use as 'good' or 'excellent'. If 200 users participated in the beta test, how many users did NOT rate the product's ease of use as 'good' or 'excellent'?

Answer

C. Ensuring the product is efficient and reliable.

Answer

D. Developing tests that reflect how customers use the product.

Answer

E. Designing the user interface.

Question 19

A user interface design change is expected to reduce the average time spent on a critical task from 10 minutes to 8 minutes. If 5000 users perform this task daily, calculate the total time saved per day in minutes.

Accepted Answer

10,000 minutes. (2 minutes/user * 5000 users = 10,000 minutes)
