Question 40 sur 40
40. Question
1 pointsYou work for Personal Transport Devices Ltd., which makes bicycles, scooters, skateboards and any other self-powered or electrically assisted device that moves a person reliably and is easily stored. You have been asked to develop a rental scooter that can be picked up and dropped off at publicly accessible locations of the customer’s choosing for European urban markets.
Note: In order to frame this question with recognizable approaches, the Designing for Growth approach is assumed to have been adopted by Personal Transport Devices Ltd. in this scenario.
The learning launch named ‘Endspurt Eins’ was conducted in the Charlottenburg and Spandau boroughs of Berlin. The learning launch was moderately successful. There were a number of suggestions on how to adapt the rental scooter to Berlin’s cultural, regulatory and environmental climate. The customer co-creation activities were performed in Paris. Learning launch results from Berlin show European urban-universality is a poor assumption as it relates to this rental scooters.
The new products leadership has reviewed your report and took in your presentation on ‘Endspurt Eins.’ The leaders’ mood was favorable. They considered most of the issues related to services that can be easily customized. As you leave the meeting, you hear the leaders discussing a London rollout in time for next spring.
What design thinking considerations would you point out to the leaders for rollout planning?
Exact
A. INCORRECT: At least from the company’s perspective, this recommendation is based on an untested assumption. Bicycles and scooters are simply different. The differences are sufficient to question the validity of the analogy.
B. INCORRECT: Having a recognized brand will help with initial interest. However it will not address weak execution and poor value. Market advantage is only advantage if the differentiators are of value to the end user. Beating the competition in something no one wants is not much of a win.
C. INCORRECT: The effort showed that important assumptions were not reliable. This lesson is worth learning and avoiding going forward. What will the commercial design team build instead? Based on what understanding? What untested assumptions will the commercial design team make? Design is a constant skirmish between requirements and priorities. Giving up before the battle starts makes the design thinking effort rather pointless.
D. CORRECT: The recommendation is consistent with 3.3.1 paragraph 2. Personal Transport Devices management should seriously consider assumptions that were proven to be weak. They may be risks for the London effort. Those features, qualities and insights that are common and different should help product management spot where city specific design changes may be necessary.

Question 40 sur 40
40. Question
Which of the following combination represents relevant aspects and questions to ask during a test generation tool evaluation?
1.Test case relevance
2.Defect relevance
3.Test case explosion
4.Maintainability
a.Which counter measures are in place?
b.How high is the expected customer impact?
c.Is there monitoring of effort and added benefit?
d.Are business use cases and associated risks covered?
Exact
The correct answer is A. Test cases should cover business use cases and associated risks (section 3.5.6). Revealed defects should have a high expected customer impact (section 3.5.9). There should be counter measures to test case explosion in place (at least a metric how many test cases are sensible, see section 3.5.7). And test case maintenance should be monitored in terms of effort and benefit (section 3.5.8).
