Question #10
At the 10th sprint review, the stakeholders are disappointed and angry. They have determined that the product or system being built both will not meet their needs and will cost more than they are willing to spend.
What factors may have led to this? (choose three)
- A . Changes to the project plan were not adequately documented and shared
- B . The product owner has not been keeping the stakeholders aware of the progress of the project
- C . The project management office has not been engaged adequately
- D . The scrum master has not ensured that the project is transparent
- E . The stakeholders were not allowed to enter the development area
- F . The stakeholders haven’t been using sprint reviews to inspect and evaluate progress
Correct Answer: B,D,F
B,D,F
Explanation:
there is no project plan, the presence of stakeholders in the development area is probably not helping and there is no project management. Transparancy would avoid the surprise for the stakeholders. If the PO didn’t frequently update them, this can also lead to surprise and disappointent. If the stakeholders couldn’t attend the sprint review they would also not be up to date and missing out on an opportunity to inspect and adapt.

- D . Write the code to satisfy the test
Correct Answer: D
D
Explanation:
In TDD you start with writing the test before the code. This test cannot pass. If it does, the test is wrong. When the tests are written, the production code to satisfy the test will be written. Once all the tests succeeds, the product code is done.
