Question 20
A service team claims improved throughput from ticket counts while deployments and recovery times are worsening. Which unsupported assumption should the engineer challenge FIRST?
Explanation
Correct Answer
An increased ticket closure count is not necessarily increased delivery of stable working software. This is the relevant unsupported assumption because flow measurement should distinguish finished customer value from work merely moved between administrative states.
Incorrect Answers
This is the relevant unsupported assumption because planning estimates are not a universal productivity measure across teams with different scope and scales. The relevant evidence instead is: An increased ticket closure count is not necessarily increased delivery of stable working software.
This is the relevant unsupported assumption because dashboards require validated query grain and data lineage to prevent misleading delivery counts. The acceptance criterion here is: An increased ticket closure count is not necessarily increased delivery of stable working software.
This is the relevant unsupported assumption because a time-to-restore metric must follow the customer-visible outage, not administrative ticket lifecycle changes. What must be demonstrated is: An increased ticket closure count is not necessarily increased delivery of stable working software.
