A value stream has a high throughput, but the lead time is increasing. The team's WIP is also increasing. The team is considering whether to add more resources to the bottleneck step. What is the most important consideration before doing so?

Whether the bottleneck is the constraint that limits the entire value stream

Whether the team has enough testing capacity

Whether the team's velocity is stable

Whether the lead time increase is due to demand variability

A value stream has a low defect escape rate, but the change failure rate is high. What does this combination suggest?

The team is not testing enough before release

The team is deploying too frequently

The team's definition of done is too lenient

The team's testing is effective at catching defects, but changes are still causing failures in production

A team reports a cycle time of 5 days, but the lead time is 25 days. The team is unsure where the time is going. What does this gap most likely indicate?

Work is waiting in queues or buffers before or after the team's active work

The team is spending too much time on defects

The team is working on too many items at once

The team's definition of done is too strict

Part of the Improve Quality and Flow in a Value-Driven Organization domain, which makes up ~24% of our current practice bank. ISTQB does not publish an official question count, but from its 120-minute exam (~50–80 total, ~12–19 in this domain), expect 2–4 from this objective — we provide 26 practice questions to prepare you well beyond it.
