A value stream's lead time has been decreasing, but the throughput has also decreased. The team is celebrating the faster delivery. What should the team do?

Investigate why throughput decreased, as it may indicate a loss of capacity or demand

Celebrate the lead time improvement and continue as is

Increase the WIP limit to boost throughput

Reduce the defect escape rate to improve throughput

A value stream has a stable lead time of 10 days, but the cycle time varies widely from 1 to 9 days. The team is considering reducing the cycle time variability. What is the most likely benefit of this improvement?

It will increase the throughput of the value stream

It will eliminate the need for a WIP limit

It will make the lead time more predictable, improving planning and customer trust

It will reduce the lead time to 5 days

A value stream's change failure rate has risen from 5% to 20% over two months, while lead time has decreased. The team is celebrating the faster delivery. What should the team leader do?

Celebrate the lead time improvement and monitor the change failure rate for another month

Investigate the root cause of the increased failure rate before further reducing lead time

Reduce the defect escape rate by adding more testing at the end of the process

Increase the team's velocity to offset the higher failure rate
