A project manager wants to forecast the completion date for a large feature that is currently in progress. The team has historical data for similar features, but the current feature is larger than any previous one. The project manager needs a forecast that accounts for the feature's size and the team's historical velocity. Which approach should they use?

Use the team's average velocity from the last sprint and divide the remaining story points by that velocity

Use a Monte Carlo simulation based on historical cycle time per story point to forecast the remaining duration

Use the median cycle time of the three most recent features

Use the average cycle time of all completed features and multiply by the number of story points in the current feature

A DevOps team wants to measure the reliability of their release process. They have data on deployment frequency, deployment success rate, and the time it takes to roll back a failed deployment. They want to identify whether the release process is becoming more reliable over time. Which metric should they track as the primary indicator?

Lead time from commit to production.

Change failure rate, calculated as the percentage of deployments that cause a failure in production.

Average rollback time for failed deployments.
