Leaders ask whether Claude Code is worth the spend. What do you measure?
Why B is the answer
Delivery outcomes such as cycle time and change failure rate
Measure outcomes rather than activity. Prompt counts and generated lines can rise while delivery gets worse.
In detail
- Measure outcomes rather than activity.
- Prompt counts and generated lines can rise while delivery gets worse.
- Compare with a baseline from before the rollout.
Use case
An illustrative scenario, not a real incident.
Leaders ask whether Claude Code pays off. Cycle time and change failure rate show what shipped and how well, where prompt counts would only show activity.

Q{"What does the metric show?"}
Q -->|"Activity"| A0["Prompts or lines of code"]
Q -->|"Outcomes"| A1["Cycle time and change failure rate"]Key point: Measure outcomes, not activity.
Why the other options are wrong
- A. Lines of code generated, ranked across each of the teams
- Generated lines measure volume, not value.
- C. The share of developers who say they enjoy using the tool
- Enjoyment matters, but it does not show value for the spend.
- D. The number of prompts each developer sends per week
- Prompt counts measure activity.
