For a customer, the most useful number is usually:
Lead Time
Because lead time measures the customer’s waiting time.
Simple comparison
| Metric | Who cares most? | Why |
|---|---|---|
| Lead Time | Customer | “How long from my request until I get the result?” |
| Cycle Time | Team / manager | “How long did the team actively work on it?” |
| Throughput | Team / manager / planning | “How many items can we finish per week/sprint?” |
Example
A customer requests a new feature on Monday.
The team starts working on it on Thursday.
The feature is delivered on Friday.
| Metric | Value |
|---|---|
| Lead Time | Monday to Friday = 5 days |
| Cycle Time | Thursday to Friday = 2 days |
| Throughput | Example: team completed 12 items this week |
From the customer’s view, the answer is:
“I waited 5 days.”
So lead time is most customer-focused.
Teaching line
Customers usually care about lead time because it tells them how long they wait for value. Teams care about cycle time and throughput because those help improve the system that produces that value.
A good short answer:
Lead time is most useful for customers. Cycle time and throughput are more useful for the team to manage and improve delivery.
