Process cycle efficiency: how much of the wait is work?

Key takeaways

Process cycle efficiency (PCE) is touch time divided by lead time, shown as a percentage. It tells you how much of the customer's wait is spent actually working on their request. Office processes commonly score below 10%, because most of the time is waiting. Raising PCE means removing waits, not asking people to work faster.

• Formula: touch time divided by lead time, times 100.
• Office processes commonly score below 10%.
• A low score means waiting, not slow work.
• Raise it by removing queues, approvals and batches.

What is process cycle efficiency?

Process cycle efficiency is the share of total lead time spent on value-adding work. Lean practitioners also call it flow efficiency. If a request takes 40 minutes of work and the customer waits two working days of 7.5 hours, PCE is 40 minutes out of 900, or about 4%. The other 96% is the request waiting.

How do you calculate it?

Measure touch time and lead time for ten items in the same units, usually working minutes. Divide average touch time by average lead time and multiply by 100. Count only the work that moves the item forward. Rework, chasing and searching for information are not value-adding, even though someone is busy.

• 1. Choose one process with a clear start and end.
• 2. Time the active work on ten items.
• 3. Measure lead time for the same items.
• 4. Divide touch time by lead time.

What is a good score?

There is no fixed good score, but the trend matters. A process at 3% that moves to 15% has cut most of its waiting. Above about 25% in office work, the remaining gains usually come from making the work itself simpler. Compare your process with itself over time, not with other businesses.

What does improving it look like in numbers?

In an illustrative example, supplier invoice approval has 12 minutes of touch time and a lead time of six working days, a PCE of under 1%. Replacing a weekly approval meeting with a daily approval list and a named deputy cuts lead time to one day, raising PCE to about 3%. Example figures. The gain came from removing waiting, not from faster work.

• Approval bottlenecks: when sign-off holds up the work
• Purchase-to-pay process: faster, cleaner supplier payments

How do you raise process cycle efficiency?

Raise PCE by removing the waits between steps. Give the queue a daily owner, limit work in progress, release batches daily, delegate low-risk approvals and collect all the information needed at the start. Outsourcing helps when a dedicated team can work the queue continuously instead of fitting it around other jobs.

• Work queue management: stop jobs waiting in the back office
• Little's law: why more work in progress slows delivery
• Batching admin tasks: when it helps and when it slows you

When is a low score fine?

A low score is fine when waiting is built in and costs nothing, such as a cooling-off period or a scheduled review. It is also less important for internal work nobody waits for. Focus on processes where the customer or a senior person is waiting on the result.

What does this look like in practice?

A pattern we see: a team asked to speed up a process tries to work faster and gains a few minutes. Calculating PCE shows the work is a tiny share of the wait. Moving the queue to a team that works it daily delivers a far larger gain with no change to the work itself.
