Process time is the time that the product or service is actually being worked on by an operator or employee. Process times can be observed and gathered using a stopwatch.
Process time is often hard to grab in the "moment", using a camera can be a helpful way to ensure you have the complete and accurate process time.
How to Calculate:
Process time is calculated by adding the actual work time to the walking time to the waiting time. Machine time is not included.
George is machining a part. While george is machining John observes a work time of 4 minutes, a walking time of 2 minutes and a waiting time of 6 minutes. That means his process time is 12 minutes total.
Sam is assembling a tricycle for his daughter. He walks to and from the assembly for tools for a total of 13 minutes during the process. He then waits for his wife Susan to go and pick up some WD-40 for the bike. That takes Susan 23 minutes. When Sam finally completes the assembly he worked a total of 42 minutes. What was Sam's processing time?
