Measure Repetitive Task Time with Clear Start and Stop Rules
Create consistent time records for recurring work steps and keep delays separate from hands-on process time.
What is the problem?
Two workers can measure the same operation differently if one starts at material pickup and another at machine start. Define the observed unit and exact start and stop events before comparing records.
Step-by-step solution
Write down start and stop conditions for each process
State whether a cycle begins with material loading and ends at completion or final inspection. Decide how movement, waiting and equipment downtime should be labeled.
Record interruptions with a reason, not only a duration
Note material shortages, machine stops and handoff delays as they occur. A long recorded cycle alone does not explain whether the cause was the task or an external interruption.
Check the log and export an auditable copy
Find missing start or stop marks, separate interruption labels and retain the conditions alongside the CSV. Avoid using isolated measurements as definitive judgments of individual productivity.
Alternative method
A paper stopwatch log or spreadsheet with task ID, start, finish and interruption notes can work just as well, especially where gloves make touchscreens awkward.
Known limitations
Measured cycle duration alone does not establish legal working hours or a valid industrial engineering standard time. Payroll and compliance need separate records and rules.
Frequently asked questions
No. Define whether your goal is hands-on processing time or full elapsed time first, and keep the interruption reason for later interpretation.
