Quick answer
What is SMV in garments?
SMV (Standard Minute Value) is the time a trained operator needs to complete an operation at standard pace, including allowances.
Basic time = Observed time × Rating%
How it works
SMV Calculator
Turn a stopwatch time study into a standard minute value, then into target output per hour.
Observed time is normalised to a standard pace with the rating, then allowances are added for rest and unavoidable delays.
Formula
The formula, in full
- Basic time
- Observed time × Rating%
- SMV
- Basic time × (1 + Allowance%)
- Output / hr
- 60 ÷ SMV × Efficiency%
Example
Collar attach
- 01Observed = 0.70 min
- 02Basic = 0.63 min
- 03SMV = 0.7245 min
- 04Output = 58 pcs/hr at 70%

Industry tip
Industry tip
“Take at least 10 cycles per operation and discard abnormal readings before averaging.”
Assumptions
