This document discusses the calculation and importance of standard minute value (SMV) in the apparel industry. It defines SMV as the basic time plus allocated allowances needed to produce a garment. Basic time is calculated as the observed time multiplied by a rating factor and represents the likely minimum time required. Observed time is the recorded time taken under close observation. Rating factors adjust for worker speed. SMV is important for costing, setting targets, measuring efficiency, and planning factory production. Formulas are provided for calculating basic time and SMV from observed cycle times under different conditions.

3. The Main objective of industrial engineering
is:
• To Increase Productivity
• To eliminate waste and non-value added activities
• To come up with the optimum use of scarce resources that would bring out
the best results.

4. Importance of SMV in the Apparel
Industry
• SMV is calculated for doing a costing of garments
• It is used for calculation of target and set the right target
• For Calculating the Efficiency of workers
• SMV is calculated for making a plan and take effective factory production
decision.

5. Formulas of SMV Calculation

6. Calculation of SMV in Garments
• SMV = (Basic Time + Allocated Allowance)
• The formula of Basic Time = Observe Time x Rating Factor
• Basic Time: Basic time is the most likely time required to make garments
considering observe time and applicable rating factors.
• Observe Time: Time taken to do a work when an observer is observing
closely and record the worker’s work speed.
• Calculation of Observe Time = Total Cycle Time is divided by Number of
Cycle

7. • Cycle Time: Cycle Time is the time between starting a garments manufacturing
and finishing of those garments.
• Rating Factor: Rating factor is assigned based on an evaluation of worker
performance which is conducted through eye judgment. A worker can be fast,
slow and rating is on a scale of 100% to lower.
• Costing SMV is calculated for sending SMV information to buyers. Normally 5%
additional time is added with the actual SMV.
• Costing SMV = Actual SMV + (Actual SMV x 5%)
