Work study
Work study is the systematic examination of the method of carrying activities. It is one of the important tool to improve productivity in textile and apparel industry. Work study investigates the work done in an organization and aims at finding the best and the most efficient way of utilizing the available resources (man, material, money and machinery) to achieve best possible quality work in minimum possible time.

Formula used for calculating different parameters for work study:

Observe time X Observe rating
1. BMV = ………………………………………..
Standard rating

2. SMV = BMV + 0.03 + 15%

Operator X WH X 60
3. Target = ……………………………. X Want
SMV

Daily production X SMV
4. Efficiency = ………………………………………… X 100
Working min X (Operator + Helper)

60
5. Standard Capacity = ………………………………….
Observe time X 1.66

Total production X SMV
6. Overall performance = ………………………………………..
Clock min

SMV
7. Performance = ……………………………………………………….. X 100
Actual time (Observe time + 03 + 15%)

Total production X SMV
8. True performance = …………………………………………………… X 100
(Total operator X WH X 60)?ineffective time

9. Input hr = Total operator X WH

Total production X SMV
10. Output hr = ………………………………….
60

11. Clock hr = No. of operator X Working hour

12. Clock min = No. of operator X Working min

Total man power X 60
13. Required SMV = ………………………………….
Line target/Hr

SMV
14. Utilization% = …………….. X 100
