Total standard time for body processes
594”

Average Process Time Calculation Method:

Average process time,
= (594/19)
= 31.26”

Calculation of BPT, UCL, LCL, Organization Efficiency & Production Target Per Hour:

Production target per hour with 27 operators,
= {(27×3600×0.85)/594}
= 139pcs per hour

Again,
Bottleneck time= 26 second,

So,
Production per hour,
= (3600/26)
= 138pcs per hour.

Now,
Basic pitch time (BPT) is,
= (594/27)
= 22”

Again,
Upper control limit (UCL) is,
= (22”/0.85)
= 25.88”

Again,
Lower control limit (LCL) is,
= {2 × (BPT-UCL)}
= (44-25.88”)
= 18.12”

Now,
Organization efficiency is,
= (BPT/Bottleneck time)
= {(22”/26”) × 100}
= 84.66%

Again,
Direct productivity is,
= (138/27)
= 5.11 pcs per operator per hour

Total standard time for collar, cuff & sleeves
422”

Average Process Time Calculation Method:

Average process time,
= (422/24)
= 17.58”

Calculation of BPT, UCL, LCL, Organization Efficiency & Production Target Per Hour:

Production target per hour with 19 operators,
= {(19×3600×0.85)/422}
= 143pcs per hour

Again,
Bottleneck time= 24 seconds,

So,
Production per hour is,
= (3600/24)
= 150pcs per hour

Now,
Basic pitch time (BPT) is,
= (422/19)
= 22.21”

Again,
Upper control limit (UCL) is,
= (22.21”/0.85)
= 26.13”

Again,
Lower control limit (LCL) is,
= {2 × (BPT-UCL)}
= (44.42-26.13”)
= 18.29”

Now,
Organization efficiency is,
= (BPT/Bottleneck time)
= {(22.21”/24”) × 100}
= 97.66%

Again,
Direct productivity is,
= (150/18)
= 8.33 pcs per operator per hour
