Direct Efficiency and Productivity

To define few Key Production Performance Indicators (Production KPIs)

◦ OEE (Overall Equipment Effectiveness)

◦ Direct Efficiency

◦ Productivity

Agenda

Direct Efficiency

Direct Efficiency & Productivity

Productivity

Efficiency of workers involved in production activity onlyEfficiency and effectiveness of all the workers enrolled in the company

Efficiency ?? Effectiveness??Ratio of input and outputAbility to do thing correctly

Why Direct Efficiency & Productivity ?

Direct Efficiency= h𝑇 𝑒𝑜𝑟𝑒𝑡𝑖𝑐𝑎𝑙 𝑃𝑟𝑜𝑑𝑢𝑐𝑒𝑑𝐻𝑜𝑢𝑟𝑠𝑊𝑜𝑟𝑘𝑒𝑑𝐻𝑜𝑢𝑟𝑠

Lets see an example

Punching (2 min)

Trimming (1 min)

Drawing (3 min)

Buffing (2 min)

Packaging (2 min)

Cutting (1 min)

Deburring (1 min)

Drilling (3 min)

Bending (5min)

Washing (2 min)

(b)

Process Flow Total Time

10 min

12 min

Thus we have Total Time Cycle for Process (a) TTCa =10 minutes Total Time Cycle for Process (a) TTCb =12 minutes

Standard Hour (Item (a) STHa= (10/60) =0.1667 hrs/unitStandard Hour (Item (a) STHb= (12/60) =0.2 hrs/unit

Production Hour= (STHa*Qtya) + (STHb*Qtyb= ((10/60)*180)+ ((12/60)*100)= 50 hrs

.Net Shift Time(NST)=Shift Time-Break Time

=8.5 -0.5= 8 hrsDirect Presence Hours= (NST*TP)+OT-SL

= (8*10)+1-4 = 77 hrsDelegated Hours = Sum(all delegation man-hours)

= 20 hrsWorked Hours = D.Presence Hrs- Delegated Hrs

= 77-20 = 57 hrs

Paid Hours=(ST*TE)+OT-SL =(11*8.5)+1-4 = 90.5 hrs Direct Efficiency= h𝑇 𝑒𝑜𝑟𝑒𝑡𝑖𝑐𝑎𝑙 𝑃𝑟𝑜𝑑𝑢𝑐𝑒𝑑𝐻𝑜𝑢𝑟𝑠
