the productivity for 150pcsby 16 persons 0.368pcs/sec 9.37pcs/per
For per day Time productivity person productivity
For 275pcs23 person 1.136 pcs/sec 11.96 pcs/per
For 300pcs25 person 1.303 pcs/sec 12 pcs/per
Forecasted productivity summery
Actual productivity summery

13. PRODUCTIVITY CALCULATION CONT.
Marginal changes
Decision: we can find that any marginal change in person
productivity when we use 20 perso for producing
250pcsthen person productivity will 11.95pcsper person
When 1 unit change that is 21 person producing
251pcsthen person productivity will be remain same but
the time productivity will be changed by 0.0035 pcs/sec.
so we should not go for marginal change.
