Dear Rudradeva,
If you are from manufacturing company, then for your business the following costs are important:
a) Inventory Carrying Cost of Raw Materials
b) Work in Progress (WIP) Inventory Costs
c) Inventory Carrying Cost of Finished Goods
d) Capital costs to run the operations
e) Capacity costs
f) Maintenance costs
g) Quality costs
h) Inspection costs
Therefore, your focus should be on controlling the above costs and not on number of training hours per se. Controlling the above costs may demand training for more than 40 hours. Therefore, you may decide your priorities on the business requirements or hours of the training.
Thanks,
Dinesh Divekar
