Please view excel sheet.
1-Purchase is at blew the standard value. this might be due to efficiency in purchasing by purchase department.
2-Company might have purchased bulk quantity resulting discount on purchase of bulk quantity.
3-Materials prices decreased unexpectedly in the market.
1- Inexperienced workers. Inexperienced labor will take time to produce the product which will lead to decrease in production of number of units in a specified time.
2- Frequent breakdowns leads to wastage of time. waste of time has direct impact on in shape of less no. of units produced.
3-Shortage of raw materials leads to breakdown in production due to shortage of raw material and ultimately efficiency get effected due to breakdown.
