Answer:
Possible causes of material quantity variance:
1. The use of sub-standard material
2. The use of unskilled labour
3. Wastage of material
Explanation:
Material quantity variance is the difference between standard quantity and actual quantity used multiplied by standard price. The use of sub-standard material reduces the quality of output thereby resulting to unfavorable material quantity variance. The use of unskilled labour also leads to unfavorable material quantity variance. Wastage of material due to low quality of inputs also results to unfavorable material quantity variance.
If your a busy small business owner, taking time away from your store makes you less efficient. The trade offs for using this premium service are 1. your spending more money 2. control over quality. Vise versa if your paying more for the “best groceries” then that may not be an issue. Also be aware that another issue is stocking, going to the store yourself does not guarantee that the store will have all items in stock when you go. 3. Time, taking time to grocery shop takes away from your business or the cost of an employee to watch the business or do the shopping for you having you rely on a third party’s judgment. 4. Gas, the cost of gasoline to go to and from the store. If all these are added up then you are essentially paying more for your “in person” groceries as it is. Choosing to grocery shop yourself saves you money (although how much? Once everything is taken into account?) but again the time it takes away is significant. For a busy small business owner time is extremely important and this is why the trade off of cost or added expenses for groceries may be worth it. (I hope this helps guide you in answering this question).
