Is it necessary to monitor promotional/marketing strategies?
Yes, because without regular evaluation of promotional and marketing strategies you will not know the effectiveness of your efforts in these areas. If you are putting money and effort into a marketing strategy that is not producing the results you want, stop and re-asses the situation to see if your money and efforts could be better channelled in another way. Always compare your target sales with your actual results, as this will give you an indication if you are getting the results you want.
