If your newsagency software allows it, next time you are reporting on business performance select a supplier comparison view. This can highlight strengths and weaknesses a more traditional view of business performance make be hiding from you.
Take your gift department, the traditional analysis will be to look at sales by product category or occasion. Switching to a supplier view could bring to your attention a supplier level relationship that is not working for your business.
I did this recently for a newsagency as part of a business review. Two suppliers are not delivering results for the business and this was being missed as gifts overall are up more than 25% year on year whereas for these two suppliers, sales were only up 5%.
Sometimes, changing a data view can valuably alter your view of your business.
