I recently was at a Target Superstore on a summer Sunday and they were totally out of regular Coke cans. This would seem to me to be a staple item that you could count on to be there whenever you shopped, but there were none. Not on the shelves, not on the end caps, not on the display in front of the store.
If you looked at the space allocated for Coca-Cola branded beverages, it was substantial, but the square footage was taken up with Coke Zero, Caffeine Free Diet Coke, Cherry Coke Zero and other variations that did not sell. So many choices and flavors added to the complexity but detracted from the core.
Coke is the #1 selling pop and Diet Coke is #2* yet Target and Coca-Cola diverted their attention and lost (at least some) sales because they focused on niches at the exclusion of the main products.
Think about the offerings your organization provides. Are you making your version of Coke and Diet Coke as robust as they could be or are you pushing Cherry Coke Zero only to find it still sitting on the shelf? You may find that a narrow focus is more refreshing.
