Its not just Bunnings management - many retailers use supply chain logistics and stocking level software with preset levels for minimum stock holding, reorder stock levels etc. The local floor, inventory and store manager's on the ground experience and intuition no longer has any sway. What is worse they cannot easily modify those preset levels or seasonally adjust them to accommodate extraordinary phases such as the local footy team is having a blinder of a season and everyone wants in on the bandwagon with their branded merchandise. They have to rely upon a "merchandise team / buyer" from afar who rarely listens to their input.
Personally I'm not in the retail game but I'm observant and have had many friends who are in the retail trade. You don't have to be real bright to know that surf rods, alvey reels, snow gear (clothing, skis etc), gas space heaters, deep sea winches, waders, fly fishing gear, ..... are going to be very slow moving stock in the tropics. Then when you ask staff when are they going to be reordering more of a range of very popular leading brands of fishing lures the response is we are waiting for the computerized ordering system to catch up, when it does we sell out in a few days, just keep an eye out for when they come in. Local staff loose out on potential sales hence their sales quotas and bonuses are affected.
Retail management stupidity, stock on hand you can't sell, and empty shelf space in their potentially leading sellers - but they will never know or learn because the store can never sell more than what they receive therefore the stock levels are not adjusted upwards.
Then you see the bastardry that went on with the MIK franchisee's who were conned into ordering and purchasing stock levels that were always grossly optimistic to the point of being fraudulent advice. Most of that stock was still there when those franchisee's went under. I've seen stock in closing down sales that has been in a store for ten years or more.
