There's a malady we see quite a bit in this business. We call it "chasing the flavor." It happens when sales and marketing executives are constantly dropping one initiative for the latest flavor of the month. One month it's 3-D videos. The next, they've forgotten about the videos and are onto Twitter or sales incentive programs or giant inflatable pink gorillas. All valid ideas (ok, not the gorillas...), but none of them will ever work if you keep chasing the flavor.
It's impossible to know if a new marketing or sales initiative is working after a few weeks or months. Sales people have to adapt, dealerships and distributors need to adjust and customers need to be educated. Runaway successes are rare in this world. You put the program into action because the strategy was sound and the numbers made sense. Trust yourself. You'll be glad you did.
