Cut through the clutter and the noise, don't add to it.
Competition has never been fiercer. Markets have never been more crowded. Your business has never been under so much pressure. Margins are slim and getting slimmer, while quality demands keep rising.
Don't waste valuable resources developing products or service lines which simply cannibalize your existing business. Take the time to understand your target market well, and hone your product portfolios and distribution channels accordingly.
