The motto for strategic planning used to be “Think long-term!” —five, ten, fifteen years out.
Throw that old adage out the window. It never really worked, and now we don’t even have the illusion that it might. No one can predict that far out anymore. If weather forecasts are relatively unreliable more than three DAYS out, what makes you think you can predict global markets, the vagaries of customer tastes, the pace of technology change or the moves of competitors?
