You’ve probably seen them before — those project spreadsheets in which Year 2 revenue is Year 1 revenue plus 10%, and so on. These projections are rarely accurate, because they reduce the world to linear models — when in reality the growth process is nonlinear, sometimes even exponential. Instead of assuming that growth will happen right away, and at a steady pace, think about the likely times at which revenues will be realized. What’s the realistic lag time between initiating your growth project and reaping the rewards from it? Focus on three inputs: the revenue goal for the investment at steady state; the assumed first-year revenue; and the inflection point, which is the time required to reach 50% of the revenue goal. Unrealistic revenue projections can lead to career-ending misses. So take plenty of time to do some smart thinking beforehand.
