Phase 2—Forecast-based planning: As annual budgets become less useful at stimulating longterm planning, managers attempt to propose five-year plans. At this point they consider projects that may take more than one year. In addition to internal information, managers gather any available environmental data—usually on an ad hoc basis—and extrapolate current trends five years into the future. This phase is also time consuming, often involving a full month of managerial activity to make sure all the proposed budgets fit together. The process gets very political as managers compete for larger shares of funds. Endless meetings take place to evaluate proposals and justify assumptions. The time horizon is usually three to five years.
