Today is a result of past actions. Today is necessary for understanding and evaluating current status and what are the obvious and hidden reasons for it. Today helps to develop strategies for immediate use. It helps to define steps you have to do right now to reach desired status in shorter and longer future.
Tomorrow is near future. Definition of time scale for tomorrow depends on the state, size and background of your business. It can vary from several weeks to several years. Tomorrow stands for short-term future and is linking Today with Future.
In future is a time dimension for long-term planning. Future is logical result of today and tomorrow, but we always have to keep in mind possibilities of unexpected and unpredictable events. Inventing scenarios for future and different action plans could be a good idea.
