Redesign process - analyzing and evaluating potential future-state scenarios. Once the AS-IS model is established, it is time to build TO-BE models as potential scenarios of future conditions and compare them with the current reality. To do this it is important to frst establish and prioritize which variables will present the key factors in the analysis. These variables could be inventory costs, transportation costs, required service levels, ordering costs, labour availability, etc. The model of the new redesigned process has to contribute to simplifcation, minimization and automation of steps,and effciency optimization through using new information technology.
