1. A method for facilitating in assessing transitional costs in business transformations using a computer-aided organizational design system, the method comprising: creating a first organization design model representative of the current organization design state of an organization using a graphical tool identifying a first plurality of roles and the relationships among the first plurality of roles with respect to each other and at least one of a first plurality of tasks respectively designated to each of the first plurality of roles, each of the first plurality of tasks having at least one of a first plurality of tools is configured to correspondingly perform one of the first plurality of tasks; changing the first plurality of roles in the first organization design model to a second plurality of roles by adding another role, combining or splitting one or more of the first plurality of roles, or both, in the first organization design model and changing the first plurality of tasks to a second plurality of tasks by designating another task, eliminating one or more of the first plurality of tasks, or both in the first organization design model forming a second organization design model, one or more of the second plurality of tasks is correspondingly designated to one of the second plurality of roles; and generating a report identifying at least one of a second plurality of tools having a skill level necessary for each of the second plurality of roles to correspondingly perform one or more of the second plurality of tasks designated for each of the second plurality of roles, identifying the relationships among the second plurality of roles, and identifying a transition cost for each of the second plurality of roles when moving from the first organization design model to the second organization design model, the transition cost is determined based on predetermined calculation algorithms or heuristics.
