In general, the invention is directed to techniques for developing an enterprise planning model in cascaded planning stages. For example, an enterprise planning system receives data that defines an enterprise planning session from a set of analysts in cascaded planning stages. The analysts associated with each subsequent planning stage refine the enterprise planning model defined by analysts associated with previous planning stages. In this manner, the set of analysts may define an enterprise planning model that may allow large, diverse organizations to establish planning standards across dozens or hundreds of business units, while allowing the business units to extend the planning standards to further refine the planning sessions.
