Evidence suggests that small firms benefit from business planning as new ventures are assessed and started. Yet relatively few make use of business planning, or go about such planning in an inconsistent way that invites errors and omissions. This paper presents a systemized web-based venture planning model that provides opportunities for entrepreneurs to collect the appropriate information and assess their ventures. This model is based on the stage gate theory of new venture management and provides self-motivated feedback progressively over a series of stages. Each stage represents a unique level of analysis crucial to accepting or rejecting proposed ventures. In the process of completing the model, a business plan is created.
