According to Newton's First Law, objects at rest tend to stay at rest, while objects in motion tend to stay in motion (unless acted upon by an unbalanced force). As instructors, we must apply that unbalanced force to ensure that students do not fall prey to the planning inertia that plagues so many start-ups. The prevalence of business plan competitions and courses requiring a formal plan obscures a potentially troubling fact: researchers do not agree on the relationship between a completed business plan and new venture success. Some believe that a plan takes time away from more valuable activities; others argue that a plan helps facilitate resource acquisition and management, making goals more achievable. We believe that planning is useful primarily as a tool to create momentum for the new venture. We thus propose an interactive panel discussion in which we address start-up planning as an exercise in momentum generation.
