Within this study we highlight some key milestones that indicate readiness to move from natural to structured development and back depending on the stage of prototype readiness and team makeup. For example, we find that a company is poised to move toward a structured process if the company has completed a design, verified market fit, and started to hire new employees or begun to work with multiple outside partners or vendors. On the other hand, as demonstrated with the case study of C.44 (Fig. ), if a company is pivoting toward a new market or completely new design, a reversion to natural development is recommended to avoid costly slowdowns.
