The GROS funnel is an easy way to visualize and manage the critical decisions and progress of projects (innovations, activations, campaigns, ...). A project is divided into distinct phases separated by decision points. Each phase has its clear input and desired output. For every type of business, the necessary phases might be (slightly) different. At the end of each phase, continuation is decided by a manager, steering committee or governance board. He/ she has only 4 possible answers: Go, Recycle, On Hold or Stop. Some projects with immediate impact & requiring minimum resources can take the light or express shortcut.
