What is the minimum recommended length of a Growth-Driven Design engagement?

A Growth-Driven Design (GDD) engagement is recommended to be a minimum of six months to allow sufficient time for the iterative process of research, planning, building, learning, and adapting. This duration ensures that enough data can be collected and analyzed from user interactions with the launch pad website to inform meaningful improvements and achieve measurable results. Three months is generally too short to complete multiple cycles of the GDD process and see significant impact. While nine months could also be effective, six months is considered the minimum to establish a robust GDD rhythm. Four months, like three months, often doesn't provide enough time for comprehensive learning and iteration.
