This document discusses the importance of co-designing spaces through involving end users in the design process. It notes that while co-design can make projects messier, it significantly improves user satisfaction and productivity. The document outlines some of the unexpected challenges ("gorilla problems") that arose during one co-design project, and how limited resources were allocated to address them. It also discusses how to manage the emotional aspects of change by understanding the stages of reaction and tailoring communication approaches. The key message is that co-design, while complex, ultimately leads to higher morale and better outcomes through increased user involvement and control.
