Using the ideas generated in "Brainstorming," "Develop Concepts" describes a process the design thinking core team uses for turning single ideas into creative solutions. Also included in this nine-minute video are tools for the core team to use in developing concepts from the brainstorming ideas. This video is part of the Design Thinking video series meant to accompany any one of three cases (Arena Industries [UVA-S-0240], Trenton State College [UVA-S-0241], or Great Lakes [UVA-S-0248]) that explore the design thinking approach to innovative problem solving.
