Team WIKISPEED is an Agile hardware and engineering company, using Test First development practices run by Scrum teams to produce road-legal cars, microhouses, and social good projects. Joe leads WIKISPEED, a team of 500 volunteers in 20 countries, and walks us through how their 100-MPG road car was made possible in just three months through object-oriented design, iterative development, and Agile project management. Joe worked with the team at Scrum, Inc., to share these learnings, and now he shares his experience report on exactly how Agile from software projects is applied to physical engineering and manufacture, and how cross-functional software team members can blow up the constraints we imagine around traditional manufacturing. Joe will use the example of the design and development of their ultra-efficient, modular cars and clients' projects in satellites, laboratory equipment, missile systems, radio systems, medical devices, and others.
