The project began in 1978 as an effort to create a more modern version of the then-conventional design epitomized by the Apple II. A ten-person team occupied its first dedicated office, which was nicknamed "the Good Earth building" and located at 20863 Stevens Creek Boulevard next to the restaurant named Good Earth. Initial team leader Ken Rothmuller was soon replaced by John Couch, under whose direction the project evolved into the "window-and-mouse-driven" form of its eventual release. Trip Hawkins and Jef Raskin contributed to this change in design. Apple's cofounder Steve Jobs was involved in the concept.
