LisaProject was the first GUI-based project management software. Developed for the Apple Lisa computer, LisaProject was conceived and implemented by Debra Willrett of SoloSoft and developed for Apple's Lisa computer. In 1981, Willrett realized that project management was a universal problem and that a GUI-based application would be a useful tool. She proposed what became LisaProject to Trip Hawkins at Apple. At the time, Apple was developing the Apple Lisa computer which had limited software.
