(1974) Increasing Complexity — As an E-type system evolves its complexity increases unless work is done to maintain or reduce it.
NettetBeginning in the 1970s, Manny Lehman and his colleagues studied the evolution of software systems. They identified a set of behaviors that became known as Lehman's laws of software evolution.
