  • Co-developer of structured analysis/design methods that influenced software development for most of the 1970s and ’80s

“There is nothing in the programming field more despicable than an undocumented program.” (“Techniques of Program Structure and Design,” 1975)

“A system composed of 100,000 lines of C++ is not be sneezed at, but we don’t have that much trouble developing 100,000 lines of COBOL today. The real test of OOP will come when systems of 1 to 10 million lines of code are developed.” (“Object-oriented Programming Systems, Languages and Applications,” Andreas Paepcke , 1991)

“If you haven’t spent at least a month working on the same program — working 16 hours a day, dreaming about it during the remaining 8 hours of restless sleep, working several nights straight through trying to eliminate that ‘one last bug’ from the program — then you haven’t really written a complicated computer program.” (“Just Enough Structured Analysis,” 2006)
