Gerald M. Weinberg, as quoted in Larman, Craig (2003. június 1.). „Iterative and Incremental Development: A Brief History”. Computer36 (6), 47–56. o. DOI:10.1109/MC.2003.1204375. ISSN0018-9162. „We were doing incremental development as early as 1957, in Los Angeles, under the direction of Bernie Dimsdale at IBM's Service Bureau Corporation. He was a colleague of John von Neumann, so perhaps he learned it there, or assumed it as totally natural. I do remember Herb Jacobs (primarily, though we all participated) developing a large simulation for Motorola, where the technique used was, as far as I can tell ... All of us, as far as I can remember, thought waterfalling of a huge project was rather stupid, or at least ignorant of the realities. I think what the waterfall description did for us was make us realize that we were doing something else, something unnamed except for 'software development.'”
