Abstract:

Problems faced by programmers who must maintain programs someone else wrote were identified. They were reduced to three fundamental inhibiting factors 1 the limited rate at which people can make relevance tests, 2 over-confirmation in clues required before hypothesis-testing, and 3 human vulnerability to distraction and procrastination. Studies suggested collectively by these factors were conducted. The studies 1 ascertained that programmers tend to think in terms of conceptual groupings whose objective identification would be helpful, 2 indicated that it was feasible to trace the path the programmer takes as he prepares to make a modification, and 3 identified a few tentative measures of the degree of maintainability of computer programs.
