This reminds me of a 1976 article written by David Parnas and Harald Würges: Response to undesired events in software systems. Since it's old, it is harder to find, but here are a few things to try: If you have download privilege on ACM Digital Library, http://portal.acm.org/citation.cfm?id=800253.807717 (If not, you can still see the full citation, the abstract, etc.) The paper is also collected in this book full of Parnas's papers: Software Fundamentals: collected papers by David L. Parnas. Edited by Daniel M. Hoffman and David M. Weiss. Someone else made slides to present this paper: http://www.cs.virginia.edu/~wh5a/personal/Quals/misc/ParnasPaper%20on%20stan...
