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:
