There's been plenty of research on why organizations go bad and turn corrupt. but how do you rebuild them after the legal and ethical breaches?

In this paper out of the Academy of Management Review, After The fall: Reintegrating The Corrupt Organization, the authors put forward a four stage process: discovering the transgression, explaining it, serving penance and rebuilding the organization's processes.

It's an interesting study. The only question I would raise, however, is whether the model has actually been tested. There are some organizations where the culture of corruption is too strong. In those cases, it's like groundhog Day. Things just keep drifting back into the corrupt state.
