This data-gathering approach, employing multiple sources of information,
enabled us to triangulate our research to ensure that we understood both the formal
and informal aspects of the current institutional arrangements (Jick 1979).
In the description and analysis that follows, all of our sources support the interpretation
given unless we explicitly note to tbe contrary. Finally, as part of our
analysis, a draft of this paper was circulated to our informants. Their feedback
confirmed we had described tbeir ACU correctly. Further, the feedback did not
take issue witb the substance of our analysis.
