Diagnostics of management and organisational systems

Agricultural Economics (AGRICECON), 2006
The term "diagnostics" is normally used to refer to the process of identifying some incorrectly operating components in a particular system. The fault symptoms are, however, usually discovered in a different part of the system than that in which the ...
