In our work to help firms pick Performance Management technology, we have seen a resurgence of an old trend - the loudest voice wins.
This phenomenon is most often found when company leaders assemble a financial systems "software buying group" with loose leadership. Normally this group attempts to work together, building requirements, interviewing software vendors, watching various demos all with the best of intentions. Then they start to suffer from direction by the loud folks. The interesting part is that often the louder ones haven't been listening much -- so they can have the least idea of what their company should be doing.
Of course, it is never our attempt to make a decision for our clients, but certainly to help them find the best decision. Thus we tend to work to make all voices heard -- often the quietest folks are the most perceptive.
