I agree that too many people start throwing technology at their problems without even understanding the source. I've seen cases time after time where administrators don't have a clue as to what is happening on their network.

The problem starts with the prevailing flaw in the market: I need Internet. Most business leaders haven't even sat down and thought (hard) about why they need it. Is it for improved communications? Expanding markets? Is it for employees to have fun and shop? If leadership hasn't identified specific business applications and ROI justification, then evaluating WAN problems is only the beginning of the problems. In most cases, execs are burning way too much cash and have nothing to show for it...except problems and liabilities.
