Too often when things aren't going right in your Business, you tend to focus on where you think the problems lie and come up with a solution in isolation to what's going on elsewhere in the company. It would be like getting a prescription from a doctor without first having a consultation about your symptoms to see what else is going on.
The same applies in business; don't potentially misdiagnose the problem without all the facts. So how can you keep a close eye on all the facts?
