When customers lie
An analysis is only as good as the data that you can get. We had a customer who did not allow access to their systems and gave invalid info. The cusotmer tech people specifically said they did NOT use a proxy server. When they had issues with the software after we installed it, we spent a week tracking the problems down. We had to write a special routine to trap some transaction data that is normally not usefed by our product. Analyzing that data showed they used a proxy server, which they finally admitted to. This was nothing big, the configuration just needed to be revised for the proxy server. But we spent a week (at our cost) chasing a problem that should not have been a problem. Analysis is good but when you can't get the data, or youget bad data from the customer, then the analysis is flawed.
