Best Practices Analyzer emerged after Microsoft observed certain patterns when addressing critical situations with its support services. Critical situations require urgent assistance to solve a problem that’s disrupting service to an organization’s members and its important business operations. What Microsoft found was that not only were the number of critical situations growing, but that 60 percent of them were caused by configuration errors, not bugs in Exchange. Moreover, new critical situations arising in some shops were the same ones that had emerged in other organizations just a few months earlier.

Microsoft began by creating a utility to gather key information throughout an Exchange environment. When a customer faced a critical situation, they were told to run the utility and Microsoft would sift through the data to ferret out the root cause of a problem.

Collecting data was only the first step. Next, an engine was developed that could analyze the data and expose it to a set of rules. The rules established thresholds. If a key data item was outside the acceptable range in a threshold, the rule would “fire” and a red flag would be raised for support folks.
