  1. marks)
  • Know your customer: In order to provide the best service possible, IT needs to know everything about the customer.  And they shouldn’t have to run around tapping various databases to get the full picture.  Instead, they should look into something like a configuration management database (CMDB) to quickly get an aggregated, data-rich view.
  • Knowledge management: This should be considered table stakes when it comes to service as it allows IT to maintain expertise and domain knowledge even when an expert transitions off the team. With a strong knowledge base in place, IT can ask the right questions and find a solution quickly.
  • Do-it-yourself intelligence: There’s nothing wrong with sharing this knowledge with customers as well. Today’s typical end user is far more sophisticated than even five years ago, and many people like to do it themselves for faster resolution. Knowledge from previous incidents can be quickly filtered down to the relevant information and presented to the customer in an easy-to-search database.
  • Risk mitigation: Sometimes the best service for a customer is service they don’t even know they’re getting. By following the above with the right technology, technicians can analyze the potential impact of an incident using multiple sources of data from across the business.
