Search available knowledge bases for an existing workaround.  Determine if a workaround for the problem can be found or requires a workaround to be created. 

A simple workaround may be implementable to help with the availability of the IT service until a full resolution is available to completely resolve the problem. 

Do not spend too much time finding or creating a workaround when the priority is to determine the root cause and provide a full (permanent) solution for the problem.
