Task 1: Get the Facts
Task 1: Get the Facts
The first step in solving any problem is to get the facts. Although it is tempting to
speculate about causes, your time is better spent in first understanding the symptoms
of the problem.
Task 1a: Determine the Facts About the Problem
To get a clear, complete description of problem symptoms, ask questions to determine
the facts about the problem. For example:
Task 1b: Determine the Facts About the Situation
Collect facts about the situation in which the problem arose. A clear description of the
situation that led to the problem could indicate a simple solution. Examples of
questions to ask are:
•
Who reported the problem and how can this person be contacted?
•
How critical is the situation?
•
What events led to the problem?
•
Has anything changed recently that might have caused the problem?
•
What event messages have you received?
•
What is the current configuration of the hardware and software products affected?
