Determining the Cause of a Problem: A Systematic Approach

Continuous availability of your NonStop system is important to system users, and your problem-solving processes can help make such availability a reality. To determine the cause of a problem on your system, start by trying the easiest, least expensive possibilities. Move to more complex, expensive possibilities only if the easier solutions fail.

This subsection presents an approach you can use in your operations environment to:

•

•

•

Determine the possible causes of problems Systematically fix or escalate such problems

Develop ways of preventing the same problems from recurring

The four basic steps in systematic problem solving are:

Task	Page
Task 1: Get the Facts	1-6
Task 2: Find and Eliminate the Cause of the Problem	1-7
Task 3: Escalate the Problem If Necessary	1-8
Task 4: Prevent Future Problems	1-9

A Problem-Solving Worksheet

Table 1-1 is a worksheet that you can use to help you through the problem-solving process. Use this worksheet to:

•

•

•

•

Get the facts about a problem

Find and eliminate the cause of the problem Make any appropriate escalation decisions Prevent future problems

Make copies of this worksheet and use it to collect and analyze facts regarding a problem you are experiencing. The results might not tell you exactly what is occurring, but they will narrow down the number of possible causes.
