Task 2: Find and Eliminate the Cause of the Problem

Example

This is an example of information you might learn from asking questions like those in 
Task 1.1:

Task 2: Find and Eliminate the Cause of the Problem

After you collect your facts and log the problem on your worksheet, you are ready to 
begin considering the possible causes of a problem.

If you rely on your knowledge and experience, the facts you have collected about the 
situation, and facts you have collected about the problem, you can begin to list possible 
causes of the problem.

Task 2.1: Identify the Most Likely Cause

To evaluate the possible causes of any problem, you must compare each with the 
problem symptoms. Using the problem-solving worksheet gives you a guide for 
accomplishing this task. In this example:

•

Possible causes become column headings.

•

Entries you have made in the worksheet’s rows indicate whether the cause in 
question could have produced the problem symptoms you listed on the left.

•

Write “yes” in the appropriate box if a possible cause explains a fact.

•

Write “no” in the appropriate box if a possible cause does not explain a fact.

•

The most likely cause is the one that best explains all the facts, that is, the cause 
that is answered “yes” in many spaces in the column.

Example

Possible causes of the hung terminal problem in the above example could be:

•

A terminal hardware problem

•

A stopped or suspended TACL process

•

System security, which locks a user out after three unsuccessful logon attempts

Question

Answer

What is happening that indicates 
a problem?

A terminal is hung.

Where is this problem 
occurring?

In the office of USER.BONNIE. The affected terminal is 
named $JT1.#C02.

When is this problem occurring?

At 8:30 this morning and also at the same time two days 
ago. Both times, this occurred after three unsuccessful 
attempts to log on.

What is the magnitude of this 
problem?

Intermittent; the problem seemed to disappear on its own 
when it first occurred two days ago.
