Objective 3 – Escalation

Reference: Your companies procedures

When presented with a problem it is important to understand the scope of your

responsibility and to determine when it is time to escalate the problem to a supervisor or to

a ASM engineer.

Preparation

Discuss your own escalation procedures with your Instructor.

Some questions you may ask in your company are:

How long can I spend on a problem before I escalate?

What documentation should I refer to when diagnosing a problem?

Do I need to record any incidents that lead to machine downtime?

Which personnel are on my escalation list and in which order should they be contacted?

Demonstration

Draw an escalation chart on the following page. Show the names and extension/pager

numbers for the individuals responsible for production, process and machine issues if

these are known by you at this time.
