Course Description

ITM is a 32-hour workshop that explores the principles and application of effective troubleshooting methods. This workshop begins with a review of Safety and upset condition hazards. Participants then explore some of the basic troubleshooting methods used to streamline the problem-solving process including the 7 step troubleshooting methods used and perfected by the Navy Nuclear Technical Training Division. We will explore differential comparison methods and then move into future failure avoidance by examining RCA methods designed to prevent repeat failures.

Prerequisites

No course pre-requisites. Course is suitable for all maintenance personnel and leadership roles.
