Root Cause Failure Analysis: Workshop and Simulation Training

Introduction:

Root Cause Failure Analysis: Workshop and Simulation Training Course Hands-on

Throughout the Root Cause Failure Analysis: Workshop and Simulation Training course, you will learn how to apply the techniques taught to your own on-the-job RCFA investigations through a series of industry failure analysis case studies that highlight the investigative techniques, roles played by key characters in the analysis activity, the analytical approach, and the types of failure causes that can contribute to the failure. The Root Cause Failure Analysis: Workshop and Simulation Training class will also undertake a comprehensive simulation of a real-life root cause failure investigation, working in teams to analyze a relatively complex case scenario, conduct role plays and interviews, develop a root cause failure report, and present it before the class.

This action-learning program, one of the most comprehensive in the industry, teaches both the theory and practice of root cause failure analysis. It includes numerous exercises, several case studies, and one major case study that simulates in-class the workings of an actual RCFA investigation including the team dynamics and interpersonal communications aspects.

We will discuss brainstorming, Ishikawa diagrams, mind mapping, flow charting, fault tree analysis, event and causal factors analysis, barrier and change analysis, MORT analysis, critical incident approach, and several other techniques for defining potential causes of the problem. We go on to discuss failed hardware evaluation technologies, design of experiments, and other technologies for converging on the actual cause of the failure. We will then discuss potential corrective actions, including guidance for selecting the best solution.

Customize It:

With onsite Training, courses can be scheduled on a date that is convenient for you, and because they can be scheduled at your location, you don’t incur travel costs and students won’t be away from home. Onsite classes can also be tailored to meet your needs. You might shorten a 5-day class into a 3-day class, or combine portions of several related courses into a single course, or have the instructor vary the emphasis of topics depending on your staff’s and site’s requirements.
