Reliability happens at the point of DECISION

Reliability doesn’t just happen. Following standards, doing what worked 10 years ago or any other approach to reliability engineering that doesn’t focus on what your system is today won’t make reliability happen.

Fault trees are great at modelling system reliability. They are one of several tools that can help you turn what you know about component or subsystem failure characteristics into an understanding of system reliability characteristics. Which lets you measure reliability.

But measuring reliability is one thing. Improving reliability is a much bigger thing.

Good reliability decisions are based on 
knowing HOW your system will fail

Fault trees are a great Root Cause Analysis (RCA) tool. They can really help you and your team identify the potential causes of failure, which then focuses your investigation on what really happened.

But it is much better to prevent failures from occurring. Making your first design a reliable design means you need to know how your system will fail … from the first day of design.

Fault Tree Analysis (FTA) is a great 
tool for working this out

Course Description and Overview

The 4-hour, 11-module Fault Tree Analysis (FTA) Course teaches you how to use fault trees to achieve important outcomes supporting reliability performance.

Fault trees are visual representation methodologies that represent our understanding of how faults progress to a state of failure. 

Fault trees can be used to model system reliability where the reliability performance characteristics of components are used to determine system reliability performance characteristics. This allows us to model Time to Failure (TTF) at a system level if we have a good understanding of component TTF. This can then be used to inform things like warranty period determination or reliability at any point in usage.

Fault trees can also be used from the perspective of Root Cause Analysis (RCA). This usually occurs when we have observed a failure (or undesirable event) and want to ‘collectively brainstorm’ a series of explanations as to why it occurred. Fault trees used in this way can be used to identify likely ‘root causes’ that can either be the subject of further investigation or be designed out of the system. Fault trees used in this context support ‘reliability improvement’ more than ‘reliability measurement.’ 

Fault trees in this way can be used in a fundamentally more valuable context where we focus on preventing problems like failure before they occur. Fault trees used in this way are often parts of larger proactive reliability engineering activities like Failure Mode and Effects Analyses (FMEAs). If failure is defined as any event where we fail to meet our customer or user expectations, fault trees can help us do robust, customer-centric design. This is where we prioritize what features matter the most to our customers, and we incorporate really simple design changes very early in the production lifecycle to become or remain an industry leader.

Students who design, manufacture or need to otherwise manage any sort of product or equipment will benefit from this course. FTA can be used for modelling TTF and informing key business plan decisions. FTA can be used to identify root causes of failure – both in the past and in the future. This means that FTA can be used to prevent problems, including issues that may introduce production costs and delays. FTA can be used to identify the VITAL FEW problems and issues our product, systems or services need to focus on.

These modules are based on an example that is iteratively developed throughout the course, with students completed exercises and questions in the workbook.

There is a total of 

4 hours of lessons.

This course will be delivered through

Self-paced video lessons.

So, regardless of where you find yourself in life, you 
will be able to do this course when it suits you.

Here is what you get. You get

1-year access

There will always be new developments in reliability engineering, and we will keep finding better ways to tell the story. 
So, as we make module updates, you will continue to get access to the course for one year from the date of purchase.

Then there is

 Ongoing expert Q&A.

I will be available to answer your questions for 12 months after completion of the course. See the course Materials tab to find contact options.

Who is your teacher? Dr. Chris Jackson

Dr Jackson holds a Ph.D. and MSc in Reliability Engineering from the University of Maryland’s Center of Risk and Reliability. He also holds a BE in Mechanical Engineering, a Masters of Military Science from the Australian National University (ANU) and has substantial experience in the field of leadership, management, risk, reliability and maintainability. He is a Certified Reliability Engineer (CRE) through the American Society of Quality (ASQ) and a Chartered Professional Engineer (CPEng) through Engineers Australia.

Dr Jackson is an Accendo Reliability Thought Leader. Was the inaugural director of the University of California, Los Angeles (UCLA’s) Center of Reliability and Resilience Engineering and the founder of its Center for the Safety and Reliability of Autonomous Systems (SARAS). He has had an extensive career as a Senior Reliability Engineer in the Australian Defence Force and is the Director of Acuitas Reliability Pty Ltd.

He has supported many complex and material systems to develop their reliability performance and assisted in providing reliability management frameworks that support business outcomes (that is, making more money). He has been a reliability management consultant to many companies across industries ranging from medical devices to small satellites. He has also led initiatives in complementary fields such as systems engineering and performance-based management frameworks (PBMFs). He is the author of two reliability engineering books, a co-author of another, and several journal articles and conference papers.
