Root Cause Analysis
A Foundation for Effective Reliability Programs
Contributing Authors: Harvey Altstadter, Cliff Lange, Kim Parnell, and Mike Silverman
One of the most important aspects of an organization’s reliability program is the ability to identify and correct failure related issues. Failures can prevent reliability goals from being achieved and increase warranty costs. Often, internal resources are limited in the availability and use of Root Cause Analysis (RCA) tools. Many problems are of a specialized nature, and companies do not understand how to approach these problems.
RCA is a process that is often used for identifying the actual cause of events and then applying corrective and preventative actions to solve problems. A Root Cause can be associated with any of the elements of a product, including its design, manufacturing, and use. This process has significant value in helping to respond to everything from customer complaints, process problems, and accident investigation.
Root cause analysis is not a single, sharply defined methodology; there are many different tools, processes, and philosophies of RCA in existence. Success is achieved by applying the appropriate tool at a specific point in the RCA process.
To more fully assist customers with their respective reliability programs, OPS A La Carte continues to mature the RCA services it provides to the engineering community.
The 7-Step Process Defined:
Many companies employ structured problem solving techniques to assist with their RCA and corrective action activities. The “7-Step Process” (see figure below) is one method frequently used to approach and focus on continuous improvement of existing processes. This process is one that is frequently used today and is summarized below.
1. Define/Identify the problem.
2. Analyze and gather data/evidence.
3. Determine Root Cause: Ask why and identify the causal relationships associated with the defined problem Identify which causes, if removed or changed, will prevent recurrence.
4. Choose solutions and action plan: Identify effective solutions that prevent recurrence, are within your control, meet your goals and objectives and do not cause other problems. The solution should not only address the problem at hand, but also assure that similar problems also do not occur.
5. Implement solution(s) and the recommendations.
6. Evaluate: Observe the recommended solutions to ensure effectiveness.
7. Act/report on what was learned.
(NOTE: some companies call it the 8-Step Process, adding in a last step for celebrating after success).
The process seems simple enough, but companies fail when implementing this process for a few reasons:
a. They work on Step 5 (solution) in parallel with Steps 1-4 (or just as likely, they skip Steps 1-4 altogether). And as a result, they never really understood the problem and either fix the wrong problem, or more likely, only partially fix the problem.
b. Step 5 not only requires that a solution be identified, but that it does not cause other problems. Often times a change in one area may cause a problem in another. A hardware change can cause a software error or vice versa, a change due to a temperature issue can then manifest as a vibration issue, etc. A robust verification and validation process must be defined so that these escapes do not occur.
c. Also in Step 5, the solution tends to be very narrowly focused rather than looking at how to prevent similar problems. If a failure occurred because a component was improperly derated for electrical stress, then a fix may be to change the component to one with a higher rating. A full solution would look at derating guidelines to see if there are changes required to prevent future issues with component derating.
d. Step 7 is rarely done well. Lack of documentation and routine updating of company standards and operating procedures often reduce RCA activity to tribal knowledge. Surprisingly, it is not unusual to see organizations solving the same problems over and over again, only to address the issues with different customers using different engineering personnel. Engineering organizations need to be effective at avoiding errors even when an entire design team moves on to other projects.
e. Steps 6 and 7 often lack reliability metrics. Without the correct metrics in place, it is difficult to measure the effectiveness of corrective actions. Properly selected metrics provide the feedback necessary to assure that the right actions are taken to address the issues at hand. Furthermore, they provide evidence to management that engineering’s actions are having a positive impact to the organizations profitability, customer satisfaction and overall engineering effectiveness.
f. Perhaps the most challenging portions of this 7 Step Process are Steps 3 and 4. Many companies attempt to identify the casual relationships and key contributors to failure using a limited tool set available within their engineering organizations. Here, companies need to really understand what happened and why, and for this, they often need to employ more advanced failure analysis tools and techniques. This usually falls outside their comfort zone or knowledge level. Techniques such as material analysis, finite element analysis, design of experiments, dynamic load analysis, thermal analysis, computational fluid dynamics (CFD), and probabilistic evaluations play a key role in RCA and are generally not part of a company’s engineering capabilities. It is not enough to know about the tools; but also to understand when it is appropriate to use a specific tool and how to apply the tool.
Over the past few years, OPS A La Carte has been maturing both the disciplines and the expertise that makes use of them. Our system approach focuses on:
Implementation of multi-disciplinary approaches capable of solving a broad range of problems quickly and effectively, saving both time and money;
Partnering with over 50 other specialized firms to continue expanding RCA expertise;
Identifying, testing and verifying potential design changes;
Unbiased, independent RCA services capable of satisfying all end-customer inquiries;
Identification of the appropriate reliability metrics to measure the resulting improvements to product reliability.
Our expertise extends to both the system and component level for a wide variety of different areas including electrical, mechanical, materials, chemical, optical, and software. We tap into our vast experience in each of these areas to solve problems quicker and more effectively.
RCA is the foundation for every effective reliability program and is most often the most challenging discipline, because of the many factors involved —design, testing, manufacturing, and installation; including customer usage and environmental effects. It is an essential function of the continuous improvement process and the difference between merely repairing pattern failures and truly eliminating the underlying problems. Only by eliminating the underlying problems can organizations experience improvements in reliability. By putting in place reliability metrics, we can monitor the effectiveness of a RCA program.
OPS A La Carte’s business model of end-to-end integrated reliability solutions is a perfect fit because as the issues become more complex, the only way to solve them is to take an end-to-end, multi-disciplinary approach.

Solution to Last Quarter's Problem of the Month on Prognostics:
PRODUCTION LINE YIELD
A plastics plant operates 8 extruders producing plastic film. Production volume requirements cannot be met if less than 6 extruders are operating. There is a 0.30 probability that a machine stopping malfunction will occur. What is the probability that 6 extruders can remain operating throughout the day?
SOLUTION: We will use the binomial distribution as follows:
where: p(x,n,p) is the probability of exactly x or fewer successes in n trials with a probability of success equial to p on each trial.
Using the binomial distribution, we can expand the equation as follows:
This is the probability that 6 extruders will NOT remain operating throughout the day. The probability of success is 1 – 0.5518 = 0.4482
COMMENTARY: Note that we could have found the answer more quickly by using a binomial table because the binomial table is set up to find “x or fewer” events.
Also note that we could have used the Poisson distribution. The Poisson distribution can be used to approximate the binomial distribution when p is small (generally, less than 0.1) and n is large (generally, n >15) by using np as the mean of the Poisson distribution.
CONGRATULATIONS: Congratulations to Charles Meyerson who was the first to answer this question correctly. Charles chose as his prize a free pass to our annual Reliabilty Symposium this past April.
