Speaking Of Reliability: Friends Discussing Reliability Engineering Topics | Warranty | Plant Maintenance

Future Reliability Engineering Abstract Mojan and Fred discuss the monumental reliability challenges of a mission to Mars. While the fundamental physics remains the same, they explore why success depends on a more rigorous application of existing methods, autonomous systems, and the shift toward heavy simulation and in-situ repairs. Key Points Join Mojan and Fred as they […]

Best Recommended Option Abstract Chris and Fred discuss which liner is best to use on a centrifugal pump, or make a general recommendation. How do you make a recommendation using reliability performance? Key Points Join Chris and Fred as they respond to a listener who asked how to identify the best liner for a centrifugal […]

Analyzing failure data for repairable systems sounds straightforward—until you start asking the right questions. In this episode, Chris and Fred unpack a listener’s challenge: how to model reliability when failed components are repaired and returned to service. The discussion quickly moves beyond Weibull curves and into a more uncomfortable reality—maintenance itself often increases failure risk, at least in the short term. With limited data and multiple failure mechanisms at play, traditional statistical approaches can mislead more than they help. Instead, the focus shifts to understanding failure physics, questioning assumptions, and making practical decisions that actually improve reliability—not just model it.

Modeling Maintenance Benefits Abstract Mojan and Fred discuss how to integrate service plans into reliability target planning. They explore the shift from “worst-case” maintenance schedules to data-driven strategies, highlighting how predictable failure mechanisms and telemetry allow teams to take credit for high availability in their reliability models. Key Points Join Mojan and Fred as they discuss the […]

Why Paper Jams Persist Abstract Mojan and Fred dive into the surprisingly complex world of the “paper jam,” a problem that remains a daily frustration despite decades of high-level scientific research. From Fred’s time at HP to the massive technical laboratories at Xerox, they explore why the interaction between rigid mechanisms and non-rigid, organic media […]

Risk Prioritization in FMEA Abstract Carl and Fred discuss a question from a reader about risk prioritization in FMEA procedure. Key Points Join Carl and Fred as they discuss the role of risk prioritization in FMEA, what is it, and what is the best way to prioritize risk in FMEA. Topics include: Discussion of history […]

Our Unique Role in Reliability Abstract Carl and Fred discuss the ongoing challenge between doing reliability work ourselves and enabling others to accomplish the work. And what is the future human role in the field of reliability, given the advancements in AI? Key Points Join Carl and Fred as they discuss the unique role of […]

Data Gathering Challenges Abstract Enrico and Fred discuss discuss the challenges of data collection in reliability engineering, prompted by a listener working in asset reliability. They explore why gathering useful data is often the most difficult step, how modern connected systems are changing data availability, and why defining the purpose of analysis is essential before […]

2 HALT Objections Abstract Kirk and Fred discuss the value of HALT for a product late in a new product development process. Key Points Join Kirk and Fred as they discuss whether applying HALT yields a good ROI (return on investment) when they are already working on reliability problems discovered during standard development. Topics include: […]

Clarifying a Point About HALT Abstract Kirk and Fred discuss the continued meaning of the acronym HALT, which was originally coined by Gregg Hobbs, Ph.D., P.E., to stand for Highly Accelerated Life Test, which is a misnomer. Key Points Join Kirk and Fred as they discuss a listener’s question about the use of the term […]
