- SOR 508 Why DFR is EssentialSOR 508 Why DFR is EssentialAbstract
Carl discusses why Design for Reliability is so essential to attaining high reliability.
Key PointsJoin Carl as he discusses the following topics:
- Early applications of reliability focused more on reliability testing, reliability statistics and reliability growth than reliability in design
- Reliability needs to balance three factors: fast to market, meeting budget constraints, as well as achieving high reliability
- It is difficult to focus on DfR and fixing problems at the same time in one’s job
- Co-location of reliability engineers with design engineers can facilitate DfR
- Learn and apply the different mechanisms of failure

Adam discusses why the reliability engineer discipline is unique in that it encourages the “Celebration of Failures”
Key PointsJoin Adam as he discusses why the reliability engineer discipline is unique in that it encourages the “Celebration of Failures”
Topics include:- A reliability engineer knows that product failures occur weather you see them in test or not.
- If they can be observed in product development then they can be addressed before product release. if no tit is up to the customer to find them, which both teams and customers don’t like.
- Educating design teams to celebrate failures and value them as critical design input is a critical part of the reliability mindset.

Kirk discusses his experiences in semiconductor manufacturing and systems manufacturing that led him to an understanding and agreement of the radical ideas that Gregg Hobbs was proposing with HALT and HASS methods.
Key PointsJoin Kirk as he discusses his experience and long working experience with Gregg Hobbs, PhD. , who originated the methods of HALT and HASS through testing to empirical limits and using those limits to apply to find weaknesses that will cause failures in time.
Topics include:- The significant intrinsic strength in electronics materials
- Most product failures are due to misuse or error in design or manufacturing and not intrinsic wear out mechanisms, especially in the first several months or years of use.
- The only way to improve the reliability of a product is to understand why it is unreliable in the field.

0 min - SOR 503 Profit Today Versus ProfitabilitySOR 503 Profit Today Versus ProfitabilityAbstract
Chris talks about what ‘profitability’ is … and it is not ‘profit today.’ Why is this distinction important? Because focusing on profitability takes care of all of your future ‘profits today.’ But it does not work the other way around. There are plenty of contemporary examples about how we can get this wrong – think Boeing and the ‘mess’ it is currently in. Want to learn more? Please listen here!
Key PointsJoin Chris as he discusses ‘profitability’ versus ‘profit today.’ Chris talks about the issues Boeing is facing today as a result of the catastrophic crashes of its 737 Max 8 aircraft. Aircraft that as of today cannot fly – even though airlines across the world have paid a lot of money for lots of them. Boeing can’t tell us when they will be back in the air because they don’t know what is wrong with these aircraft – aircraft that were once ‘certified as safe.’ So Boeing is in a state of turmoil right now. And it is all because it focused on ‘profit today.’
Topics include:
- Boeing phase 1 – 2013 to 2018. The then CEO was very popular with his shareholders and the board of directors. Boeing was making lots of money. But he was making his suppliers, relevant regulators, foreign governments and competitors unhappy (in a particularly negative way). Boeing’s ‘Partnering for Success’ imposed arbitrary cost reductions on suppliers. He tried to limit a competitor (Bombardier) from competing with Boeing in the market place. Problem was that the Trade Commission didn’t support Boeing’s claims. And so we have a somewhat unscrupulous approach to driving down costs and using mechanisms besides ‘just making better aircraft’ to increase market share. And this affects organizational culture.
- Boeing phase 2 – 2018 to now. Two of Boeing 737 Max aircraft crashed, killing hundreds of people. Both were (at least) partly caused by an ‘MCAS’ system malfunctioning, overriding the pilot controls with the onboard computer thinking that the aircraft was sharply diving when it was in fact not. And there is now a lot of evidence to suggest that Boeing rushed to get aircraft certified – perhaps jeopardizing ‘good’ engineering practices. And the CEO responded by (1) calling the US president and not the head of the Federal Aviation Administration or FAA (2) repeatedly setting and failing to meet deadlines for FAA certification of the proposed fix to the MCAS system – which as of now still hasn’t been resolved. It should be worth noting that the FAA controls its recertification schedule – not Boeing.
- Big picture? Airlines have lost confidence in Boeing’s ability to understand the problem – let alone fix the MCAS. No one knows what it will take to have these aircraft in the air. So airlines have ‘nothing’ for the money they paid.
- So what. Phase 2 is a product of Phase 1. Increasing ‘profit today’ is most easily done by not spending on the future. The second easiest way of increasing ‘profit today’ is changing the rules. Rushing through certification when a system has no right to be certified. Trying to bar competitors from your marketplace. Both are alluring options. Easy. Gouging money with no immediate effect. Trying to make rules apply to everyone else and not you. But the effect will come.
- It’s worse than simply ‘gouging money.’ Because those alluring options for maximizing profit today take you away from your core business. Designing safe aircraft. Manufacturing reliable consumer products. Making something that customers like. And so on. And this is the key to profitability.

Carl discusses why focusing on the vital few reliability methods is key to successful reliability programs.
Key PointsJoin Carl as he discusses the following topics:
- A reliability plans is not a long list of reliability methods
- Use a reliability gap assessment to narrow down the vital few methods
- Prioritize and focus your work (Pareto Principle)

Adam discusses how data can be used from existing databases and specially designed tests to characterise products reliability performance.
Key PointsJoin Adam as he discusses discusses how data can be used from existing databases and specially designed tests to characterise products reliability performance.
Topics include:- The modern approach to reliability data generation and analysis is greatly different then a few decades ago
- Engineers should encourage programs to invest in testing that generates specifically designed data.
- Approach large established databases with suspicion. Technology moves fast and many have not been kept up with the times in theory or content.

Carl and Fred discussing the shortcomings of the use of RPN in an FMEA, and what specifically can be done to prioritize risk in an FMEA.
Key PointsJoin Carl and Fred as they discuss a better way to integrate the three types of risk in an FMEA, in order to prioritize risk for corrective actions.
Topics include:
- What is RPN?
- What is wrong with RPN?
- What alternatives are their to using RPN?
- Always address high severity first
- Severity can sometimes be reduced by design change
- How to address high severity, low occurrence issues
- FMEA action strategies to reduce risk
- Use of risk matrices in FMEA
- Use of action priority table in FMEA
- Caution when using FMEA to predict reliability
- FMEA scales are meant to prioritize risk, and are not intended to represent objective values
- One of the most important aspects of FMEA is the team discussion
