Download Audio RSS Show Notes Reliability engineers and quality engineers often find themselves needing to facilitate a meeting. Root cause analysis, continuous improvement, and other scenarios require teamwork. A challenge can be playing the facilitator role while you also want to be a contributor. These roles can be at odds with one another. Facilitators guard the process and ensure everyone is heard. Contributors have ideas and opinions to share with the team that help define the solution. When you must facilitate, there are ways to shift from one role to another. Fred and Dianna talk about several ways to make the shift. Facilitating itself is difficult and requires skill. Some suggestions they have: Plan ahead Define the scope well Know how decisions will be made Follow up with actions One of the biggest takeaways: make it visible to everyone. Quality tools are examples of models and templates that that work. Whether you facilitate in-person or are using remote tools, be sure you understand how to use the tools. Don’t let your misunderstanding about how to use tools create disruptive pauses in the process. In conclusion, be cautious about the roles you play, and make it clear to the team which role you’re playing when. And you can enhance your career if you practice your facilitator skills. Do you have any success stories to share? The post SOR 1021 Influence vs Facilitation appeared first on Accendo Reliability.

Can Manufacturing Improve the Design Abstract Chris and Fred discuss how reliability and quality is destroyed by organizations that like to have a ‘razor’ split between design and manufacturing teams. Why? Key Points Join Chris and Fred as they discuss when organizations see design and manufacturing functions as distinct, separate, never to talk to each other, and completely unaware of the other (this is a bad thing by the way …) Topics include: Around 80 % of quality problems start with design. That’s right. Most of those ‘manufacturing’ defects come about when the design teams come up with ideas that can work … but simply can’t be built with the machines in your manufacturing facility. Whether this is being metal at crazy angles, tolerances that need to be within one-millionth of one-millionth of one inch otherwise it catches fire, heat sensitive material that is next to welds and so on. Manufacturing teams can only make designs ‘worse.’ Of the 20 % of defects that aren’t rooted in crazy designs, the only thing that happens is that quality and reliability is reduced from what the design team were hoping. But all the (other team) does is tell us what they can’t do. That usually means they are responding to your crazy design/manufacturing process which assumes the other team can accommodate it. Instead … the teams need to speak to each other before they design and build to know what the other CAN do. And then work accordingly, so you have no conversations where they have to tell you what they CAN’T do. Do you have a team that re-designs things to make them manufacturable? Then we are talking about you. Designers are not special geniuses that need no boundaries so they can innovate. They need to be real world people. Enjoy an episode of Speaking of Reliability.

Calculate Equipment Reliability Abstract Chris and Fred discuss how we can go about calculating equipment reliability … when you only have a small amount of information. Help! Key Points Join Chris and Fred as they discuss how you can calculate equipment reliability when you have a little bit of information. This comes from a listener who asked us to calculate the reliability of their equipment that failed four times in one month (with 400 hours of operation).  How do we find this system’s reliability? Topics include: So what is the number? If we assume a constant hazard rate (yuck) then we can use the exponential distribution to work out that the reliability at one month (400 hours) is 1.8 %. Is this helpful? Our listener didn’t tell us why they wanted a reliability number … but 1.8 % is almost certainly useless in terms of making better decisions. Why? Well we don’t know if our equipment is wearing in or wearing out. We don’t know if we have 10 pieces of equipment working at the same time over this month, with only 4 of them failing. So what do we do? What is the DECISION? This is a common question (refrain). What are you deciding to do with this number? We can’t think of a single decision that this 1.8 % estimate will help. Again, we don’t know if the equipment is wearing in or wearing out … which would affect our estimate. Knowing the precise times of failure would be really helpful as well. But is the decision more useful if it is based on availability? It sounds like the equipment is being repaired, so how long does it spend being repaired? What is the DECISION! Don’t just stick with numbers … look for WHY? Are you doing root cause analysis (RCA)? If you can (for example) quickly identify that the four failures were caused by incorrect startup procedures, and a quick change to those procedures would make the problems go away … fix it! Stop doing statistics on numbers you can make go away. Enjoy an episode of Speaking of Reliability. Where you can join friends as they discuss reliability topics.

Do it Right the First Time Abstract Kirk and Fred discuss the risks to reliability of having to rework or human handling of circuit boards and rework in general. Key Points Join Kirk and Fred as they discuss process control and hand soldering and how it increases the reliability risk compared to the original production line produced circuit boards Topics include: Reworked solder joints are inconsistent and human touch-up carries a greater risk of failure than the original re-flow oven soldering. Rework and repair are often referred to as the hidden factory as the costs of touch-ups and failures of the rework are not always financially accounted for. A fundamental tenet of reliability engineering is that if you do not know the physics of why a system fails and why it's unreliable, you will not know how to make it reliable Customers, in general, expect more reliable products, and the smartphone industry has made them more shock-resistant and water-resistant in each new iteration of the design.

Kirk and Fred dive into how moisture, particularly from saltwater, accelerates failures in various materials. They discuss the surprising leakage rates of O-rings and the hidden dangers of moisture in electronic encapsulations, leading to eventual failures. The impact of hail on solar panels is highlighted, along with the harsh realities of flooding on vehicles designed to resist rain. In dry climates, humidity becomes a double-edged sword, increasing risks for electronics. The conversation emphasizes the critical need for robust testing to understand and mitigate moisture-related issues.

Two Approaches Abstract Chris and Fred use the safe return of the Boeing Starliner … without the crew! What does this tell us about its safety and reliability? Key Points Join Chris and Fred as they discuss the recent incident involving the Boeing Starliner crew module that managed to get a crew to the International Space Station (ISS) but was not deemed safe enough to return them. But it has since ‘safely’ landed. So was it safe? Is it safe? What about reliability? Topics include: Russian roulette is ‘safe.’ If by safe that means that there are outcomes with no undesirable outcomes. Russian roulette (depending on who you ask) involves a single bullet being placed in the cylinder of a revolver (gun). The cylinder can hold six bullets. The cylinder is then spun so that there is a one in six chance that a bullet will be fired when the trigger is pulled. So there is a five in six chance that no bullet will be fire when you pull the trigger. So does this mean that Russian roulette is safe five times out of six and unsafe the other time? NO! It is always unsafe because it is all about the PROBABILITY of something bad happening. Is Boeing ‘safe’? No. NASA’s Inspector General has been very critical of Boeing’s ability to safely, efficiently and effectively develop spacecraft. Issues include not having enough people, not having enough of these people appropriately trained, not responding to corrective action requests from NASA and LOTS of others. Why? Well, while Boeing does have a history of space exploration dating back to the Apollo program, that history is dated. And no longer relevant. So Boeing won contracts from NASA to build spacecraft and THEN tried to create a team to build it. Compare that with SpaceX, which is much younger, but was established with the unambiguous goal of creating all manner of spacecraft before NASA came along offering contracts. So SpaceX built it’s own workforce, worked out its own development processes, put its own skin in the game by building its own spacecraft before signing contracts from customers like NASA, tested to learn and not testing to pass and so on. So this is why SpaceX spacecraft will now return Boeing’s stranded crew back to Earth. Organizations hunting for money are destroyed by organizations that have found their purpose. General Motors famously developed an electric vehicle ages ago, until it was killed off because it wasn’t making money straight away. If General Motors was able to go back in time … it would almost certainly reconsider! If they had maintained their electric vehicle program they would potentially be a market leader today (which they are not … they are just a ‘player’) noting that groups of countries are starting to only allow electric vehicles on the road. So what do you do? Does your organization only judge success based on immediate returns? Meaning that everyone is hunting profits by week? This means there is no long-term vision which means you meander your way to obsolescence. It is those companies that stick with their long-term vision through highs and lows. Amazon took decades to create a meaningful profit … but it is kind of a big deal now! Enjoy an episode of Speaking of Reliability. Where you can join friends as they discuss reliability topics.

The Trouble with Habits Abstract Chris and Fred discuss the issues we often have with ‘habits.’ Habits can be good for us. But ‘bad habits’ are just that. Ever heard the excuse ‘but that’s the way we have always done it?’ Key Points Join Chris and Fred as they discuss how ‘habits’ dominate our lives … both for better for worse. So what does this mean? Topics include: Decisions are about CONFIDENCE.  You can be ‘confident’ to make the right decision because you fundamentally know and understand all aspects of a problem, and know what will remedy it. Another form of ‘confidence’ occurs when you look for standards or procedures to comply with … which usually only happens when you don’t know and understand all aspects of a problem. You can get ‘confidence’ from having what appears to be a water-tight legal contract. You can also get ‘confidence’ from simply doing what has always been done. So not all CONFIDENCE is equal. And it comes down to culture. If you are a leader, and want to look for someone to blame when something goes wrong, then you are creating an organization that is based on ‘confidence’ from doing what has always been done. So no one risks anything. Nothing changes. You slowly drift toward mediocrity, and then to irrelevance. The best form of CONFIDENCE is the stuff you get from KNOWLEDGE. Which again comes down to leadership. If people make the right decision based on seeking information on hand and using it, AND you reward that decision even if the outcome is not optimal or desirable … great! This means you become an organization that fails fast, and fails your way to the top. You are actively pushing the boundaries of your organization’s knowledge by having this mindset. And this is what you tend to see in true industry leaders. So what organization is yours? But don’t get LAZY. If you used Highly Accelerated Life Testing (HALT) for a component last year to great effect … that doesn’t mean that this is the right thing for all components moving forward.
