Six Sigma | ZERO Defects 1: You don't want this | Green Belt 2.0® Lean Six Sigma | fkiQuality HD

[@KatieBrown-i5q]

Very detailed explanation of zero defects and how it is the first step of quality to lowering cost and risk. Specs are derived from listening to the customers concerns to achieve balance and satisfaction.

[@DannyG-d2f]

It's clear that hitting a target with minimal variation is the modern standard for high quality. We need to be able to determine the trend of results so that we can anticipate future results with better accuracy.

[@GregBoal-o2m]

its an interesting way to look at it as trying to hit a target as often as possible instead of just being in a range

[@Music1234Man]

This is really changes my perception about how to view quality. And it makes so much sense when you try to hit a target goal with minimal variation versus being in/out of specifications. I think the biggest component of added value is the data that you can feed back to improve, and running your operation more efficiently knowing you can repeatedly hit deadlines.

[@victoralvarado943]

I like this, a lot to learn on this video for zero defects.

[@christianhagner6509]

I absolutely love the visual representation of the coffee model. It's relatable and pushes through the concept of zero-defects. It's easy to miss the fact that a process is gradually widening it's tolerance rather than tightening it. I think that's how you get companies that excel with their product so 'easily' while others flounder wondering what they're doing wrong. And so many companies don't listen to their customer base, when this should be of utmost importance to them because if they can tweak their process to meet their customer's needs, it would save them money, time and other resources, AND would make a much happier customer base.

[@djenansoumahoro5797]

Redefining zero defect as continuously eliminating the variation from the target value. For our operations, a machining target value would be the nominal dimension for each feature being produced. We often find that a lot of our defects could be avoided if we could consistently meet that target value.

[@tedkozelka203]

This video really captures the essence of a problematic theme in many companies; everything is fine while there are zero defects, but when something goes wrong, everyone loses their minds! The coffee example accurately captures the loss of perspective about trends in data. Good video, these lessons can be applied nearly everywhere.

[@KyleNwogu]

This helped to open me to a new perspective on quality, from what I have learned in the past from previous experiences at my last job, everything was based on making sure we have zero defects.

[@ChrisLenart-e9u]

I appreciate this topic. i had not realized that data would/could be manipulated (by opening open tolerances) to reflect 0 defects. This hides that there is too much variance until people become complacent enough that the data eventually outgrows the opened tolerances as well. This video highlights the importance of setting a target, not a range.

[@brigittedickey661]

There is always room to make what you are working on better- to improve. I like how you used something a simple as coffee to demonstrate this as it makes it easier to understand. Keep improving to get to a zero defect.

[@Bittersweetdstny]

This is a great example of perfection not necessarily being possible or can be too time consuming and costly to be achieved. Widening the parameters of success makes the gauge too large and will ultimately lead to unsatisfactory results. Thanks for uploading.

[@danagreene6800]

Good knowledge on how defects are measured. Watching the coffee demonstration again really helps to get familiar with the standards.

[@jasonholesha3148]

Interesting way to look at things when you are looking at the limits and what is good and isn't and how if we look at it at from the limits side things can become binary. By looking at quality with definitive means, it doesn't allow for complacency when things are good.

[@hillary6019]

I really liked the point about not just focusing on Zero Defects. We can also aim for an optimal target in order to continually improve. Too often we do focus on not doing something wrong instead of focusing on improving something we've already done right.

[@christopherinc3980]

A great way to get started and understand how a different perspective can create a better experience for the customer.

[@AndyPostula]

Watching the coffee demonstration helps to get familiar with adding in new values during the valuation process to better achieve minimal / zero defects.

[@keithallen2331]

I would have never thought that looking at quality as good or bad would ignore the fact that things tend to get worse overtime. To go beyond zero defects by setting a target and continually aiming for it with minimal variation is something we all should adapt.

[@alanharker2433]

I like how you explain how Lean Six Sigma drives you to produce a more consistent outcome by setting specific goals instead of being content with completing within the range.

[@ryananderson8130]

The connection between customer and defects is much greater than I originally thought. To be in tune with customer voice and expectation is critical, especially in an ever changing customer culture and opinion. I think the key is company research and customer feedback programs. If we can't measure our customer expectations we will not have the accurate scope of what is defective and what is quality.

[@DavidRoberg]

This made me think of my role working with rental tuxedos. The phrase "they have to remember it's just a rental suit" was thrown around a lot in the DC, but the customers never cared - they still wanted high quality for what they were paying. I don't think it's a coincidence that we used that phrase as our operation got tighter over the years.

[@joellenmcintyre4821]

This explanation of better understanding why it is important to try to hit the target and to better understand that the trend is very important.

[@bradhentz7102]

This is a great, simplified explanation of what lean and six sigma is as well as what it looks like. Without specific targets, focus and innovation can be lost and the work, due to the nature of ranges (upper and lower limits), becomes about being "acceptable" or "good enough". It doesn't drive towards excellence. In my professional experience, aiming for "good enough" is about tweaking increasingly obsolete processes to stay within limits while targets create new processes through innovation and creativity.

[@christopherrogers7303]

Good input, Mitch. I remember in the movie "Robin Hood", Kevin Locklsey said "aim small, miss small". This video reminds me of that. There is value in setting a range initially (I would imagine) considering their are milestones as you begin to improve, but a set target helps us identify additional special causes that may not be identified with a wide range.

[@Money_Co]

I love how there is always room for improvement and having a number is a great way of doing this.

[@mmaphefoseseni6625]

This forces one to always think of better ways to work, with concepts like this, your brain is involuntarily forced to operate beyond average, which results in your mind constantly digging for better ideas. it is like food for the brain. Definitely headed to part 2 of the video.

[@rickk3487]

take-aways... Lean = zero waste; 6-Sigma = zero defects ... aiming for middle of spec creates consistency, less chance to wobble into NC territory which leads to fewer defects, and thus improves the bottom line when it comes to zero waste.

[@joshturnbull1850]

I fall victim of the "well it is in spec" mindset from time to time. This does a great job showing you how taking the step to operating to the target can help control variation and have a lasting positive impact

[@nicholaspesek5902]

This is a very interesting concept not just working to be within an acceptable range where you have some variation but really striving for the perfect target and calculating it by number on target instead of zero defects.

[@CharlesStone-s3i]

I like the phrase of looking at quality as “good or bad” ignores trends! I hear the phrase as in is in a lot and we don’t look past that! But we can actually look into it to what can make this more consistent each time we see this problem!

[@ronaldtucci6091]

So many companies and people view quality as a measure of good or bad but fail to include the variations. Decreasing the variation will equal superior results. This way the focus on the correct target and includes the right changes.

[@ethanmarbery5974]

I see this a lot in sales adds on zero defects and it makes sense that if there is a broad range of tolerance the less defects you have but if you include the target value all the defect numbers look much higher.

[@lesliebdelgado9666]

Interesting to realize how setting correct parameters/goals is so relevant. Also, I enjoyed realizing that quality should not be good or bad but something to be improved on the long run!

[@jeffreysundwall7812]

I agree that certain goals should be set. In machining, we need to aim for the print dimension, we are given an acceptable tolerance (high/low, max/min) but if we machine always on the edges of the tolerance, we can experience rejects.

[@tiamiller6470]

The coffee example was helpful in illustrating how maintaining zero defects was not enough but should look at continuous improvements to help minimize variation

[@Ganjagoddessgrower]

This video made it clear that instead of setting a range, choose a target. This will lead to fewer defects. This improves quality too, improving on the front end processes in stead of fixing problems at the end.

[@johnstanley491]

This shows you that quality doesn't end with meeting expectations. Exceeding expectations sets you up for success in the future when the competition gets tougher.

[@Jaguzma2]

The definition of specs was a pretty good definition. This takes into account customer satisfaction, the cost and the complexity. Perfection does not matter if customer satisfaction is not met, or if it is too costly to keep these standards.

[@jennifersacksteder9846]

This reminds me of customer specifications, where we have a range that the spec can be in but we should focus more on hitting the middle of the spec to avoid material being out of specification to increase the on target rate

[@donnalevy8455]

Good analogy. There will always be variation but reducing the variation is key.

[@jenniferb5322]

I really enjoyed this video! The continual pursuit of perfection, improvements and setting a target seems similar to a concept I like to use in my professional and personal life (strive to be proactive with thoughtful improvements versus reactive to bad results).

[@insertwords10791]

Usually the challenge isn't in hitting a certain number or target, but doing so consistently. Everyone will be different, but starting off with reliable expectations that can consistently be met usually helps grow trust between companies. Anyone can promise fast, but proving consistency is what separates the good from the great. And once that variation is controlled, it's usually easier to improve upon the average.

[@Joebob-l4m]

One of the key point for me in this video is "stop thinking of quality as good or bad if you want high quality over the long run".

[@renztabiliran8131]

It’s the same concept between Accuracy vs. Precision. It’s really good to be accurate and precise all the time but cost, manpower, equipment and other factors should be evaluated as well. Thanks for sharing this video Francisco.

[@aaroncrenshaw6540]

Driving to Zero Defects was setting up barriers and moving to a set target. This is a very good way to get to Zero Defects with a group.

[@sherisezynel5048]

Thank you for showing that just because the product doesn't have any defects, you can't just look at it as defect free, but what is the improvement? The benefits? Concentrating only on the defects prevents you from concentrating on what's right.

[@CjRodriguez-nn3vk]

I like the thinking of being on target rather than just having zero defects. It is less costly and risky.

[@margaritorios]

Just like in the Ford Transmission Quality Study video. Great analogy using coffee, very clear!

[@mitchellhoem2003]

I think it is important to understand that in certain businesses customer preferences can change. In the coffee example, what would your on-target number look like if customers' preferences changed to reflect and optimal temperature of 140F? It is important to continually get feedback from your customer base in order to keep your target aligned to the customer.

[@adammademann4414]

Compelling argument/notion about aiming for an actual target, with minimal variation, when seeking to improve a process. Much more effective than have a simple binary outcome of acceptable vs not acceptable. I also appreciated the clarification at the beginning of this presentation (although this should be well drilled by now) that Lean seeks to achieve "zero" waste while Six Sigma seeks to achieve "zero" defects.

[@fkiQuality]

Adam, the statement of what each Lean and Six Sigma seek to achieve is meant to clarify their main focus and approach, but it is not a limiting statement. That is, Toyota (Lean) also seeks to reduce variation to produce perfect product, and it also applies statistical process control with great results. Recall an earlier motto of the Lexus brand: "the relentless pursuit of perfection."

[@adammademann4414]

@@fkiQuality Understood. Thanks for the follow up and clarification Francisco!

[@johnt7374]

Consistent to a target, not a range, reinforced the reason to focus on the process, not just the product or result.

[@ryanperlic4567]

It reminds me of "Goal Zero" Safety, you always want to prevent safety incidents, and you must always strive to remove any unsafe actions, not just change definitions to adjust safety.

[@1999Ashay]

In the coffee example, to get all the data points into tolerance, the boundaries was extended. This is a great example of manipulating data and selling customers wrong information. When it comes to quality it is important to be precise and consistent with your data

[@EricTheConversation]

A majority of the time, companies are making product per what the customer wants rather than what manufacturing can hold. It is easier to have the conversation about increasing the tolerance up front rather than 20 years down the road. It will be a win win for both parties.

[@kennethmckillip3983]

It is surprising how many people and companies still have the initial view of "0 Defects". They just get there and say, yeah, we're good! I agree with the video in that looking for the target with minimal variation is a much better way to go.

[@mitchellalberts9231]

I appreciate the insight to focus on the issues surrounding linearity. How else would we know what is approaching out of spec unless we have a benchmark between our spec limits? Great insight.

[@jorgecifuentes7283]

Great experiment overall and can see how this is a great way to teach lessons on how not to run a business. I would like to believe that this has been well received by previous management teams, as it brings to light the potential obstacles to a continuous improvement environment by not allowing the creativity of the employees to find better ways to achieve a different outcome.

[@shannonvanpatten8774]

I like the idea of looking at the percentage of on target as a new wy of looking at the quality of a product. Less variation is what should be the aim.

[@jorgelgallardo]

It is a great concept to grasp. It makes the organization customer focused and highly competitive in the market

[@domingomoccia2038]

Some manufacturing companies customer's specifications as process control specifications rather than establish in process specification based on specific targets that minimize variability

[@jdpatt904]

Looking at how we run our business only focusing on whether something is good or bad. Total change un mindset great stuff here

[@Student-ws8wg]

QC, QA, and continuously testing for customer satisfaction are essential to the entire quality process.

[@kathyknapp5519]

Good illustration that "zero defects" means within pre-defined specs so drawback is that "zero defects" doesn't control for variability. Controlling and reducing variability is part of important and part of continuous improvement. Better to combine specs with the concept of Target and also measure % of time you actually achieve the Target. Thanks!

[@nikiansell9949]

I thought using an everyday example like coffee was a good way to put it in perspective. My initial thought was why a large range of 20 degrees would even be considered acceptable, so I like that the discussion was later tightened up by defining a target vs. an acceptable level of tolerance.

[@ajvarg1882]

When in "putting out fires" mode, zero defects is defined by the use of the whole range of tolerance versus achieving the nominal.

[@jeremya5241]

This is very relevant to a discussion we just had and it helps to provide a better way of looking at the issue we are trying to resolve. Let's look at how we do it right versus just not doing wrong.

[@fkiQuality]

Good observation, “not doing something wrong” is not the same as doing it right.

[@alejandragarza6402]

Interesting to know there is an actual difference between Lean and 6 sigma with regards to reducing waste and reducing defects

[@GlennFrazee]

This reminds me of the old adage, where some people will do just enough work to NOT get fired. Real quality comes from trying to approach the ideal.

[@xxqqff]

Sometimes design engineers will attach "boiler plate" tolerances to their designs that end up being far too tight for the specific occasion and a discussion about widening the limits has worked and saved lots of time and money.

[@RichardThiel-y5j]

Living by an acceptable range of deviation without constant monitoring can easily lead to going out-of-spec and not having the ability to recover in time. (Similar to driving very close to either stripe defining a traffic lane. Any unexpected obstruction may force us out of our lane and into danger.) Better is to monitor deviation from a target in order to stay close to it. Then unexpected events may not necessarily push us out of the acceptable or safe zone.

[@karimerrills207]

From the video, I learned the process has to be monitored & adjusted in order to have a clear look at whether a company is producing at the expected level. This can be obscured when there is a binary point of view, as indicated in the video when measuring the quality of coffee. If the company only views quality based upon zero defects what happens if there is a new indicator /target, this may expose problems to late.

[@BeatriceDosu]

This video/lecture explains clearly the reason why every business or establishment needs to consistently reexamine their operations even when they are profitable, to find ways of bettering their processes to increase their bottom line by continuously reducing variations.

[@danjezierny1952]

Pointing out the need to strive for better than 0 defects in the long term will help keep new competitors from entering your market

[@jessicafillinger5883]

I like that zero defects is not actually the target. its defining the target and the acceptable range

[@jakehardy7772]

This really makes me think about how people use tolerances at work especially with small quantity develop jobs. It’s easy to make a 50 piece develop “good” or “in tolerance” but when the 100,000 piece order comes down for the same part it’s nothing but problems.

[@nathanfey6835]

The coffee model translates fairly well to my industry (laboratory) where the integrity of client samples are governed by quality control measures. A laboratory control sample (LCS) will have upper and lower control limits that the result must fall between in order for the associated client sample (product) to be reported. If the LCS is out of control, this indicates there is a problem with the system, or process. Depending on the situation, the result will either be qualified and reported or re-analyzed after investigating the root cause of the failure. Re-analysis means reprocessing, which means time-loss. Redoing an entire analytical process has two main negative outcomes - loss of efficiency and in some cases failure to meet a client deadline. We track the number of these types of failures monthly as performance indicators, but we also take preventative actions to search for trends within the control limits. For example, we'll open an Out Of Control investigation if we have five sequential ascending or descending points while still within the upper and lower control limits. I'm looking forward to diving further into this from an operations perspective.

[@Ace_theMaster]

It becomes very crucial to monitor variation and defects when you get to the food industry or other industries that depend on human consumption and human use on themselves. This very big and important reason is "recalls". If you do not set up a good monitoring and inspection system in your processes, you can mess up the "recipe" of your product by not adding the proper amount of components or having foreign objects get in to the mix. Recalls are extremely costly for the company, which could lead to an enormous amount of waste of product, which comes from recalling it, the investigation that needs to happen to find where specifically the deviation happened, and any possible lawsuits that could spring up after the fact.

[@julianmcdonough1590]

Agree with having a target instead of a range and having a margin of error or accuracy goal instead of pursuing perfection and losing sight of other things along the way.

[@jeffmaes5892]

It is important to set a specific goal and strive to hit it, and not just aim for a good / zero defect range. There is always room for improvement.

[@collinschmidt915]

In the chemical processing industry this could mean less product re-work, decreased blending, and less work for production planning after product is already made

[@alexissmoot6291]

I agree that looking at quality as a good or bad bucket is not the proper way to reduced variation which this video shows.

[@troytrapino6249]

great video I just wonder how you approach pas fail requirements?

[@Samrwil-g6q]

This video makes me think twice about defects and what is considered "99.99% effective" because if you keep moving the target, your results can say anything you want them to.

[@stacieevans139]

the main idea is how good is good enough? is it meeting the specs or is it having less than x number of customer complaints in a given month. in reality you want to continuously improve your process to provide the best quality with reasonable cost.

[@yunielcarmona3377]

Alot of great info, learned a great deal

[@rebekkaherrington4509]

The idea of moving the goal posts when trying to operate within a range really hit home. There's specific example at work where a process improvement team did something like this and then considered the project a success. It was short sighted. They should have set a target rather than redefine what is acceptable.

[@nathanstratton7918]

Before evaluation of process, it is more important to determine a target based on customer feedback

[@oscarchiquito3292]

This concept focuses on maintaining efficiency yet maintaining the best quality possible that is promised to the customer/consumer. I enjoyed Francisco's coffee example as well. Makes me think of the reason why Stella Liebeck sued McDonald's☕ Coffee was too HOT🔥

[@maxinegomez5306]

I think that there is also something else that we should consider. At the right costs... at the right risks... One may also discover that the target or goal is not sustainable and need to be reevaluated and/or the higher costs is worth it if the customer also finds value.

[@Adam-fd6qp]

Creating a target value identifies where the perfect coffee temperature would be. It also starts the conversation on how we can control this temperature in a better way to create a more consistent result for the customer.

[@fkiQuality]

Hi Adam, yes, having a target, something to shoot for, starts a constructive discussion about how to get and stay on target. This is the first step toward sustaining any improvement.

[@joshklinzing4608]

Lean Six Sigma is about continuous improvement towards a goal - not away from a defect. The process, operation, and business will all perform better with this approach to quality.

[@nicholashumphrey8654]

Focusing on a central target instead of having zero defects seems like a great way to achieve precision and predictability. The focus is on control and not just hitting the board anywhere. Does this tie into SPC?

[@fkiQuality]

Yes, this ties into SPC, because SPC lets you to stabilize the process by identifying and systematically eliminating the causes of the special variation until you are left with just random noise. Once you have a stable system, then you can look at ways to make it better by controlling the causes of common variation. We do this with the fishbone and five why’s analysis. But remember that we must first stabilize the process before trying to improve it.

[@kslead27]

Having a spec range will never allow you to continually improve. It only allows you to continue to be OK with variation of your product or service.

[@johnsciortino3851]

Using in my role, it's hard to use. We get a finished product to package. Our ship method falls under this as we give fluff days to assure product get to the customer on time. The theory makes sense but I am still trying to figure out how it could work for me.

[@mitchzavesky4734]

Everything that is manufactured is built to spec, with a tolerance. In order to reach "zero defects", the easiest way to do so is to expand your tolerance so it covers all variability. While it looks good on paper to have no defects, it will come at the expense of the customer getting inconsistent product. The right way to do so is gather information from your customers to determine an acceptable tolerance for your product, and with good processes and management, work to keep everything within tolerance.

[@ToniEhler]

What do you do if your process is not capable of meeting the customer's specification tolerances? What if your customer cannot accept anything outside of the spec tolerance? You are at an impasse and the only alternative is to inspect 100% which increases costs, scrap, processing time, etc.

[@miawang7632]

Achieving zero defects is a relentless pursuit of perfection in order to improve quality. Through this constant pursuit, we can push quality and improvements to a higher level

[@denisek743]

I always thought zero defects was the BEST anyone could do. I now know that we can do better by goal setting.

[@florahatzis5019]

This approach seems to focus less on acceptance and more towards perfection.

[@mattmack8103]

When you air for a target the goal is to hit the center "a bullseye", are you continually aiming for the center and hitting with minimal variation, or are you simply happy to hit the target?

[@fkiQuality]

You’re never going to hit the target always, because of multiple reasons called causes of common variation. The best that anybody can do is to aim for the target with minimal variation.
