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.

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.

It makes sense that monitoring the output has limited value - in our company's case it is also not feasible for many of our highest volumes part to be reworked.

Hi Shannon, it is equally important to know when to avoid making any changes to the process because slight changes have no meaning. We'll see this in class next week.

To avoid defects, there should definitely be QC checks within the process. Avoiding rework and scrap should always be a top priority for an organization. Ultimately, the goal should be to fix the root causes if possible.

In-line or intermediate inspections are critical so that defects can be caught early on in the process. However, that is not sufficient. When defects are discovered, there should be an analysis performed to identify the root cause(s) of the defect. Once the root causes(s) is(are) discovered, preventative measures and corrective actions should be put in place to minimize the likelihood of those root causes triggering those defects again in the future.

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.

Having to catch a bad product right before it is to be shipped to the customer is expensive and can result a late shipment of parts. Fixing defects right at the source is the most efficient way to go.

This video was helpful in describing both QC and QA. I’m very familiar with both of them. But I found it interesting to learn that both of them are problematic because they focus on the product already made or the service already delivered. But I do agree that seeking to build quality in every step of the production process would be a great way to go.

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.

@ChrisLenart-e9u 20 күн бұрын
I had not considered QC and QA as separate entities. While the additional inspections between operations do help catch the defects prior to additional value being added to the parts, it does not address that quality needs to be built into the process. It is still treating quality as a separate process and demonstrates why we need to be using dmaic tools to reveal the root cause of problems so they can be addressed.

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.

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!

I now understand the difference between both QC and QA. Both are problematic and costly; we need to focus on the product that has already been made the 1st time. We should look to build quality in every step of the process to prevent many reworks, should be fixed at the root cause from the beginning.

QC and QA have been the assumed means of ensuring defect-free products for most people. This is a nice detailed explanation of why a better approach is needed. However, aren't the QC and QA methods the means by which many educational classes are run? We only find out that Johnny wasn't understanding algebra or history when he failed the tests and quizzes.

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.

I appreciate the use of the control chart. I would like more detail on how to filter out the noise from normal variations that are reflected in the data. It sounds like the control limits should reflect a certain tolerance for variation. But how do you account for this tolerance if the target is given to you rather than a target based on historical data? Can you annotate the occurrences in the chart somehow?

This video in my opinion is a good example of how easy it can be for managers to over-react when looking at the numbers regarding operational expenses. As was pointed out in this video, it’s the control charts that truly show the behaviors of an operation, because it’s the control chart that filters out the noise so that action can be taken upon real signals.
