We can expect 3.4 defects per million opportunities.
.4 ppm means that the opportunities or likelihood that the product/process will fail is 3.4 in a million. like for an instance when you bought a single lottery ticket. the chances of winning is only 3.4 out in a million or 0.00034%. in terms of defects the chances that the single product/process fails is only 3.4 out in a million. it is totally different of saying that producing one million parts you are expecting 3.4 defects which a lot of people misinterpret.
If the DPMO figure was factual data, and not the random value i came up with for my perfect example, would it be safe to say, that a computerized production line that printed Colorado Lottery Scratch Game Tickets, did so with a 3.1DPMO, and level 6 excellent, and not just of good quality. and then add that this game not only looks beautiful but it also has a 1:5 overall winning odds, then odds of winning a top prize jackpot is a 1.8 ppm. is it safe to compare the ppm to DPMO, cause id say the printing process is extremely flawed if the DPMO exceeded the ppm of odds of winning yop prizes. if theres the chance that the defectedtickets that didnt print could actuallt be the top prize winners, and change the odds of winning to odds of losing.
The answer is A. 2, 5, 1, 4, 3, Define, Measure, Analyze, Improve, Control
Six Sigma is a disciplined, data-driven approach and methodology for eliminating defects (driving toward six standard deviations between the mean and the nearest specification limit) in any process – from manufacturing to transactional and from product to service.
In a nutshell, here are the key principles of Lean Six Sigma Business Transformation to bear in mind:
Focus on the customer.
Identify and understand how the work gets done (the value stream).
Manage, improve and smooth the process flow.
Remove Non-Value-Added steps and waste.
Manage by fact and reduce variation.
Critical to Quality (CTQ) Trees help you translate broad customer needs into specific, actionable, measurable performance requirements. You can then use these requirements to deliver high quality products and services. CTQ Trees were originally developed as part of the Six Sigma methodology.
"Six Sigma is a quality program that, when all is said and done, enhances your client's understanding, brings down your costs, and assembles better pioneers. It tries to enhance the nature of the yield of a procedure by distinguishing and evacuating the reasons for absconds and limiting changeability in assembling and business forms.
It utilizes an arrangement of value administration strategies, principally observational , measurable techniques, and makes a unique foundation of individuals inside the association who are specialists in these strategies. Every Six Sigma venture completed inside an association takes after a characterized arrangement of steps and has particular esteem focuses, for instance: decrease process duration, lessen contamination, diminish costs, increment consumer loyalty, and increment benefits.
Geometric Mean is not a Measure of Central Tendency.
There are three types of Measures of Central Tendency. Let's talk about them one-by-one:
1. Arithmetic Mean: It is the total sum of all observations of a data set divided by the total number of observations. It is also called arithmetic average.
2. Median: It is the middle value in the given data set after arranging them in ascending or descending order.
3. Mode: Mode is the most common value that occurs in the distribution.
The answer to this is D. You should not continue as it will be harder for you to figure out what the special causes in a control chart is. You have to know and determine what the special causes are and you have to make an effort to eliminate them. If there are a lot, then eliminate them one by one. If you would continue taking data measurements, the special causes may worsen and may even multiply.
You also cannot just figure out what the special causes are, then go through the process like as if nothing happened. You need to eliminate them to be sure that you will not encounter other issues in the long run.
