Example of Price of Poor Quality (COPQ)

Quality assurance is everything for an organization. Incorporating 6 Sigma and other Lean tools, this allows companies to decrease waste (Raw materials, Logistics costs, and unnecessary man hrs) which increases their lesser line.

Let's say you lot are running a DMAIC project. In the define phase, you lot desire to quantify the cost of poor quality. You start by defining what a defect is, then measuring how many defects per one thousand thousand opportunities your process has. (You would utilize this same material to create your baseline sigma in the measure out stage, next.)

Case: Imagine producing TVs and for every 1M produced 2% were damaged… That'due south twenty,000 TVs. If those amercement were not salvageable, and it cost $100 to produce each unit of measurement, then it cost your company 20k *$100 = $2 One thousand thousand

Just that's not all. How many people would you work on re-inspection, warranty repair, supplier evaluation etc.? Here yous go for the breakup of the costs. Below are the dissever-up of various costs (Just equally an example).

Total material cost is $100 unit of measurement and an additional $x per unit spent on quality costs. At 20k units, that is $200k. The total price to the company would be $2.2 Million!

Why Pursue a Six Sigma Level of Quality / Excellence?

Let's use the aforementioned instance. At a 6 Sigma level you lot would only produce three.4 defects per million opportunities. In the previous example the process was making xx,000 defects per one thousand thousand. Moving to a six sigma level of quality would hateful 19,996.6 less defects per 1000000 units fabricated! That's a savings of $two.2M – (3.four * $110) = $2.2M – $374 … so, nearly $ii.2 One thousand thousand!

Avoid Errors

The best in whatever field figured out how to avoid errors very early on. We should, also, if nosotros desire to engineer a nifty process.

For instance, Simon Ramo notes that amid the very best lawn tennis players, to win y'all need expert winning shots; to be a good boilerplate thespian, you demand to just lower your failure rate. In practiced tennis, lxxx% of the points are won, while in amateur tennis, fourscore% are lost. The same is true for wrestling, chess, and investing: beginners should focus on avoiding mistakes, experts on making great moves. – Erik Falkenstein, Author The Missing Take a chance Premium
