A quality problem?
You recognize this?
"The quality of our products must be structurally improved. The warranty costs are too high again"
And what happens next?
Several quality initiatives are started. One of many in the past. Sometimes combined with organizational changes. Modifications in the product are introduced and finally after a lot of time and costs the quality level is reached as wanted in the first place.
Until the next product is released to the market. Then history repeats itself. Not always but too often. Obviously it seems not possible to create the wanted quality from the beginning. Why? There are many good reasons for this. Without doubt one is able to compile a full list of reasons why it failed again despite all effort. On this list the next cause should be present as well.
There is no quality problem!
Nice, but what else can it be?
A lot of so called quality problems, occurring year after year are probably no real quality problems but might be something else. Therefore all actions dedicated to improve quality are doomed to be less effective as hoped for or even a complete failure.
According to Relia-Easy this could be caused by focusing on the wrong cause. It is not a quality problem. It is not a reliability problem. It is an unreliability problem. That is something else and requires a different approach.
Relia-easy's articles are not about quality problems. There are many books available about that subject. It is also not about reliability problems because they can be solved relatively in an easy way. There is enough literature present to help with this matter.
Relia-easy's articles are about unreliability problems, because these causes are easy to identify but very complex to solve. There is not much literature present or too complex to be useful. Relia-easy tries to simplify.
