Testing and Quality

Alan,

I have difficulties in understanding various manifestations of quality as you have articulated here ....

Product Quality - Intrensic to the product

Engineering Quality - Quality of all (engineering) processes that produce the product

Customer Quality - Eventually what customer cares about (will he buy it? will he recommend it?)

Except customer quality (which is a time-bound relationship between the user and the product), other two forms of quality appear to indicate that "quality is part or an attribute" of "process", "product"...

I just left a comment to your previous post quoting Michael Bolton that ... "quality is a relationship (1-1) but not an attribute of a thing ...

What do you say?

Let me put it differently.

I'm saying there are two kinds of quality: Engineering quality, and "Experience" quality. Engineering quality is a measure of how the product was built - Experience quality is what the customer sees.

I don't think engineering quality is process quality - i.e. I dont care how the process works, but I do care about the measurements. For example, I suppose there's a process to code coverage, but what I care about is the data.

Quality and the Experience

I'm beating a dead horse here (or at least beating an old post ), but I have a story to share about quality

Tester vs QA

上一篇談 Tester 的職責是什麼, 這一篇談另一個觀念, Tester 不應該被叫做 QA (quality assurance), 因為基本上, Tester 沒辦法真的確保 "Quality".
