What is Quality?  (Software Quality)

Different people have different opinions about this term.  Let's explore the definition that I found the most appropriate:

From ISTQB (IEEE 610 standard):
Quality: The degree to which a component, system or process meets specified requirements and/or user/customer needs and expectations.


The term "requirement" should include both explicit and implicit requirements.

Explicit requirements are those that are clearly documented.  Implicit requirements are those that customers assume or expect to be fulfilled but not explicitly specified on any document.

However, do not underestimate the importance of the "implicit" part of the requirements.  Failure to meet implicit requirement may lead to unsatisfied customers which means deteriorating software quality.

The definition of "good quality" is simply satisfying users or customers' explicit and implicit requirements.
