Matthew gives the following definition:
| Defect.
|
| Cause of failure of a deliverable to meet its purpose.
One of the maxims that I remember from systems theory
is that Defects are gauged relative to a Design (QV)
or an Intention (QV), the Defect being then defined
as a Departure (QV) from the Design or Intention.
This is a little bit different from Matthew's definition.
In this usage, a defect is analogous to a symptom rather
than a cause, and so one is able to address real defects
in much the same way that one treats real symptoms, long
before uncovering their True Cause (Vera Causa), if ever.
This way or looking at things has an up side and a down side.
On the up side, one has a way of acting without being forced
to wait for knowledge of causes that may never come to light.
On the down side, remedies that do not address the cause are
likely to give only "fast, temporary symptomatic relief", as
they blurb, and so the corrective actions that are chosen on
the basis of partial knowledge are likely to need repetition.
