The V-model is a term applied to a range of models, from a conceptual model
designed to produce a simplified understanding of the complexity associated
with systems development to detailed, rigorous development lifecycle models and
project management models.
There are several radically different forms of the V-model, and this creates
considerable confusion. The V-model falls into three broad categories.
Firstly there is the German V-Model "Das V-Modell", the official project management
methodology of the German government. It is roughly equivalent to PRINCE2, but
more directly relevant to software development. What is probably the earliest use of
the V-Model as a basis for a standard is Software Development Standard for the
German Federal Armed Forces, 1992. The key attribute of using a "V" representation
was to require proof that the products on the right-side of the V were acceptable by
the appropriate test and integration organization implementing the left-side of the V.

Armed Forces, V-Model, Software Lifecycle Process Model, August 1992>
Most [people] have the ridiculous notion that
anything they do which produces an income is
work — and that anything they do outside
‘working’ hours is play. There is no logic to that.
William J. Reilly, How to Avoid Work, 1949
