Robert Pirsig’s 1974 bestselling classic, “Zen and the Art of Motorcycle Maintenance” was not about Zen or Motorcycles - although both made an appearance.

Quality, it turns out, is very hard to define. Software Quality is no different. When someone talks about software quality, what do they really mean? How do we measure it? How can we improve it? How do we know when we have it?

But over the years I’ve been working to establish what I think are the most important aspects of software quality, how they work together (and sometimes against each other) and how we need all of them (even if they sometimes come as a set).

In Pirsig’s semi-autobiographical novel, we are taken on a motorcycle journey from the east to west coasts of the USA. Our journey will take us through the territories of tests, types and static and dynamic static analysis - with no mention of east or west const.
