Robert Pirsig's 1974 bestselling classic, "Zen and the Art of Motorcycle Maintenance" was not about Zen — or Motorcycles — although both made an appearance. The subtitle gives you more of an idea: "An Inquiry into Values" but it was only later that the main concepts in the book, along with the sequel, "Lila" came to form part of "A Metaphysics of Quality".
Quality, it turns out, is very hard to define. Software Quality is no different. When someone talks about software quality, what do they mean? How do we measure it? How can we improve it? How do we know when we have it?
We have no shortage of incomplete candidates for these definitions. But over the years Phil has been working to establish what he thinks 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 the west coasts of the USA. Our journey will take us through the territories of tests, types, and static and dynamic analysis — with no mention of east or west const.
