Testing quote of the day

[jenk]

From Software Testing Fundamentals: Methods & Metrics by Marnie L. Hutcheson, under "Traditional Definitions of Quality That Are Not Applicable". (A few comments in blue are me.) Philip B. Crosby is probably best remembered for his book, Quality Is Free (Mentor Books, 1992). [...] The major emphasis is on doing things right the first time. Crosby maintains that this quality is free and that what costs dearly is the rework that you must do when you don't do it right at the get-go. According to Mr. Crosby's teachings: The definition of quality is "conformance with requirements". Assumes clear requirements! The system for achieving quality is "prevention, not cure". Assumes you know all the necessary pieces before you get started! [...] These conceps are most certainly laudable, but they require a very high level of discipline and maturity to carry out. The fact is that this set of concepts doesn't fit the commercial software development process. [...] Overplanning and underplanning the product are two of the main failings in software development efforts today. Coming from the shrinkwrap world, I've seen the dangers of underplanning. How can overplanning be a concern? Hint: What are you building? What's your budget, and what's the best use of it? At what point are you spending more money on process than you will be able to recoup through sales?
