Martin Fowler’s blog about technical debt suggests there are two axes of debt: deliberate and prudent. This creates four quadrants: deliberate-prudent, deliberate-imprudent, inadvertent-prudent, and inadvertent-imprudent. Robert Martin talks about the dangers of thinking you are in the deliberate-prudent quadrant, while you actually are in the deliberate-imprudent one.
