What good is high-quality software that takes forever to code or low-quality software delivered in a jiffy? Real Web development, the one you get paid for at the end of the month, requires maintainability, productivity, and quality to be feasible.

As we discussed earlier, software quality is closely related to testing. One way to measure software quality is verifying how close its features are to what is expected of it. This kind of measuring does not take into account the subjective side of quality evaluation. A client, per example, may believe the design of his latest project is ugly and consider a well tested, feature-adherent Web project crappy. The most you can do in these cases is charge a few extra bucks for a design refactory.
