Best practices. For many, a four letter word followed by "change." Recently, best practices got full press with standard-compliant HTML and CSS webpages. Presto chango, a one click validator later, and best practices became the norm. Anyone trying to debug an AJAX widget can tell you, the best practices described by the W3C just works. Unfortunately, the same diligence is often ignored in areas outside of HTML, which is a big shame. Best practices evolve, and all areas of a business need to be actively assessing their own procedures for optimization.
