Jon Udell writes in Baseball lessons for software teams that new discoveries in valuing baseball players (based on the number of walks) are a lesson to be learned for the IT industry. ``Software development has an equivalent to the base on balls: a module that doesn?t have to be written new because it already exists and can be reused.'' I've never been a fan of any of the existing metrics I've encountered; KLoC least of them all. Jon highlights the effect of community involvement and reputation as clues to the value of developers.
