An extremely short book that’s almost militant in its espousal of the SaaS mindset. It works as a sort of primer for people used to some other paradigm of software delivery to “re-program” them into a SaaS perspective. It covers everything (very briefly and superficially) from development cycles to support to sales, etc. This is not a comprehensive book, but it works for what it’s meant to do – to push SaaS as a paradigm shift, different from other patterns and with it’s own methodologies and practices.
