Two years ago, I had the chance of introducing version control to a small development team, which have not used any kind of VCS for their code before. This is going to be a little case study on how it worked out after two years.
The company's primary profile was marketing and media, development was mostly considered a second/third class citizen. Most of the projects were very simple websites, either to advertise a client's new product, or to serve as the backend for a facebook app, or 90% CRUD for summarizing various surveys. Development time for projects was between 2-8 weeks, and without a written specification.
