Some people think the moment they buy the tooling – everything else just happens. “We would never think like that” you might say as the experienced reader, but look at your behaviour and that of your colleagues. Did you really think about the steps beyond getting software installed. Who is going to look after the new shiny tools, how are you going to work, where is the infrastructure, who enables the people who use the tools, are there new techniques that need to be learnt, who is going to think about new versions, how do you change the way you work. This is not meant to put you off, but just a plea for some thought into these topics. My colleagues and I who write these posts often see this lack of forethought, and we really would like you to be more productive and happier.
One of my colleagues, Peter Eeles, has written about this in more detail – you may want to look at his material here http://www.architecting.co.uk/presentations/The%20Rise%20of%20the%20Development%20Environment%20Architect2.pdf
