Kellan Elliott-McCrea has an excellent list of questions a team should answer before they decide to adopt a new technology in their software development process. For example:

If this new tech is a replacement for something we currently do, are we committed to moving everything to this new technology in the future? Or are we proliferating multiple solutions to the same problem? (aka “Will this solution kill and eat the solution that it replaces?”)

As he mentions in the post, these questions are not subtle… but I think they’re absolutely essential. It reminds me a little bit of Marty Cagan’s Product Opportunity Assessment questions.
