Ventajas
There have been a lot of changes in the last 12 months. We're changing everything about how we build software, for the better IMO. It came at the right time for me, I'm being challenged much more than I used to be. While not perfect, engineering concerns now take a much higher priority than before. We're moving away from a .net walled garden to a multi-platform distributed stack - some node.js, rails, also java in addition to C#. Also getting our build & deploy house in order, working towards continuous delivery.
Desventajas
Change doesn't come easy, I guess. We seem to make progress in waves, but still get held up with manual processes, particularly in ops. But it is getting better. Puppet and Chef are starting to make life easier there.
