It’s easy to assume you know who you’re talking to, but it’s just as easy to make a mistake. Every time you answer the phone, or phone someone else, make sure you really do know who you’re talking to.
I often hear people who work in IT operations complain that DevOps is just about development. If we want DevOps to work for everyone then we shouldn’t wait to be invited to join in and complain when we aren’t. We should actively adopt ideas from DevOps into how we run IT operations and seek out our development colleagues to foster collaboration.
