Below is my draft list
* Be patient and listen, listen and listen without any judgment. There is no better friend than active listening. * No one likes a know-it-all - Be honest, confident and humble * You will still do something embarrassing. And you will survive. You can't improve if you are worried about your mistakes. Don't worry about it! * Observe what everyone is doing. Ask questions. * Be comfortable asking others for help or referencing documentation, Try not-to-figure-out-yourself unless that is expected * Follow Before You Lead, * Be tolerant of practices that are foreign to your established approach. * Mastering established team practices and rituals builds trust. * Automating an existing process is likely to be better received than making an independent decision to replace an existing tool. * Spend some of your personal time masterings and enhancing tools the team uses. * Ensure your output is reviewed by an existing employee before it is rolled out.
