When starting a new job, what are steps you've taken to develop a 30, 60, 90 day plan for yourself?

"I like to take the first week to meet people and look at the data to see what the story is. also love to ask questions... many times, people within the department have thoughts and feedback that becomes really important. I then start carving out the 30/60/90 day plan and ask my leader for feedback to see if s/he agrees or has any other initiatives they believe are important that I've missed. Keeping the lines of communication open is very important at the beginning!"
