What are generally the top priorities you would address during first months in a new job?

This is a question asked on LinkedIn: In a new job, what are generally the top 5 priorities you would really address during the first month and then the two following months ?

One of the answer was:

First month:

- Know who is who in what places. DON'T judge
- Know the systems you have to work with
- Know your job and who is your client, internal or external
- ORGANIZE yourself
- LISTEN to people, NO MATTER WHAT

2 next months:

- Get involved in projects that will help you know you job
- Know the daily routine of your direct report
- Get in better touch with the clients
- Know what the problems are and what you are really facing
- AND NEVER TURN YOUR BACK ON A PROBLEM. It won't go away

May you be successful.
