If you are at a point in your career where you want to make a change (new role/team/company/etc.), you need to take some steps to prepare your team and your replacement for success. Side note: I am assuming you don't want to burn any bridges. If that is your goal, this post isn't for you. If you move within the company and neglect to make the transition easy, you will likely be asked to cover your old role and will have a hard time succeeding in your new role.
