It’s pretty easy to overlook some of these. Make an actual checklist and don’t forget!
To ensure a launch process goes smoothly I like to create three checklists. A pre-launch checklist covers everything you need to do a few days before launch to ensure everything is prepared. A launch checklist outlines the actual process the launch team will go through during the launch window itself. And a post-launch checklist details a variety of tasks you can’t really do until the site is live, and you do a few days after launch.
