The answer is not "update LinkedIn". The first thing to do is apply the training to one real thing, this month, while it is still fresh and while people remember you did the course.
Days 1 to 3 - write the one-pager
Before anything else, write a single page: the use case you think is most valuable in your own function, what it would cost, what the risks are, and what a four-week pilot would look like. This is the artefact everything else hangs off. If your course produced one, sharpen it.
Days 4 to 10 - show it to one person
Your manager, or whoever owns the process. Ask for a reaction, not a budget. You are testing whether the problem is real to them, and putting your new capability on the record at the same time. Framing is in explaining your new AI skills to your employer.
Days 11 to 25 - run something small
A two-week pilot on a narrow task with a baseline measurement. Small enough that you do not need approval, real enough to produce a number. See starting small with AI.
Days 26 to 30 - write up the result
Problem, what you did, what happened, what you would do next and what it would take. Four paragraphs. This is the document that gets quoted when scope is handed out, and the one you will use in interviews later.
Then, and only then, the profile update
Certificate on the profile, with the project described underneath it. The project is what recruiters read - see what AI skills recruiters actually look for.
If you are certified but between roles
Same plan, applied to a public or volunteer problem. A written-up result on any real process beats an unapplied certificate in every interview. More in what to do after an AI certificate to get hired.
Keep the momentum
Fluency decays without use, and the field moves. How to stay current with AI covers a sustainable habit, and Leading AI Innovation & Organisational Transformation is the natural next step once a pilot needs to scale.
The bottom line
One page, one conversation, one small pilot, one write-up - inside 30 days. That converts a certificate into something worth having.
