Advice for PMs who are joining a new company: Your reputation as a PM will largely be made in the first 90 days. Maybe even 30 days, depending on the company.
Don’t be invisible. Build relationships. Bring energy.
Most importantly, get your team some early wins. Ideally within the first month of joining.
This is the advice I give to every new person who joins my team. I also give it to new PMs who DM me asking for advice.
It may seem like obvious advice, but you’d be surprised how few people follow it.
