I came from the technical side and did the PMI PMP and PMP ACP. I know people are rightfully critical of certifications here, and certifications alone never teach you the thing they certify, but for me it was worth it.

I learned a lot of lingo I was unfamiliar with and the broad and comprehensive treatment of the field gave much more confidence. Being forced to deal with all the topics in PM, at least to some degree, was very eye opening for someone like me, whose experience was restricted to only certain aspects of it.

And not the least, it gives you access to people in similar positions in other organizations and industries for exchange and to learn from.

EDIT: If you meant PM as product manager this is probably not for you. I was curious how common PM for product manager is and searched HN for the abbreviation. Most commonly on HN it stands for - surprise, surprise - prime minister.
