How does PMM at Miro work with Product before they decide what to build next? Is there an opportunity proposal phase where PMM and PM work together?

Similar to most of the other companies I've been at, we do quarterly OKR planning with the Product, Engineering and Design teams. Miro has become more and more Enterprise driven, and as a result, much of what we build is a combination of features that help us become more Enterprise ready (security and compliance ready) and a list of customer requests to manage users. During this OKR planning process is when PMM and PMs work closely together to confirm and finalize the plans on what we want to launch and build for the quarter. However, this is not the only time when we decide on what to build next, throughout the year, we both work with UX designers, get on calls with customers, and brainstorm based on industry standards on what to priortize and how to build it.
