SMB Product Marketing

I'm new to Product Marketing. In the interviews that I've done, I am being asked to present a marketing portfolio.

I work in a company that measures the impact of all projects, but admittedly this is a difficult area to track. Would love to any suggestions/thoughts.

Where does all that time get repurposed in self-serve PMM? What are some of the big categories of work where you over-invest in self-serve vs. traditional B2B PMM?

Our sales team is focused on mid-market / enterprise and our partners drive our SMB revenue.

If targeting entreprise customers requires ABM and a heavy sales movement, is it still possible to do PLG?

I interviewed earlier this year and did well except for this assignment. I'm hoping to better prepare for similar situations. Here's the quest: As mentioned, the next part of this process is to complete a brief assignment. The purpose of this assignment is just to see your methodology get some insight into your approach to tasks. For this assignment, I'd like for you to create a high-level go-to-market plan and strategy for our flagship product our event marketing platform. Our company traditionally has targeted enterprise b2b companies. I'd like you to come up with high-level messaging, define who the target audience is, and then detail your strategy for informing the market about our event platform and getting more leads. Please identify which channels you would use, and what you would need for this go-to-market launch. Please keep your response under 2 pages

I already have things like Customer Visits, a Sales Enablement / Content Management tool, SKO, pricing model consulting.
