As I mentioned in the question regarding your first 90 days, the first 30 days are all about establishing a baseline and assessing the current product marketing status. The first 3 things that I look for when onboarding are:
1) Audience strategy and research. Here I want to understand what’s known about the customer and their jobs-to-be-done. Specifically, personas and segmentation as well as any research related to acquisition and why customers purchase the product. This may also include any prior win/loss interviews and doing your own quick interviews with sales.
2) Current messaging. Look at as much of the customer-facing messaging as possible. This includes highly trafficked landing pages, sales collateral, recent campaigns, and messaging hierarchy templates.
3) Funnel and Lifecycle Performance Data. Here I am looking to understand what the major drop-off points are and the shape of the customer lifecycle. This helps identify areas for potential quick wins and gives you an early perspective on the typical sales or conversion cycle.
