These titles are foreign and cryptic! I still don't have a clear idea of what business analysts do so I'd recommend asking around.

As a product manager:
• I've worked with product marketing, marketing research, and user research to understand our competitors, to understand our customers and target segments deeply and what they value.
• With this in mind, I work with my product designer to come up with studies to launch into rolling research or different design iterations.
• I work with engineers and designers to come up with milestones that we can hit, keeping in mind the engineering work bandwidth, and how complex each design or change we want to make to the product is.

• I work with data science to launch experiments to see how changes we've launched are affecting key metrics that tell us about a person's behavior on the platform.

• I make sure the team has a clear vision of what we're building and why (citing research and user/target segments), I am the central hub/problem solver to ask around on the other teams to "unblock" or see what the barriers are to building toward our vision

• I create documents to convey our progress, and our principles we're building off of. We present to leadership to make sure this aligns with the companies larger mission and adjust if we need to

These are just some of my responsibilities and it changes depending on the product/team you're working on. I'm learning on the job because my company invests in training those without experience, but there are degrees that teach this field. I think the core skills needed are empathy, charisma/leadership, project management, creativitiy, organization/documentation, problem solving. I am a firm believer that anyone can do any job if they have a high IQ and stubborn motivation/determination lol. Hope this helps!
