What does a day-to-day activity of a TPM look like?

It could be a combination of any of these things -

• Look at data (dashboards, customer feedback channels, internal partner team feedback) to check progress (on product success, platform performance)
  -Take any actions necessary (filing bugs, resolving a SEV)
• Supporting your cross functional team to deliver on roadmap projects
  -Brainstorm product and technical solutions.
  -Sprints, design reviews, code reviews
  -Removing blockers
• Look at data to proactively surface opportunities, hot spots, technical bottlenecks etc
• 360 communications often tailored meticulously for the target audience
• A lot of meetings (Product reviews, Roadmap planning, Decision making etc)
• Ideating and planning for the future (Strategy)
• Upkeep or morale and motivation for team. TPMs often act as the glue for the entire team.
• And ideally they are having loads of fun doing all these

To me, the best part of being a Product Manager is that there is no typical day. There is a mix of working with your engineering partners, talking to customers, partnering with other organizations, and sharing info with executives or dealing with escalations. A day to day also differs greatly depending on the phase of your product.
