How do you define success as a Platform Product Manager?

As a Product Manager, you are responsible for:

1. Defining product vision/strategy/roadmap based on deep understand of customers, business and competitive landscape

2. Working with various cross-functional stakeholders and partners to execute on your roadmap and ship product/features

3. Establishing processes to gather customer feedback to continuously evolve the product

Platform Product Manager role is very different except the product is a platform and hence your customers are the ones using the platform. Exact customer persona will depend on the specifics of the platform. Success is typically measured by adoption of your platform, customer satisfaction and the business impact your platform has.

Platform PM is a specialized role that requires technical chops and soft skills to work with external and internal customers and stakeholders while being able to go deep in the weeds but also think about the big picture of what the platform can do. As a result, there are a lot of dimensions on which success can be measured.

The two main dimensions for measuring success are adoption and technical excellence.

1. Adoption - how is the platform being adopted, how many teams are utilizing the platform, how big is the partner ecosystem and is it thriving, are adoption goals met

2. Technical Excellence - is the platform extensible via APIs, is the platform able to handle the scale, is the platform reliable, are there any outages that are affecting teams and their SLAs, how easy it is for teams to debug and find issues, what is the pace of innovation
