1) A platform as a product approach treats an internal platform like an externally-facing product by carefully designing it, evolving it based on user needs, and using modern product management practices.
2) This reduces cognitive load on internal engineering teams using the platform by simplifying tasks and providing optional, self-service capabilities.
3) Getting started involves assessing user needs, defining the platform, and determining team interaction models for collaboration and service delivery. Case studies demonstrate how platforms can evolve from basic services to sophisticated, widely adopted products.
