Platform engineering is essential in building internal developer platforms at the enterprise level, as it allows companies to treat their platforms as products and focus on delivering value, high-quality, speed, and optimizing for the developer experience. A generative culture is crucial for platform success, and companies should prioritize speed over cost. Platforms need to be designed with the customer in mind, including minimizing burden and making it easy for consumers to access and use them. Team leaders must set clear outcomes and create an environment where teams can work together to make something happen. The key to successful platforms is to start small, learn before scaling, and design for joy, which includes making problems visible and setting up a system of accountability.
