Internal Developer Platforms (IDPs) provide freedom of choice and abstraction levels tailored to individual developer preferences, rather than a one-size-fits-all approach. This allows developers to work efficiently while maintaining context about how their code runs in production. The key mistake is designing platforms for few experts while leaving the rest without context, leading to "shadow operations" where senior engineers are blocked, resulting in 78.8% of cases. IDPs aim to simplify and provide context, structuring yet embracing the unstructured, and matching developer ability with the right level of abstraction. By offering self-service capabilities paired with deep technical expertise, IDPs promote an informed, healthy, and productive engineering team.
