Where it matters
A product works in a prototype but is not ready for real users, or a critical workflow has become hard to change safely.
What this discipline brings
- Product and API boundaries tied to the workflows people actually use
- Identity, data rules, and failure behavior designed into the application
- Automated checks and an observable release path
- Documentation and handoff in client-controlled systems
Product engineering is usually part of Productionization & Modernization. The scope follows the system and its acceptance criteria, not a preset stack.
