Problem and data
Define workflows, permissions, data sources and decisions needing human review. Model quality and correct software behaviour are separate acceptance criteria.
Development and integration
Develop web, Windows, mobile or API components for existing systems. Define model services, validation, queues and reporting. Keep version and error contracts explicit.
Evaluation and deployment
Include access control, personal data, testing, monitoring and secure updates throughout the lifecycle. Define workflow behaviour when the model is unavailable.
