--- name: design-a-service-transition category: start description: Design a service transition from project or incumbent operation into accountable support, monitoring, continuity, knowledge, access, supplier, and improvement ownership. Use when a new or changed service must enter steady operation safely. --- # design-a-service-transition Operational readiness includes people, evidence, authority, and failure handling. ## When to use - Use for launches, migrations, insourcing, outsourcing, vendor changes, or major service redesign. - Do not declare transition complete from document delivery alone. ## Procedure 1. Define service, users, components, environments, dependencies, criticality, hours, jurisdictions, and transition authority. 2. Identify current and target owners for product, operations, support, security, data, vendors, finance, continuity, and improvement. 3. Set service levels, experience measures, capacity, monitoring, alerting, escalation, incident, problem, change, and release processes. 4. Prepare architecture, configuration, inventory, runbooks, support scripts, known errors, contacts, contracts, and knowledge. 5. Transfer identities, access, secrets, licenses, assets, supplier obligations, budgets, records, and data through controlled paths. 6. Train and simulate normal, peak, degraded, incident, continuity, restore, and vendor-failure scenarios. 7. Run parallel support or hypercare with entry, exit, defect, backlog, acceptance, and rollback criteria. 8. Obtain operational acceptance from accountable owners and close project access plus unresolved obligations visibly. ## Done - A service-transition plan records service scope, owners, controls, knowledge, access, suppliers, simulations, acceptance, and residual work - Monitoring, support, capacity, access, incident, continuity, restore, supplier, hypercare, and operational-acceptance checks verify readiness
