Canvas vs. model-driven: choosing deliberately
Canvas apps offer pixel-level control ideal for task-specific processes; model-driven apps excel for data-centric applications with complex business logic on Dataverse. Enterprise architecture should choose deliberately, not default to whichever tool a team already knows.
Component libraries and reuse
Centralized component libraries — for navigation, forms, and common UI patterns — reduce duplication and let teams update shared elements once instead of across dozens of apps.
Separating data, logic, and presentation
Pushing business logic into Power Automate flows and Dataverse plug-ins, rather than embedding it in app formulas, keeps applications easier to test, maintain, and hand off between teams.
Performance considerations
Delegable data sources, minimized nested formulas, and careful control counts per screen all materially affect how an enterprise Power App performs once real users and real data volumes arrive.
// Example: delegable filter pattern for large Dataverse tables Filter( Projects, Status = 'Active' && Owner.Department = varUserDepartment )
