Power Apps – Enhanced UI Development — Lesson 4: Performance and UI Quality

Learning Objectives

• Reduce repeated formulas, unnecessary controls, media size, and data calls
• Test responsive behavior across devices, orientations, and user roles
• Create UI review, usability testing, documentation, and improvement standards

Detailed Topics

• Reduce repeated formulas: Reduce repeated formulas, unnecessary controls, media size, and data calls
• Test responsive behavior across devices: Test responsive behavior across devices, orientations, and user roles
• Create UI review: Create UI review, usability testing, documentation, and improvement standards

Guided Demonstration

1. Review the requirement, users, data, dependencies, permissions, risks, and expected result.
2. Demonstrate the relevant configuration, application, automation, analysis, or administration workflow step by step.
3. Capture settings, outputs, logs, screenshots, calculations, test results, and other useful evidence.
4. Compare the observed result with acceptance criteria and explain any corrective action.

Hands-On Activity

Run a UI quality and performance review.

• Document assumptions, prerequisites, and the planned sequence before starting.
• Complete the activity and preserve evidence of normal, boundary, and failure behavior.
• Record issues, corrective actions, reusable notes, and the next improvement priority.

Scenario Analysis

• Identify the business or technical decision that must be made.
• Compare valid implementation approaches and their trade-offs.
• Consider security, privacy, accessibility, performance, support, and operational impact.

Troubleshooting Focus

• Separate symptoms from causes and collect evidence before applying a fix.
• Check configuration, data, permissions, dependencies, capacity, connectivity, and recent changes.
• Validate rollback, recovery, ownership, user impact, and business continuity.

Validation Checklist

• The requirement, scope, inputs, and expected outcome are clear.
• The selected design or configuration is documented and follows approved standards.
• Normal, boundary, failure, security, accessibility, and operational conditions are reviewed.
• The result is supported by evidence and the next improvement is prioritized.

Lesson Outcome

Learners can explain and apply Performance and UI Quality in a realistic scenario and validate the result with documented evidence.
