What is the difference between declarative and programmatic customization?
Real World Scenario
Project team debates Flow vs Apex for every requirement. You explain when each layer fits.
Expected Answer
• Declarative tools include Flow, validation rules, formulas, page layouts—configured without code
• Programmatic means Apex, LWC, Visualforce—code deployed through dev pipeline
• Declarative is faster for admins to maintain and upgrade-friendly
• Programmatic handles complex logic, integrations, and performance-critical bulk processing
• Healthy orgs use declarative first with clear criteria for code

Yes—Flows can DML, callouts, and loop badly. Treat complex Flow like code with testing and change control.
