• Miro
• Maze
• Hotjar
• UserTesting.com

PAGE 22 — Economic Significance

UX design drives:

• Digital transformation
• Customer retention
• Reduced operational costs
• Higher productivity
• Better public service delivery

UX is the difference between digital success and digital failure.

SECTION 5 — CYBER SECURITY (Pages 23–29)

PAGE 23 — Definition & Purpose
