Evaluation
Task Flow:
View Offers. Place Order.
Impressions of the McDonald’s mobile app have been that of frustration and astonishment. For such a powerful establishment, McDonald’s has come well short in delivering a mobile app experience worthy of their reputation. The simple task of viewing special offers and making an order is not as simple as one would expect and is visually unappealing and confusing.
Scoring System
0 - No issues.
1 - Not major. Fix only when there’s time.
2 - Minor issue. Low importance to fix.
3 - Major issue. Important to fix.
4 - Fail. High priority to fix.

Redesign
To uphold McDonald’s reputation of being a quick, familiar, and convenient choice for fast food, tweaks were made to the current flow and design. Through these changes, the flow of choosing a special offer, selecting required items, and purchasing has been simplified by reducing the amount of steps, and increasing the discoverability of key information.
