Background
AMBASSADOR: A BEER, WINE, AND SPIRITS MOBILE APP
With over 8,000 employees serving more than 100 brands to over 9 million customers, Constellation Brands Inc. needed an innovative way to help internal employees support and enjoy their brands at social events. That was when the Ambassador App was created: a mobile navigation app that allowed employees to find locations that serve and sell from CBI's portfolio of beer, wine and spirit products.

The Problem
BRAND ADVOCATES LOSING REVENUE DUE TO APP INEFFICIENCIES
Sales reps (aka brand advocates), the primary users of the Ambassador app, spend a long time planning their brands portfolio before, during and after meeting their customers. Because planning is done manually — using Excel spreadsheets, printed paper lists and jotting notes on the phone — sales reps find it tedious to use the Ambassador app. Many have complained that keeping track of products and finding product information takes away from the time they can spend socializing and engaging with the customers. This is a problem because, when customers don't feel the connection with the sales reps, the business risks losing revenue.

The Solution
AN ELEVATED & INTUITIVE APP WITH A PERSONAL TOUCH
The Ambassador 2.0 concept I created is an elevated, intuitive and visually stunning app with a save-to-list function for all products.
Given the 4-week time restraint, I focused on improving the branding and product portfolio aspects of the Ambassador app.

Future Considerations
If my team and I were allotted more time and resources on this project, here are some next steps I would take for this mobile app redesign:
- Some users had reflected that they mainly use the search bar to look for products. I would like to consider this change in the next iteration and perform A/B testing on open vs. closed search bar.
- The scope of this project focused on creating visualization and context for CBI's brands and products. In the next phase, I would like to explore how the navigation aspect of the app will look like with the new branding.
- Further user testing for the "My List" screen is needed to determine what other features users need for product management.
