The question:

Meet Andrew

Monday afternoon practice without Ultimate Sun

…then he gets another sunburn, and tells himself that he’ll definitely remember sunscreen next time…

He doesn’t apply sunscreen before practice – it’s not a habit

Monday afternoon practice with Ultimate Sun

Hot trigger = no sunburn!

Andrew receives an SMS with practice time, location, and sunscreen reminder

Results

Name Sunscreen without reminder?

Didn’t attend

Didn’t apply sunscreen

What Went Wrong?Why didn’t you apply sunscreen?

Timing: “I only attended [pickup] for part of the time.” – John

Motivation: “I tan well.” – Sean

Ability: “I don’t have any [sunscreen]!” - Ethan

Looking Forward:

ULTIMATE SUN 2011*

Leave No Player Behind: As part of the program, we will distribute bottles of sunscreen to every team member – nobody will be incapable of applying sunscreen

Quick Start: We will launch right at the beginning of the 2011 season to make Ultimate Sun a team staple

* Hypothetical

Thank you!
