My role: Lead designer
Although CareerFoundry only required me to design a recipe app for Amazon Alexa, I wanted to focus on a specific problem space so that my Alexa Skill would provide a more refined service.
Noticing the poor snacking habits of my peers, I decided to create an Alexa app that would help users make healthier choices. Poor snacking decisions are often made when people are busy or stressed, so I focused on creating an app that would guide users in making nutritious and delicious snacks in 5 minutes or less.
Because this was a design sprint project, I simplified the standard double-diamond approach into a two-step define-design process.

After watching my professional friends make poor snacking choices, and being guilty of eating unhealthily myself, I was curious. How could people be motivated to make healthy eating decisions while still supporting their busy lifestyles?
I conducted guerrilla interviews with five friends and family members. Focusing on the experiences of my target users—busy professionals—helped me empathize with their struggles and deepened my understanding of their needs.
Based on my findings, I quickly sketched out the user persona Olivia:
To inspire Olivia, I designed Pietro, a young, professional chef who wants to help people cook healthy, delicious food.

User flow for voice
With the personas and user flows in mind, I designed the voice scripts (Appendix B) for 5 Minute Snack Bar:
