Overview

I helped Starbucks' Improve the mobile ordering wait experience for customers who are waiting for their orders to be made.

Discover

What's the Problem?

I sought to improve the user experience for customers who are waiting for their orders to be made. Currently, customers may have to wait in line or at their table without knowing how long their wait will be. But with this new project, I aim to create a system that will make the wait time feel shorter and more enjoyable.

User Interviews

To initiate my discovery process, I conducted Zoom interviews with four participants to gain insights into how users utilize the mobile ordering process and experience associated emotions.

Research Goal

Identify perceived wait times, emotions, and pain points during mobile ordering.

Interview Questions

• What do users do after placing mobile orders?
• How do users feel when waiting for their mobile order?
• Why do users use mobile ordering?
• How long are current wait times.

Participants

Starbucks App users who utilize the mobile ordering feature at least a four times a month.

The Interview Process

  • Interviewed five participants ranging from ages 22-32

  • Interviews were held via Zoom

  • Interviews were semi structured with a discussion guide

Key Insights: User Interviews

4/4 Interviewees expressed being annoyed and frustrated when waiting for their orders to come out if its taking too long.

3/4 Interviewees mentioned that they like to hang out in their car to wait for their order so they don’t have to stand around.

3/4 Interviewees mentioned that they mobile order prior to going somewhere so they tend to be on a time crunch and they use the mobile order to save time.

Current wait times on app don’t always correlate with the actual wait times, leading users to feel frustrated.

Define

Empathy Maps

Following the user interviews, I gained valuable insights about my target users, which enabled me to create an empathy map capturing recurring patterns observed during the interviews.

Goals

With a greater understanding of the target user and their pain points, I proceeded to evaluate the business and technical constraints. This evaluation allowed me to establish a set of goals that would align the user's needs with the business objectives and provide a clear understanding of the project's scope.

User Goals

  • Save time during their busy day by quickly grabbing their order
  • Conveniently order their beverage/snacks
  • Be able to get their order on time consistently
  • Enjoy a high quality beverage or snack

Business Goals

  • Expanding its global presence
  • Innovating new products and services
  • Improving customer experience
  • Supporting ethical and sustainable practices
  • Enhancing employee engagement and development

Technical Considerations

  • Integration with existing systems
  • Performance and scalability
  • Accessibility
  • Security and privacy
  • Compatibility with different Devices and platforms
  • Cost and resource constraints

User Persona

With an enhanced understanding of my potential target user, I developed a user persona to solidify and define the characteristics of my target user.

User Journey

After Solidifying who my target user was I mapped out what emotions and possible touch points the user could have through out their mobile ordering journey.

POV/HMW Statements

Building upon the various empathy-building activities, I synthesized the gathered insights to create a point-of-view statement and a how-might-we statement. These statements helped to refine the problem at hand and identify the specific target audience I aim to address.

Develop

Ideating

Going Wide

During the initial phase of my ideation process, I deliberately explored a wide range of ideas, disregarding their feasibility, in order to ensure a comprehensive exploration. This approach was aimed at exhaustively considering every possibility, leaving no stone unturned.

Narrowing Down

Among the diverse range of ideas, I carefully selected three concepts focused on alerting the user, which I considered to be the most suitable solution for my persona.

Selecting Solution

Out of the three refined ideas, I specifically chose real-time updates on order status as the most promising option. I further expanded on this concept to ideate additional features that would effectively inform my persona about their order status.

How do these solve the HMW statement?

Deliver

Exploring Solutions

At this stage I began to wireframe different solutions. With feedback from my mentor and a panel of collages I found that the vertical progress bar would be the better solution to test for.

Current Confirmation

Horizontal Progress Bar

Vertical Progress Bar

High Fidelity Wireframes

From discussions with my mentor we decided upon three different stages of the ordering process which is shown below.

Usability Testings

With a functional prototype in hand, my objective was to validate the design's intuitiveness and its ability to instill user confidence in the mobile order pickup process.

Research Goal

Our goal is to gather data that quantifies users emotions waiting for their Starbuck's order.

Metrics

I asked users to rate their confidence in picking up their mobile order, using a scale of 1 to 7. I obtained ratings for both the original checkout process and the new progress bar feature.

Research Participants

Starbucks App users who utilize the mobile ordering feature at least once a week.

User Insights

Final Solution

Mobile Prototype

  • Customer can track order real time order status.
  • If enabled customers receive push notifications with other updates.

How I tried to design for emotion

  • I tried to provide a positive and memorable experience.
  • confirmation feature can help alleviate this anxiety by providing a positive and reassuring message that their order is ready.

Final Takeaways

Major learnings

Adding a simple feature like a cheers confirmation can have a significant impact on the user experience. It shows that even small touches can make a big difference in how users perceive and interact Starbucks. Through my usability testing I was able to quantify that user's on average felt 40% more confident when picking up their Starbuck's mobile order.

What would I have done differently?

If time permitted, I would have liked to explore more micro interactions to make the progress bar more delightful.
