 My role:

Research • Interview • Design 

​Team: Tom York, Beth Dunford, Payton Cheney, and Zoey Kaelberer

May 2020 - July 2020

Goal: to help people make healthy choices in regards to immunizations

The first step we took was to identify assumptions, research the needs or problems and questions needed to answer them. 

Our assumptions:

1. People are split into three categories - Pro, Neutral, Anti

2. Immunizations are only a conversation for parents (what about single people and older adults?)

3. People are split on the health consequences (pros/cons) of vaccines

4. People are confused and on the fence about what to do

5. People make decisions based on family, friends, their doctors, social media, or etc

Persona

We created a survey with the questions based on the assumptions above and conducted a few interviews to create our persona. To gain more insight on the different opinions, I held interviews with someone who was against 

We had over 200 people take the survey, which we used to create our persona: Charlotte, a married mother of two who wants the best for her children but some frustrations are keeping track of whats required while staying up to date and a concern with side-effects. 

We selected a mother as our persona since 88% of our respondents were mothers and most mothers handle and organize this information for themselves and their family. Also with the intention of building this app to be simple enough for a busy mother to use, this would assist us in designing functionality with a high level of ease to use. 

Lo-Fi Prototype

We sketched out wireframes based on our user story map and divided the work and sketched out the pages based on the three main user tasks and the pages we felt were most valuable and held usability tests, both unmoderated and moderated. 

Initially we wanted the main goal of the homepage to be a sign up page, but quickly learned in testing that people are more likely to have incentive and sign up if they can see value in a product or service. We focused on the main wireframes that we needed which were the home page, the goals, and signing up and the interaction pages in between that would lead to each page.

 Usability Tests

Our research goal was to fully observe and improve the overall VaxTrax website user experience. So we conducted formative usability tests to identify problems that needed improvement, observed participants conducting a variety of typical tasks while using the website and gathered real-time feedback for iterative design updates, and developed short and long term solutions to improve overall experience. We had 6 tasks for our users to go through, below is a list of our tasks, the feedback received, and the quantitative metrics. 

We had six tasks we asked users to complete. 

Task #1: Create an account - need to update "About Us" page; overall high marks

Task #2: Update your profile - need to make arrow more prevalent

Task #3: Learn more about a vaccine - banner blindness of "Learn" in main menu; need to add content that defines what this is

Task #4: Log a vaccine - easily found after learning system setup; should include list of vaccines instead of scroll option

​Task #5: Add someone to family -  need to make plus button much more prevalent

Task #6: Modify vaccination schedule - need to add a "save" button; need to include a notification option

Quantitative Metrics

Task Success: 16/18=85% (66%-98% confidence interval)

SEQ: Average 6.41 (5.9-6.93 confidence interval)

TOT: Geo Mean: 14.84 (8.4 - 26.3 confidence interval)

NPS: Overall score of 20

SUS: Overall score of 90.8

Our second round of testing, we did hi-fi prototypes and most of the feedback we received were on copy and clarification. We created a brand/style guide so that the different pages we all worked on would look consistent. We chose the colors teal and orange because it felt modern but also professional.
