Challenge 3: Usability Evaluation and Site Redesign


In this exercice we have to :
- conduct usability evaluation by comparing 3 travel apps
- perfom usability testing
- redesign part of one app by making wireframes to improve it.

The methodology

i choosed to focus on a young couple

Young couple — 20–40 y/o (2)
You and your partner decide to go to a special place next summer. You realize you have both saved enough for the tickets and are planning to save as much as possible for the next 6 months to do this trip. You want to be efficient and have everything you need organized to enjoy at 100% while there. Even if you’re young, you want to have special moments to celebrate being together.

And for the sutdy we’ll imagine going to Taj Mahal in India.

I searched out some information about my destination, that is:

  • Closest airport: the IGI Airport of New Delhi
  • Currency: Indian Rupee
  • Medical needs: Measles-Mumps-Rubella, Tetanus-Diphtheria-Pertussis, polio vaccines
  • Passport: Your passport must be valid for 6 months from your date of entry into India
  • Tourists visa: you need to have a tourist visa before enter the country

After the researchs i started benchmarking Skyscanner, Kayak and Tripadvisor.
For that i used Usability Heuristics evaluation with Nielsen’s Principles.

Usability is important because it refer to how is it easy to use the product.

In usability heuristics evaluation we compare products with the 10 nielsen’s principles.

By doing this analysis of the 3 apps with the needs of my user type the one won was Tripadvisor. One of the reasons is that it offer not only hotels and flights but also experiences.

After i defined the best app for my user type, i have to interview some about the app to better know them.

So i interview 3 couples :
Laura & Guillaume (34 & 36)
Alexandre & Suzie (29 & 30)
Jeremy & Elodie (29 & 28)

I asked them to plan a trip from Paris to Taj Mahal for July 2022. They only had to book the planes/train/bus they need.

From the feedback I had, the most revealant was :

Usability: we cannot book flight using the app, but only on the website. So we have to do it throught the smartphone’s browser.
Assist during the travel : we cannot book taxi or other alternatives to go to the airport
Clarity : the “plan” section is not clear. We only can save places but not create a “timeline” who might be helpful to plan the travel.
Main page : We cannot make a search direct from the main menu.

First i redesigned the main page to add a search bar with categories. I made 2 propositions with one more precise than the other.

For the plan section i designed a page where you can schedule your travel and not only add some favorites. At the top we can find a map that show all the stops during the travel.

During this challenge I learned to iterate different options and be innovative.
The key is to target the good question to find the good answers. It’s it’s not so easy.
