## 🎬 Conduct Usability Testing
> Usability tests are great when we need to understand **how the users interact with our product**.

## The Take Away
### Problem Statement
SNCF is the French national railway company responsible for the operation of the country's rail transport. Since 2017, tickets from several companies have been available on their digital travel platform. **How do consumers identify during the purchase, whether it is an SNCF journey or another company?**

### Solution
A **Report** that summaries the findings and recommendations for improvements.

### Roles
We conducted several **usability tests with eye tracking** to see how users navigate through the digital travel platform, then identified areas for improvement and made recommendations for changes.

## An Effective Usability Evaluation
### Determining usabilities issues
Thibault and Léa began to evaluate the design of the platform and **identified usability problems**. They went through the homepage and searched for any violation of Nielsen's 10 **Usability Heuristics**.
By looking for violations of these principles, Thibault and Léa were able to identify specific areas of the design that could be improved in order to enhance the user experience.

In complement, I used the **cognitive walkthrough** method to evaluate the usability of the **platform's search function** for finding train trips in Normandy. I, as a representative user, performed the task of searching for a train trip while noting any difficulties or confusion that arose.

I created a [[mind map 🛤️]] that **visualized the different steps and actions** taken during the task, and any issues encountered during the process. This helped us to identify areas for improvement in the platform's search functionality.

The heuristic Evaluation and and Cognitive Walkthrough methods complemented each other. They revealed a wide range of **usability issues** and helped us to focus our attention on specific tasks that have been identified as **problem areas**.

### Preparing a Usability Test
Our usability issues was used to inform the design of usability testing.
Basically, we intended to run usability tests around the **problematic areas** that we detected to further investigate the issues that were identified there.
![[SNCF_ProblematicAreas 2.png]]
We focused on **specific tasks** to further investigate the problematic areas that were identified. Then, we prioritised these specific tasks based on their **relevance to the business objective**.
![[SNCF_SpecificTasks 4.png]]
We created a **test plan to structure our usability test** by adding the most critical tasks that will be performed, the objectives of the test, the scenarios in which the test will take place, and the participant answer for each task.
