product refinement and improvement by interaction design

This portfolio represents an interactive design backlog. This document is for a product that was launched and had more than hundreds of thousands of users.
 

The analysis of this digital product, according to the principles of interactive design, helped a lot in designing a useful and practical experience for the user.

Methods and steps

The usability analysis of the system was presented using both quantitative and qualitative methods. The analysis was based on five layers of interaction design. The review included surveys, analysis of users' opinions and questions, assessment of users' attitudes (what do they say?), and analysis of Google Analytics criteria such as defining goals and the average time of user interactions with the system. The behaviour of users (what do they do?) was also analyzed.

Here are the steps involved in the project:
Surveying the integrated car allocation system users;

  • The survey participants were divided into three groups: main winners, reserve winners, and non-winners in the lottery. We selected 2000 users from each group, and in total, we sent the questionnaire link to 6000 people.

  • The survey comprised two parts: satisfaction measurement and usability measurement. We based the questionnaires on two metrics: System Usability Scale (SUS) for measuring usability and Customer Satisfaction Score (CSAT) for measuring user satisfaction.

The call centre frequently receives questions from users, which are then reviewed and analyzed to improve user experience. The analysis is based on five layers of interactive design and aims to extract the user's path to solve their needs in the system.

​

Similarly, users' opinions on social media and news sites are analyzed using the same five layers of interaction design to understand their needs and improve the system accordingly. In addition, a report from the Google Analytics platform provides insights into user behaviour, including their path from registration to product selection, device statistics, and other relevant information.

Survey questions

  • Was the process of creating the user account complicated?

  • I think most people will quickly learn how to use the system.

  • I spent much time finding the related service.

  • I could not find the object I wanted.

  • It was hard to give up the chosen object.

  • The guide for using the system was straightforward and practical.

  • Accessing the user panel was easy.

  • The texts of the system were difficult to see and read

Visual analyzing

  • The second layer of interaction design involves visual cues, including graphic elements, images, typography, and icons that users interact with. To assess the usability of the system in terms of visual elements, a question was posed: "Were the texts of the system difficult to see and read?" Based on the user's response, the score for this question was 4 out of 29.

  • To ensure that the system is accessible to users with different visual impairments, a questionnaire and survey were conducted. Additionally, the system is based on the standard (WCAG), which is a global accessibility standard that has been reviewed and analyzed.

  • To provide insight into the system from the perspective of users with different visual impairments, images were included below...
