Collaborated closely with cross-functional teams, including project managers, developers, and stakeholders, to ensure successful project delivery.

Common Review System

The Fund aimed to modernise its outdated eReview system for managing reviews. Because the application was unhandy, the goal was to create a more intuitive and personalised experience to improve user comfort and trust.

Usability Testing / Click testing

Example: 7 participants - played the role of the Author, Janice Mitchell. They were presented a Power Point Presentation in which we used the 10% (text) and 90% (image from our product) methodology. The users imagined that they were moving the cursor on the screen and pointing out by thinking out loud, were would they click, the reason why they did that action and what was their feeling completing a task. The session was moderated by facilitators, remote and lasted 45 minutes.

For this role, we tested how to Create Review, Prepare & Initiate Interdepartmental Review, Checking for comments from departments. After the test, the participants received a Word document for an over all usability of IMF product. This System Usability Scale (SUS) gave us a more comprehensive understanding of the user feedback by calculating a final score for each participant. This research report includes the details of how we conducted our research, the results we found, and a brief list of recommended changes.

Outcome

The redesigned system introduced a more structured review process, with stages clearly defined as Planned, Interdepartmental, and Clearance. This new system was a significant success, offering a more transparent, reliable, and user-friendly experience. The improved Common Review System helped the IMF build greater trust with users, leading to higher user satisfaction and confidence in the product.

Outcome

This proposed mobile MVP embodies the principles of clarity, transparency, usability, and fluidity in its design. By focusing on the examiner's needs and streamlining the grading process, we can enhance user experience significantly while maintaining the integrity and security of the examination process.
