Customer case study: Trade Interchange

Usability testing and advice alongside the last stages of the Trade Interchange agile development process, to maximise self-service for potential customers setting up and running trial versions of their suite of eSourcing applications.

" the tests have been very useful and your comments and feedback will help us build a product that is easier to use "

Mike Edmunds, CTO

Trade Interchange were preparing to introduce a new way of selling their suite of eSourcing applications - making a partially featured free version available to encourage evaluation. Their SIM - Supplier Information Management module was to be the first one available in this format, and as its release date approached, the team were thinking about what needed to be in place to ensure that the module supports self-service learning and troubleshooting. Ideally, users should be able to explore and use the application independently - reducing the support load for Trade Interchange.

How 3di Software Usability helped

We worked alongside the Trade Interchange development team in the last few iterations of their agile development process. We designed and ran remote usability tests to identify issues with core functionality by asking candidates to complete common tasks, and talk through their experiences. This feedback enabled us to both identify troublespots and get an understanding of the causes of the issues. It also enabled us to confirm areas of the UI that were working effectively.

Between tests the development team made changes to the application to address issues we'd highlighted, so that in the next tests the candidates wouldn't get stuck on the same issues.

Reports and results

The development team watched videos of each test, with the user's audio commentary, mouse clicks and keyboard input. We also created and updated a report at each phase of testing, logging:

  • prioritised list of usability issues
  • recommendations for addressing issues
  • recommendations for additional "help" information in the UI
  • running update on status of issues found in earlier tests


The iterative process of testing and implementing improvements meant that we could confirm that many usability issues were fixed before the application was released. The product is now on the market, successfully making use of a trial phase where potential users set up and run the product in order to evaluate its functionality.

Trade Interchange are implementing lessons learned from our usability tests in their other modules, and plan to make usability testing a stage in their regular UI development processes.
