If users can't find what they are looking for or get confused trying to buy from your site, you lose customers. If your web-based application is difficult to use, you lose productivity. To make sure that doesn't happen, 4Di applies rigorous usability standards and best practices across our design and development process.

Our requirements gathering method defines high level functional and cognitive needs of end users. Then we dig deeper to reveal the details of how users expect these features to work and what is motivating them to begin with. Defining these detailed requirements early in the project life cycle enables us to develop highly usable solutions on a fast track schedule.

Throughout our design and development process we rely on iterative prototyping and user feedback sessions. These help us further refine the user requirements and enable us to test proposed solutions BEFORE spending the time and money to develop them.

4Di offers a full range of stand-alone user input and testing services designed to analyze specific problem areas, identify solutions, and specify the best approach for new applications or web sites.
