Following concept approval, umwerk will start the software visualization phase, replacing the traditional time-consuming and costly requirement documentation, and providing a much better understanding of the project’s user experience, processes, and functions. By means of the visualization techniques we use, we will create a functional prototype tailor-made for the respective project. This Proof of Concept (POC) is a “real” application with a limited amount of functionalities and data that our clients’ users may test in their real-life environment. Feedback and changes are incorporated directly into the POC. As a visual requirement document, the POC will do away with uncertainties in terms of project needs, by solving unforeseen issues and thus reducing potential risks.
