In order to create a successful socially useful software it is necessary to invest a lot of effort. It is important to manage the development team and their interpersonal relationships from the very beginning. The software manager must have different skills for the software development to reach a satisfactory level. He has to prove his ability to lead people and manage both the project and the clients. The most important part of the software development is for it to be well accepted, hence the testing which allows to see how to product is perceived. Thus, testing is the best way of avoiding the risk of failure in the first phase of entering the market. The second thing to point out is communication. The software manager has the very important responsibility of clearly end thoroughly explaining each task and requirement. He also has to understand the client's wishes (requirements) and communicate them to the team. The communication between the team and the software manager must always occur in an appropriate language, which consists of well-structured task and requirement description with diagrams in order to avoid potential mishappenings or misunderstandings. In this thesis, the project approach has been presented with a creation of an hypothetic web and mobile software which is meant to offer a clear view of all discounted items in the customer's surrounding area. A detailed scenario of the usage of the software wireframe for both web and mobile channel and client user interface was created for this occasion. Part of the research and testing was a 24 question questionnaire, which was important for understanding the target audience and their habits. The project was established after the first ideas and pitching the software's concept. From this point on, the thesis was written in a project-based approach. Finally, this can be perceived as a small part of a potential documentation for a further and more detailed project, in which case this part should be revised and enlarged with real facts, workflows, timelines and deadlines.
