In the first phase, emineo obtained an overview of the valuation of non-listed companies in order to be able to form a competent project team. Without a comprehensive professional and technical understanding, it would not have been possible to discuss at eye level with the experts of the STC and to make sound suggestions to them for the correct functionality of BVTax. The next step was to define the processes, the roles and the information architecture. Finally, it was about implementing the system architecture, the use cases, the user interface and the calculation engine. The main technical challenge was to embed BVTax in a complex system network with many other solutions and stakeholders.
A key element of the agile and iterative collaboration between STC and emineo were the weekly workshops. In each of these workshops, emineo presented prototypes for different use cases. These were then discussed and refined in the group and formed the basis for the development of BVTax.
