Agile programming - Introduction and current legal challenges

Within the realms of software development, customers must specify the requirements of their new software before the start of the project. Today, this leads to considerable delays with respect to the start of the project. In addition, the integration of new requirements into a system already developed in parts is becoming increasingly time-consuming and cost-intensive. Yet the specifically necessitated functions of a software are often only revealed through the process of development. By means of agile programming, changes in the requirements of a software product can be handled flexibly in shorter development cycles. In the following, the framework of agile software development projects as it applies under German law is described and current legal problems of such projects - in particular, the issue of contract type and the new building contract law - are considered. The unplanned project design appears contrary to the legal approach. The article shows, however, that agile software products development provides customers with dynamic and quickly scalable products and that customers can leave the project after individual project steps. The new development of building contract law, which focuses on subunits and approvals, is also very much in line with the above-mentioned programming.
