Using Software Engineering (SE) knowledge to support the software development process is challenging due to the complex structure of SE knowledge and the uncertain nature of large-scale software projects. However, already before developing software, establishing a development process suitable for the project at hand is another challenge. This paper presents a Requirements Engineering (RE) tool that contains a knowledge base to support RE process development and selection of RE techniques. The tool is built based on the Framework for Requirements Engineering pRocess dEvelopment (FRERE). The major merits of the tool over others is that the tool uses knowledge representation to manage the knowledge of the RE process and its technique, thus assisting development of the most suitable RE process for a software project.
