Graphical User Interface Prototyping for Distributed Requirements Engineering


Sven Scheibmayr

Finding and understanding the right requirements is essential for every software project. This book deals with the challenge to improve requirements engineering in distributed software projects. The use of graphical user interface (GUI) prototypes can help stakeholders in such projects to elicit and specify high quality requirements. The research objective of this study is to develop a method and a software artifact to support the activities in the early requirements engineering phase in order to overcome some of the difficulties and improve the quality of the requirements, which should eventually lead to better software products. Therefore, this study seeks to support the work with these prototypes in distributed projects. It is based on a theoretical analysis and follows a design science research approach.

7. Summary and Outlook


In the first section of this chapter, the results of this thesis are summarized. The second section provides an outlook and suggests possibilities for future research.

7.1. Summary

This thesis follows a design science approach (see Section 2.4) and reports the design and evaluation of a method and tool, which support stakeholders in distributed software development projects to work in collaboration on GUI prototypes. The prototypes act as boundary objects and stimulate the creation of design ideas, visualize possible solutions, transfer knowledge between stakeholders, help to create a shared mental model of requirements, and validate those requirements.
