This article describes the findings of an exploratory case study into the requirements
management and engineering processes of a South African Systems Engineering Company and how
these processes affect the business of the company. For the purpose of this article the name of the
company is kept confidential. This case study identifies processes that resulted in both successful and
unsuccessful project performance, reasons for the problems, successful processes and ideas for
practice improvement. The findings illustrate which processes are used, why requirement processes
are important, and provide useful insights on causes of project failure and situations to be avoided.
The findings also show where the main focus for company improvement should lie. This case study
culminates in recommendations on ways to improve the current requirements processes of the
company and proposes a theory on the use of requirements management and requirements
engineering processes in the company.
