Description:
Capturing and managing requirements are crucial to the success of product design and development. This paper presents and analyzes the causes of requirements change during the design process of a complex aerospace system developed by Rolls-Royce during the course of 6 years. The study was part of a series of efforts ongoing at this original equipment manufacturer to improve requirements engineering practices and involved a group of engineers in the assessment of the root causes of change. A large data set was examined, containing 700 system requirements and more than 1,000 changes released during the project studied. The results showed that more than 80 % of the changes had internal root causes and change driven by the customer accounted for about 15 % of the total. The structured approach that was implemented to understand the causes of change allowed the group of engineers to identify and dissect various management guidelines aiming to further improve requirements engineering in practice. This paper thus also reports the guidelines captured at this aerospace manufacturer and intends to support practitioners across the industrial community.
