Understanding airlines' value perceptions for value-based requirements engineering of commercial aircraft

Abstract

Although Systems Engineering (SE) processes and standards are widely used in aircraft development programs, traditional requirements engineering practice for commercial aircraft does not explicitly address value perceptions and related, relevant information. In this paper, a novel approach is proposed to promote a better understanding of customer value perceptions for value-based requirements engineering. The approach is a four-step process leading from initial customer statements to component value models. A set of theories and methods is introduced in order to resolve the different concerns regarding the appropriate understanding of customer value perceptions, and based on these, the establishment of the requirements. A case study is used that shows the transformation of airlines’ initial expectation statements into a corresponding group value model, which supports the first two steps of the approach. The benefits of this approach are that perceived customer value can be explicitly qualified and quantified; and subsequently used reactively for design evaluation, and proactively for value-driven design.
