The Importance of Ontological Commitment and Linguistics in Relation to the Elucidation of Design Requirements

Abstract

One of the design process’s earliest and most critical stages is establishing and determining requirements. Design requirements are often expressed through language, whether in written documents, diagrams, or verbal discussions in terms of the client’s “wants” and “needs” or balancing what they can “afford.” Designers use of quotes around “wants,” “needs,” and “afford” signals ambiguity or doubt in the meaning of the terms. The language used during early discourse is crucial for expressing and translating these
ambiguous terms into specific unambiguous design requirements, which significantly shape and constrain possible solutions. In philosophy, this concept is known as ontological commitment. Embedded language in requirements documents, expressed through constraints, objectives, and functions, establish the ontological commitment to a specific solution space. Prior marine design research has focused on the wicked problem of requirements elucidation, with the goal visualizing potential solutions derived from language, and a more direct link to ontological commitment was developed by Andrews in the concept of style Duchateau (2016) van Ores (2011) Andrews (2012). However, the role and impact of linguistics in translating and interpreting uncertain or ambiguous terms into specific design requirements has been largely overlooked. This paper presents modern direct examples of ontological commitment from requirements development for the Littoral Combat Ship.
