What is it about?
This article shows how exploring potential conflicts between requirements can anticipate development complexity. It showcases with the differences between the initial concept for the Space Shuttle, what the Space Shuttle had to become to guarantee its funding, and the Soyuz spacecraft.

Why is it important?
It is too often that the development of systems is pursued without challenging decisions that have been taken at higher level of abstraction. However, these decisions result, more often than desired, in unnecessary conflicts that significantly increase the development complexity of such systems. This paper sets a path to promote the development of methods and approaches that enable identifying conflicting requirements or objectives early in a system's development.
Perspectives
Something I like about this article is how a simple method with notional data, i.e. low confidence, can still replicate some of the decisions that were taken when developing the space shuttle.
