What is it about?
This paper presents a new method to support early identification of conflicting requirements. It provides higher effectiveness than simply relying on subject matter experts, while requiring a significant lower effort than parametric system modeling. Furthermore, in contrast with other existing approaches, the proposed tension matrix does not use pairwise comparisons between requirements, but assesses the requirement set as a whole in order to avoid fundamental flaws in the exploration effort.

Why is it important?
Identifying and removing unnecessary conflicting requirements is key to ensure a design space that contains affordable solutions. Unfortunately, existing methods either require a high upfront effort investment or they are fundamentally flawed, since by being built on pair-wise comparison approaches, they are only able to identify a minimum subset of potential conflicts. This paper presents a method that overcomes those problems, thus contributing to improve early identification of conflicting requirements.
