What is it about?
This paper reports the results of a factorial experiment with systems engineering practitioners that measures the effectiveness to elicit less unnecessary and inapplicable (excess) requirements, given a problem statement. In essence, it tests the effectiveness in practiced of our Max-Neef categorization of requirements.

Why is it important?
The experiment shows that the Max-Neef inspired categorization seamlessly improve requirement elicitation practice in terms of eliciting less excess requirements. This has a direct impact on the cost associated to requirements and on avoiding over-constraining requirements. Furthermore, it puts down to test for the first time in a rigorous manner the effectiveness of a categorization of requirements, thus going beyond relying on lessons learnt, best practices, or subjective opinions.
Perspectives
A key element of this paper is that it tests the actual potential of a method with practitioners. It therefore goes beyond its theoretical effectiveness, recognizing that the eventual effectiveness depends on how practitioners will use the method. And notwithstanding that in the real-world companies may not be able to execute big training investments, testing how seamlessly a method can improve practice can be very valuable for an organization.
