In the validation of requirements with scenarios, a straightforward communication is central to obtain a good participation from stakeholders. Technical specifications are translated into scenarios to make them concrete and easy to understand for non-technical users, and contextual details are added to encourage user engagement. However, additional contextual details (Ahab's legs) could generate a negative impact on the requirements' validation by leading to proliferating comments that are not pertinent to session objective. The objective of this study is to evaluate the impact of Ahab's leg to scenario-based requirement validation sessions. We conducted a controlled experiment with human participants and measured the pertinence of the comments formulated by participants when discussing the requirements. The results of our experiment suggest that the potentially negative impact of Ahab's leg can be effectively controlled by the analyst.},

abstract = {To meet stakeholder non-technical background, requirements are often presented by analysts in terms of scenarios.

In the present paper, we address the Ahab's Leg dilemma and its potential impact on requirement validation sessions.

Moreover, we present the design of a controlled experiment devoted to measure the impact of Ahab's Legs on requirement validation sessions. In particular, the experiment is meant to (1) estimate the magnitude of the distracting effect, and to (2) assess one of the most promising way to alleviate their negative effect, i.e. by making stakeholder aware of the Ahab's Legs before the validation session.},
