In the field of user-centered design of interactive systems, task models play a major role, especially in defining requirements, or during the system validation phase. They lean on precise semantics, based on a set of formal operators. In this article, we demonstrate how the addition of new description tools (pre-conditions, objects) introduced ambiguities in model interpretation, and we propose our solutions to solve this problem.
