Too Rigid with the Test Plan

An experienced test moderator will know when to deviate from the test plan. It is important for the moderator to sense when the test design is not achieving its objectives and is not exposing the product's deficiencies to the fullest extent. At tho^e times, it is up to the moderator to make the appropriate changes so that a participant's time and efforts are not wasted. Sometimes a participant with a different background than what was expected will appear. Sometimes the tasks are the wrong ones for addressing the research questions. Whatever the case, it is up to the moderator to revise the plan accordingly.
