Question Set & Coverage: What impact does using a reduced question set have?

Our scientifically validated teamecho Insights question set consists of 66 questions across 10 categories.

If this set is reduced, certain questions may be repeated more frequently. While this creates stability around those specific topics, it also carries the risk of creating blind spots. A stable score then simply indicates that things are running smoothly in the areas currently being surveyed—but it tells you nothing about the categories left unused.
