Conflict and Strategic Choice: How Top Management Teams Disagree
Abstract
Substantive conflict is natural within top management teams as executives struggle with making high-stakes choices under conditions of ambiguity and uncertainty. Yet, many top management teams fail to sufficiently debate appropriate courses of action. This article reports on a field study of top management teams and examines four managerial levers that can help executives overcome the cognitive, emotional, and political barriers to engaging in conflict. These levers are: build a heterogeneous team; create frequent interactions within that team; cultivate a distinct symphony of roles such as Counselor, Futurist, and Ms. Action around fundamental tensions within managing; and use multiple-lens tactics such as competitor role playing and multiple alternatives to provide unexpected vantage points on key issues.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
