Do disagreements about work improve team performance?
Within a team, questioning a protocol, a priority or a deadline is not the same as challenging a person. The managerial question is specific: should leaders encourage disagreements about work to improve performance, or focus primarily on how those disagreements are resolved?
What the literature establishes
Karen A. Jehn (1995, Administrative Science Quarterly) distinguishes relationship conflict from conflict about the substance of work and shows that their links with group functioning depend, among other things, on the nature of the task. In the groups studied, disagreements about work can offer benefits for non-routine tasks, without producing the same results for routine tasks. This distinction invites managers to examine what a disagreement helps address, rather than value confrontation indiscriminately.
A synthesis less favourable to conflict
Carsten K. W. De Dreu and Laurie R. Weingart (2003, Journal of Applied Psychology) provide an important corrective: their meta-analysis finds generally negative relationships between task conflict and performance, and between task conflict and team member satisfaction. The negative relationship with performance is weaker when task conflict and relationship conflict are less closely associated. Separating ideas from people therefore remains relevant, but this conceptual distinction does not guarantee that they remain separate in actual exchanges.
The premature conclusion
One might conclude that a high-performing team should avoid all disagreement; that would confuse the absence of conflict with decision quality. The opposite injunction, deliberately provoking more confrontation to improve performance, equally exceeds the available findings. The managerial challenge is instead to enable an objection to be examined without treating conflict intensity as a goal. (our executive and employee training programmes)
The limits of the evidence and current practice
These studies do not constitute a trial showing that deliberately increasing or reducing conflict improves performance. A negative association may also reflect work difficulties that fuel tensions, and conflict measures do not always reveal how an objection was resolved. Counting disagreements or asking employees whether they can challenge one another is therefore insufficient to assess the quality of decision-making.
A practical check in Basel
As part of SHR's « Performance d'équipe » programme, a proposed exercise in Basel is to track, over two weeks, objections raised during decisions involving pharma, life sciences, Rhine logistics and international R&D. For each objection, record the disputed point, the evidence requested, the person responsible for responding and the final decision. Then calculate the proportion of objections that received a documented response before the decision was implemented, using the register and meeting records. This indicator measures the traceability of how disagreements are handled, not their causal effect on performance; it does not replace applicable quality and safety procedures.
