In Genève, is bringing together the best enough to build a high-performing team?

In Genève, private banking, international organisations, luxury watchmaking and commodity trading rely on specialists whose expertise is an essential resource. The management question is not whether to recruit capable people, but whether adding another recognised expert still improves performance when individual contributions are closely interdependent.

What the literature establishes

Roderick I. Swaab, Michael Schaerer, Eric M. Anicich, Richard Ronay and Adam D. Galinsky (2014, Psychological Science) show, in their analyses of sports teams, that the relationship between talent concentration and performance depends on task interdependence. In the sports studied where coordination matters, the benefits associated with talent can reverse when talent becomes highly concentrated. The same pattern does not appear in baseball, where contributions are more separable.

Status can complicate coordination

Boris Groysberg, Jeffrey T. Polzer and Hillary Anger Elfenbein (2011, Organization Science) examine groups of financial analysts and find that accumulating high-status members does not guarantee increasing collective effectiveness. Their findings highlight difficulties in integrating work when several people hold prominent positions. Status is not a pure measure of competence: this study illuminates a complementary mechanism rather than precisely replicating the previous one.

The premature conclusion

It would be a mistake to conclude that a team should limit its members’ competence. These studies examine how individual resources translate into collective results, not the value of expertise itself. For a manager, the question therefore becomes: does the new specialist provide a missing capability, and how will their contribution fit with those of others?

What the evidence cannot decide

These studies provide no universal ceiling on the number of talented or recognised individuals a team should contain. Their settings and measures also prevent direct transfer of their findings to a Genève team working in compliance, diplomacy or watch production. Field analyses remain vulnerable to selection effects: teams recruiting the most sought-after people also differ in resources and ambitions.

A practical check in Genève

Within SHR’s « Performance d’équipe » programme, a Genève team could test an explicit rule identifying who proposes, who contributes and who decides for one category of recurring cases, without changing team membership. Whether the work concerns a private banking case, an interinstitutional briefing, a watchmaking approval or a commodity transaction, the measure would be the proportion of cases reopened after approval because specialists’ assessments remain incompatible, calculated across all approved cases in that category. Comparing this measure before and during the trial, over periods of equal length and while documenting case complexity, would help assess an integration problem rather than attribute it solely to recruitment. A reduction would be a useful signal, not sufficient causal proof.
