Idea generation and the quality of the best idea / Karan Girotra in Management science, Vol. 56 N° 4 (Avril 2010)

Techniques du commerce Résumé : In a wide variety of settings, organizations generate a number of possible solutions to a problem—ideas—and then select a few for further development. We examine the effectiveness of two group structures for such tasks—the team structure, in which the group works together in time and space, and the hybrid structure, in which individuals first work independently and then work together. We define the performance of a group as the quality of the best ideas identified. Prior research has defined performance as the average quality of ideas or the number of ideas generated, ignoring what most organizations seek, a few great ideas. We build a theory that relates organizational phenomena to four different variables that govern the quality of the best ideas identified: (1) the average quality of ideas generated, (2) the number of ideas generated, (3) the variance in the quality of ideas generated, and (4) the ability of the group to discern the quality of the ideas. We test this theory with an experiment. We find that groups organized in the hybrid structure are able to generate more ideas, to generate better ideas, and to better discern the quality of the ideas they generate. Moreover, we find that the frequently recommended brainstorming technique of building on others' ideas is counterproductive; teams exhibiting such buildup neither create more ideas, nor are the ideas that build on previous ideas better.

The Relational advantages of intermediation / Elena Belavina in Management science, Vol 58 N°9 (Septembre 2012) 

Public ISBD [article]  in Management science > Vol 58 N°9 (Septembre 2012) . - pp.1614-1631 Titre : The Relational advantages of intermediation Type de document : texte imprimé Auteurs : Elena Belavina, Auteur ; Karan Girotra, Auteur Année de publication : 2012 Article en page(s) : pp.1614-1631 Note générale : Management Langues : Anglais (eng) Mots-clés : Global  sourcing  Intermediaries  Supply  chain  relationships  Relational  contracts  Flexibility  Li  &  Fung  Repeated  games Résumé : This paper provides a novel explanation for the use of supply chain intermediaries. We find that even in the absence of the well-known transactional and informational advantages of mediation, intermediaries improve supply chain performance. In particular, intermediaries facilitate responsive adaptation of the buyers' supplier base to their changing needs while simultaneously ensuring that suppliers behave as if they had long-term sourcing commitments from buying firms. In the face of changing buyer needs, an intermediary that sources on behalf of multiple buyers can responsively change the composition of future business committed to a supplier such that a sufficient level of business comes from the buyer(s) that most prefer this supplier. On the other hand, direct buyers that source only for themselves must provide all their committed business to a supplier from their own sourcing needs, even if they no longer prefer this supplier. Unlike existing theories of intermediation, our theory better explains the observed phenomenon that although transactional barriers and information asymmetries have steadily decreased, the use of intermediaries has soared, even among large companies such as Walmart.
