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.

Opportunity spaces in innovation / Laura J. Kornish in Management science, Vol. 57 N° 1 (Janvier 2011)  

Public ISBD [article]  inManagement science > Vol. 57 N° 1 (Janvier 2011) . - pp. 107-128 Titre : Opportunity spaces in innovation : Empirical analysis of large samples of ideas Type de document : texte imprimé Auteurs : Laura J. Kornish, Auteur ; Karl T. Ulrich, Auteur Année de publication : 2011 Article en page(s) : pp. 107-128 Note générale : Management Langues : Anglais (eng) Mots-clés : Search Opportunity Opportunities Idea Ideation generation Innovation Creativity process identification Concept development Product design Entrepreneurship Index. décimale : 658 Organisation des entreprises. Techniques du commerce Résumé : A common approach to innovation, parallel search, is to identify a large number of opportunities and then to select a subset for further development, with just a few coming to fruition. One potential weakness with parallel search is that it permits repetition. The same, or a similar, idea might be generated multiple times, because parallel exploration processes typically operate without information about the ideas that have already been identified. In this paper we analyze repetition in five data sets comprising 1,368 opportunities and use that analysis to address three questions: (1) When a large number of efforts to generate ideas are conducted in parallel, how likely are the resulting ideas to be redundant? (2) How large are the opportunity spaces? (3) Are the unique ideas more valuable than those similar to many others? The answer to the first question is that although there is clearly some redundancy in the ideas generated by aggregating parallel efforts, this redundancy is quite small in absolute terms in our data, even for a narrowly defined domain. For the second question, we propose a method to extrapolate how many unique ideas would result from an unbounded effort by an unlimited number of comparable idea generators. Applying that method, and for the settings we study, the estimated total number of unique ideas is about one thousand for the most narrowly defined domain and greater than two thousand for the more broadly defined domains. On the third question, we find a positive relationship between the number of similar ideas and idea value: the ideas that are least similar to others are not generally the most valuable ones.
