Départements : Stratégie et Politique d’Entreprise


De plus en plus de business schools investissent massivement dans la communication et dans des politiques de marque. L’auteur de l’article, rattachant ce phénomène à la mondialisation du secteur, analyse les différents ressorts de ces politiques et montre, par ailleurs, qu’elles ont pour conséquence de créer des barrières à l’entrée, pour décourager les nouveaux entrants potentiels. Il insiste enfin sur l’imbrication entre la marque d’une école et l’image du pays dans lequel elle est implantée

We examine the accuracy of forecasts of the commercial potential of new product ideas by experts at an Inventor's Assistance Program (IAP). Each idea is evaluated in terms of 37 attributes or cues, which are subjectively rated and intuitively combined by an IAP expert to arrive at a forecast of the idea's commercialization prospects. Data regarding actual commercialization outcomes for 559 new product ideas were collected to examine the accuracy of the IAP forecasts. The intensive evaluation of each idea conducted by the IAP produces forecasts that accurately rank order the ideas in terms of their probability of commercialization. The focus of the evaluation process on case-specific evidence that distinguishes one idea from another, however, and the corresponding neglect of aggregate considerations such as the base rate (BR) and predictability of commercialization for new product ideas in general, yields forecasts that are systematically miscalibrated in terms of their correspondence to the actual probability of commercialization.

We study the effects of organizational code-preserving and code-violating changes on externalevaluations by third parties'an essential but under-studied strategic outcome. We define codepreservingchanges as a variation in the firm's product range that preserves the social codewithin which the firm positions its offering. By contrast, a code-violating change correspondsto a variation in the product range that breaks with past codes and embraces another socialcode. Our analyses of French haute cuisine restaurants show that code-preserving changes andcode-violating changes have positive effects on external evaluations. Both effects decline withprior evaluations received by the organization, but only the effect of code-violating changesis reduced with age. Moreover, external evaluations improve when restaurants undertake morecode-preserving changes than their direct competitors but decline when they make more codeviolatingchanges than competitors. These results enable us to derive implications for researchon strategic change, strategic groups, and strategic social positioning.
