Integrated product architecture and pricing for managing sequential innovation / Vish Krishnan in Management science, Vol. 57 N° 11 (Novembre 2011)

Techniques du commerce Résumé : Science and technology advances drive firms to continually enhance their product's performance and launch sequentially improving offerings. Firms face challenges in marketing such improving products to well-informed, forward-looking consumers who anticipate product improvements and seek to delay their purchase timing. Product design, specifically a modular upgradable architecture in which improving and stable subsystems of a product are separated and selectively upgraded, can be a valuable approach for marketers to alleviate consumer concerns about product obsolescence. However, such an architecture-based approach can present new challenges as well, and dealing with them requires carefully coordinated cross-functional decision making by the firm. In this paper, we identify and formalize the notion of design inconsistency, which refers to the monopolist firm's inability to commit to future product design architectures. We find that firms experience design inconsistency even when they are able to commit to future prices, and design inconsistency lowers firm profits as well as consumer surplus. We then derive a joint product architecture and pricing approach to solve this problem; this enables an innovating firm to optimally and in a time-consistent manner launch modular upgradable products. The modeling and analysis in the paper lends insight into types of markets and products for which modular upgradability is most appropriate and offers guidelines on making pricing and product design decisions jointly for managing sequential innovation.

Managing delegated search over design spaces / Sanjiv Erat in Management science, Vol. 58 N° 3 (Mars 2012) 

Public ISBD [article]  in Management science > Vol. 58 N° 3 (Mars 2012) . - pp. 606-623 Titre : Managing delegated search over design spaces Type de document : texte imprimé Auteurs : Sanjiv Erat, Auteur ; Vish Krishnan, Auteur Année de publication : 2012 Article en page(s) : pp. 606-623 Note générale : Management Langues : Anglais (eng) Mots-clés : Research  and  development  Open  innovation  Product  design  Clustering  Search Résumé : Organizations increasingly seek solutions to their open-ended design problems by employing a contest approach in which search over a solution space is delegated to outside agents. We study this new class of problems, which are costly to specify, pose credibility issues for the focal firm, and require finely tuned awards for meeting the firm's needs. Through an analytical model, we examine the relationship between problem specification, award structure, and breadth of solution space searched by outside agents toward characterizing how a firm should effectively manage such open-ended design contests. Our results independently establish and offer a causal explanation for an interesting phenomenon observed in design contests—clustering of searchers in specific regions of the solution space. The analysis also yields a cautionary finding—although the breadth of search increases with number of searchers, the relationship is strongly sublinear (logarithmic). Finally, from the practical perspective of managing the delegated search process, our results offer rules of thumb on how many and what size awards should be offered, as well as the extent to which firms should undertake problem specification, contingent on the nature (open-endedness and uncertainty) of the design problem solution being delegated to outside agents.
