In this paper we examine which type of alliance experience matters most for developing an alliance management capability. Although experience is deemed to be an important antecedent of a firm’s capability to manage collaborations, we argue that only some types of alliances are likely to foster the development of such a capability, thus representing the valuable alliance experience. Starting from the identification of the constitutive skills of an alliance management capability, we develop a theoretical framework which proposes that only alliances resembling the nature of the so-called embedded ties provide firms with these specific skills. We refer to the collection of such alliances as a firm’s repertory of embedded alliances. Moreover, we argue that, in order to affect the capability building process, such a repertory needs to be not only extensive but also heterogeneous in terms of alliance goals, contents, governance forms and partners. Finally, we assume a stronger effect of the valuable alliance experience when leveraged through the use of deliberate learning mechanisms.
