Purpose -This paper aims to recount the genesis of a successful innovation cluster among Irish-based divisions of multinational enterprises (MNEs) and Irish universities in the pharmaceutical industry. This cluster was actively "narrativized" through the language of obligation, desire, competence and know-how. As such, it is typical of the "hero's quest" literary genre in which challenges are faced, obstacles are overcome and victory is ultimately won. Importantly, in this story, the cluster was morally and pragmatically charged with dealing with significant challenges faced by the Irish pharmaceutical industry. Broader societal discourses operated as a resource for actors to use in proposing collaboration and innovation as the appropriate response to such challenges. Specifically, through narrative and discourse, actors created the necessary conditions conducive for a cluster to develop. These created a discursively constituted shared purpose which ultimately ensured successful innovation collaboration. Essentially, through narrative and discourse, the key actors identified the collaboration a protagonist in pursuit of a quest. By linking theoretical and empirical insights, the paper offers a conceptual framework that can be used in future studies to understand the emergence of clusters. Design/methodology/approach -Adopting Wengraf's (2001) structured approach to narrative interviewing, 18 key actors shared their understanding of how the cluster came into being. Each interview began with a single question intended to induce narrative, in this case "tell me the story of the cluster as you see it." This allowed participants to be in control of their own story (Wengraf, 2001). Each interview was transcribed in full and appended to notes taken at the time of the interview. Each narrative offered a "purposeful account" (Jovchelovitch and Bauer, 2000) of how and why the cluster was formed and the centrality of the participants' roles. In line with recognised protocols, in the authors analysis of data, they paid specific attention to how stories were told, the roles assigned to key protagonists, as well as how events and actors were linked in stories (see Czarniawska, 1997). Findings -This paper further demonstrates how language, metaphor and narrative and discourse (Hatch, 1997) becomes a strategic resource on which actors can draw to create desired realities (Hardy et al., 2000) particularly in terms of collaboration and innovation. Further, this case highlights how dialogue was encouraged throughout the process of establishing the cluster and has continued to be an important element. Rather than imposing some grand design, the SSPC cluster is and always will be emergent. In this sense, in the early stages of collaboration, detecting and supporting existing and emergent communities is essential to success, and shared identity which is the outcome of members' discursive practices appears to be a powerful driver of collaboration.
