Advancing A Typology Of Open Innovation

Interest in the concept of open innovation (OI) has increased during recent years; yet, this line of inquiry remains limited due to the lack of a more comprehensive conceptual framework. As a first step toward a unifying framework, we provide a critical review of previous research on the conceptualization, antecedents, and consequences of OI. We then offer a typology describing four OI strategies: (i) innovation seeker, (ii) innovation provider, (iii) intermediary, and (iv) open innovator, which emerge through unique combinations of sources of innovation, firm attributes, and mechanisms of inter-organizational exchange, and produce varying outcomes. Finally, we discuss our typologys implications for theory and practice, and advance potential research avenues.

A supplier development adoption framework using expectancy theory

Purpose – The purpose of this paper is to apply expectancy theory to advance a conceptual framework which identifies factors that motivate and affect the adoption of supplier development (SD) activities. Design/methodology/approach – The authors conduct a comprehensive literature review to identify salient contributions and conceptual gaps within prior SD studies. These conceptual gaps motivate the use of expectancy theory and the broader management literature to develop a conceptual framework of SD adoption. Findings – The study results in the development of a two-stage conceptual framework in which two behavioral constructs – SD expectancy and valence – play an important role in mediating the effects of activity-, firm-, interfirm-, and environment-level factors on the adoption of SD activities. Accordingly, the authors advance 11 testable propositions that underlie the logical development of the framework. Research limitations/implications – The application of expectancy theory facilitates the integrat...
