Social media technology has enabled virtual collaborative environments such that people can actively interact, share knowledge, coordinate activities, solve problems and co-create value. Organizations have begun to leverage approaches and technologies to involve numerous people from outside their boundaries to perform organizational tasks. Crowdsourcing is a collaboration model enabled by people-centric web technologies to solve individual, organizational, and societal problems using a dynamically formed crowd of people who respond to an open call for participation. Despite the success and popularity of this phenomenon, there appears to be a lack of guidance on how to organize the ideation processes in crowdsourcing. To address this need, we propose a Crowdsourcing Ideation Maturity Assessment Model (CIMAM). The CIMAM is intended to be sufficiently generic to be applied to different types of crowdsourcing initiatives/projects. It can be used by external assessors or by crowdsourcing organizers themselves for self-assessments. CIMAM was developed through a literature review and built on the constructs of Pedersen et al.  model. This paper contributes to research by examining the various factors influencing crowd engagement and productivity.
