High market competitiveness and a lack of internal resources and knowledge make companies increasingly interested in open innovation, being the collaborative innovation projects with suppliers one of the most widely used initiatives. However, the collaborative process is difficult to manage given the diversity of factors to consider when mixing different organizational cultures, resources, competencies, and experiences. One way to support the process is through the management of related good practices. Therefore, based on a review of the literature and international standards on open innovation or collaboration, this document identifies five dimensions and 18 practices of the customer-supplier collaborative innovation process. The identification of these good practices allows the characterization of the customer/supplier collaboration process in innovation projects and allows the establishment of a reference framework for the creation of an evaluation model.
