Greve and Ejersbo (2005: 265–266) discuss notions of partnership. First, partnerships are to some extent dependent on the structure of the markets and partnerships need secure and stable conditions to thrive. Second, partnerships need time to build. Establishing trust-based relationships requires contractual negotiations where the partners get to know each other and their different views. Third, partnerships can be interrupted by external forces while partnerships are built and nurtured. (also Majamaa 2004; Pihkala et al. 2005: 242; Karisto & Lohivesi 2007: 30–31.)
