Managing any socially innovative company seems very difficult. All the regular management functions seem undermined by a changed distribution of power. We should speak rather of governance than of management. However, to be able to govern effectively, we should be able to educate the future and present leaders of socially innovative companies. This requires appropriate tools. As was stated by Glaser (1966) guru of instructional science, to develop an educational program, you have to know what you want your learners to know and what they already know. To meet that goal we should measure the management knowledge of co-operators. Unfortunately, management is not biochemistry or software engineering, where it can be strictly defined. It has more tacit character. Wagner and Sternberg (1991; Sternberg et al., 2000) proposed a tool and a procedure to develop such tools including Tacit Knowledge Inventory for Managers (TKIM). If developed for co-operatives, such tools might measure tacit knowledge and have unprecedented influence on development and recruitment of future co-operative or other social enterprise leaders. In this paper, I describe the process of development of a tool measuring tacit knowledge of co-operators, that is persons for whom a co-operative plays an important role in their lives. They are aware of a co-op's specific values and principles and are actively involved in their co-operative's functioning, regardless of their position.
From the experts’ maps, I have elicited three main domains: (1) Values and needs domain, (2) Co-operative cohesion domain, (3) Co-operative management process. With the help of two practitioners, I wrote the case study stories with 10 possible solutions for each story. I sent this tool to 7 successful and highly appreciated practitioners from three countries. On the basis of agreement in the answers of the experts I have selected 10 case studies and created a key with which other participants can compare. This paper presents the first pilot results of testing the tool on a group of 29 persons, mainly from socially innovative companies.
