By definition, working with others means dealing with different forms of knowledge, expertise, experiences, cultures, preferences, values and norms. These differences often lead to confusion in speech and a lack of clarity. A common way of approaching collaboration can help to reduce speech confusion. We develop approaches, methods and tools with which partners can look at their collaboration in a shared manner. It is therefore no coincidence that one of our earlier publications on collaboration was entitled A new looking glass for a clear view of collaboration (in Holland Management Review, by Robin Bremekamp, Edwin Kaats and Wilfrid Opheij, 2009).
