How can you improve collaboration at work when people have different priorities, responsibilities and levels of authority? This practical guide helps you diagnose how people are currently working together, understand what a particular task or relationship requires and identify what may be preventing progress. It introduces the 6 Cs of collaboration: coercion, confrontation, coexistence, cooperation, collaboration and co-ownership. You will learn how to recognise each way of working, decide how much collaboration is actually needed and address the behavioural, relational and organisational conditions affecting the relationship. Rather than assuming every situation needs greater shared ownership, the framework helps leaders make deliberate changes that strengthen cooperation, joint problem-solving, decision-making and accountability across teams and organisational boundaries.
