Different organisations can come together behind a shared purpose, and set up a joint steering or governance group, to direct it in a form of collective leadership. We see this for networks, joint programmes or even the multi-stakeholder governance of an organisation of central interest to all. We have also repeatedly observed how such collective leadership can be profoundly disrupted by behaviour of some of its members, who prioritise their own organisational interests, want to impose their own choice against the majority decision, and may become disrespectful to those with a different view. Even collective leadership groups who have formalised most of their functioning tend to struggle with such situation, as they have not rendered explicit fundamental behavioural expectations of members of a collective leadership group. Our advice: make them explicit. See our 2 pager for more detail here.
