This document discusses potential collaboration between organizations that received funding from the Big Lottery Fund BASIS Programme. It identifies 13 national bids that were submitted and looks for relationships between the bids in terms of either addressing generic national issues, having a geographic focus, or focusing on specific outcomes. Examples of collaborative actions are provided, such as one organization informing the curriculum of another's training program. Principles for collaboration are proposed, including initially identifying shared aims and outcomes and allowing flexibility in collaborative arrangements. Wider lessons discussed include the need for a common vision, focusing on overall outcomes, and funder support for ongoing collaboration.
