Long partnerships, small circles
Which organisations have worked with the same few partners for fifteen years or more?
The organisations with the widest reach are not the only ones worth looking at. These have almost no partners at all — five or fewer — and have been working with one of them for fifteen years or longer.
What this list does and does not tell you. The number of years is the span between the first and the last project two organisations shared, measured by the project start dates. Eighteen years means the first and last project they shared began eighteen years apart; it does not mean they worked together without a break. Only organisations with five or fewer regular partners are listed, so the large institutes are absent by design rather than by accident.
