The present invention provides a method to support the coordination of geographically distributed activities, e.g. printing and, in particular, a method for mixed human and computer-supported distributed scheduling of a task according to scheduling decisions within a plurality of workplaces. The workplaces are connected to each other and to a shared negotiation facility via a computer network. The method involves expressing a first scheduling decision by manual modification in a scheduling board within a first of said workplaces, recording said first scheduling decision and creating computer-readable first scheduling decision data. These first scheduling decision data are transferred via the computer network to the shared negotiation facility, where said task is negotiated by combining the first scheduling decision data with second scheduling decision data received from at least a second of said workplaces. Negotiation results are transferred to at least said first workplace.
