In some embodiments, a method includes defining a sequence of process resources. Each of the process resources is for performing at least one respective task on a work item. The method further includes calculating a resource utilization metric for each of the process resources. The method also includes displaying a representation of at least a portion of the sequence of process resources. The representation includes image elements that each have a dimension that is inversely proportional to the resource utilization metric for the process resource represented by the image element in question.
