Sankey Diagram

A visual flow diagram which represents data as arrows and/or flow lines, with the width being proportional to the total value. This is one way of representing cost and staff input breakdowns in relation to a range of cost-centres or subject headings.

The Sankey diagram below provides a visual example of how a grounds operative's annual workdays might typically be apportioned, either as a forward planning tool or a reflective tool as part of a continuous improvement programme. The productive time and supporting times can be further divided to help identify specific areas that might be improved for efficiency and/or reallocated as required.
