Enhancement Activity Ratios

Although data in this chart comes from the Development & Enhancement repository, it is useful because in some organisations' maintenance staff undertake significant enhancements.  This chart shows the percentages of the total enhancement project time spent on the six activity types.  Use the ratios shown in this chart to more accurately estimate effort for a large enhancement project that requires a formal development approach, and to monitor and recalibrate likely effort during an enhancement project.
