Performance reports summarize project activity progression by comparing your project's performance to its schedule baseline.
Performance reports come in many shapes and sizes. From a time management perspective, the obvious reporting format to use is a graphical representation of project performance. The four most frequently used graphical performance reporting formats are the: Gantt chart, S-curve, histogram, and table.
- Gantt chart - A Gantt chart displays schedule-related data. The dates are shown across the top of the chart to illustrate the time line.
- S-curve - An S-curve displays cumulative costs, labor hours, or other quantities plotted against time.
- Histogram - A histogram is a bar graph of a frequency distribution. The bar width represents the division of each variable into task duration. The height is relative to the number of resources required.
- Table - A table displays semi-processed numerical data for a minimum of two variables. Data is relevant to an individual project's needs.
A reliable reporting system helps to ensure that projects progress according to plan. It can help determine when corrective action is necessary. The reporting system provides:
- regular, accurate status updates
- concise, easily understandable information
- potential problem forecasts.
Current reports
Current reports document progress solely on those activities scheduled for work during the reporting period. Reports show activity highlights and any variances from a project's plan. Follow-up on current reports should provide project details, including reasons for variances and a recommended corrective action plan.
Cumulative reports
Cumulative reports examine the project's history—from start-up to the end of the current reporting period. Cumulative reports display trends in project activities that, over several periods may exhibit improvements or chronic problems.
Exception reports
Exception reports are high-level summary reports submitted to senior management. Sometimes these reports are followed by an additional report if more detail is required.
Green-yellow-red reports
Green, yellow, and red reports are very simplified versions of performance reports. These reports get the intended point across with a minimum amount of reading required.
- Green reports - Say that everything is going according to project's plan.
- Yellow reports - reveal a schedule slippage with a corrective action plan.
- Red reports - indicate a project is out of control with no action plan in place.
Comparing project performance to the schedule baseline will be easier once your company selects the most appropriate performance reporting format and method of presentation to meet its needs.
