Variance and trend analysis
“Variance and Trend Analysis” is a tool/technique for the process “Control Risks”.
Many control processes employ variance analysis to compare the planned results to the actual results. For the purposes of controlling risks, trends in the project?s execution should be reviewed using performance information.
Earned value analysis and other methods of project variance and trend analysis may be used for monitoring overall project performance. Outcomes from these analyses may forecast potential deviation of the project at completion from cost and schedule targets. Deviation from the baseline plan may indicate the potential impact of threats or opportunities.
