Display Cumulative or Current Values
You can analyze either cumulative values or current (period-specific) values. Charts and tables that focus on one period display either cumulative cost/schedule variance values as of that period or the cost/schedule variance values for that period alone, depending on the option you select. Trending charts and tables show either the change in cumulative cost/schedule variance values from period to period or, if you select Current, the fluctuation of period-specific values from period to period.
