Forecasts
A forecast is an estimate of the final cost of the project, created at any given time during the course of the project.
You can have an unlimited number of forecasts in Cobra. Each forecast is defined with a different class and can use a different set of rates and/or method for calculating or maintaining the forecast.
A forecast in Cobra is defined by the Estimate To Complete (ETC). To report an Estimate At Complete (EAC), you add the actual class and forecast class together:
Estimate at Complete (EAC)=Actual Cost + Forecast (ETC)
Cobra performs this calculation during reporting by selecting the cost set EAC.
To report on multiple forecasts, you create new cost sets and include the forecast and actual cost classes needed for your report. This is useful for maintaining a customer forecast, an internal forecast, a statistical forecast, and so on.
Use the Retain EAC method to edit the Estimate At Complete (EAC) value and report the new EAC value. This is useful if you want to report the same value month after month.
Freezing the forecast lets you copy the actual costs and forecast to a new class to support gated actuals.
Cobra lets you generate forecasts using either manual or statistical entries.

- Manual Forecasts
If you are using a manual forecast, you can use the Reclass utility to copy the budget to the forecast. The Reclass process automatically identifies the level of the forecast class, as well as the date set used by the forecast, to update the new forecast and dates. - Statistical Forecasts
Statistical forecasts use past performance to calculate a performance factor (PF) that is applied to the remaining budget. - Retain EAC
Use the Retain EAC method to edit the Estimate At Complete (EAC) value and report the new EAC value. This is useful if you want to report the same value month after month. - Forecast Calculations
Most forecast methods depend on accurate values of cumulative actual costs and earned value and on the latest estimated dates for the remaining work in the project. - How Cobra Spreads ETC
When calculating forecast costs, Cobra spreads the ETC for each work package or control account between the estimated start and finish dates (or between the status date and the estimated finish date for in-progress work). - How Cobra Calculates Forecast Scale EAC
Cobra runs the Calculate Forecast process using scaling methods such Hours, Currency, and Hours and Currency. - Frozen Forecasts
A frozen forecast is created by copying the actual costs and the forecast classes defined in a cost set (selected when you freeze the forecast) to a new class. - Procedures
Use the procedures to create and set up forecasts and update forecasts by exporting or importing data to Excel. - Calculate Forecast Wizard
To calculate forecasts, you must complete the information required on each page of the Calculate Forecast wizard.
