Effect of Running the Process

Cobra first validates that the status date for the project exists in the rolling wave calendar file when you run the rolling wave process.

Cobra confirms that the dates represented by the number of periods before and after the status date in calendar set 01 of the rolling wave calendar exist in the project calendar. The process removes the weekly periods from the project calendar which occur before the rolling wave start date, and adds any dates required to the rolling wave finish date.

The spread from monthly to weekly is a linear spread which follows the spread settings for the project (for example, Linear Spread, Spread using hours, or Spread using working days). Since weekly earned value requires close integration with the schedule, the Spread using working days option is recommended. This option makes the weekly spread of Cobra data more closely match the schedule. The holidays in the Cobra calendar need to match the holidays found in the schedule calendar for consistent spreading between the two applications.
