SUMMARY OF EFFORT REQUIRED TO COMPLETE
ANCILLARY SERVICES REDESIGN SOFTWARE FUNCTIONALITY

Below is a summary showing numerical representations of the relative amounts of effort required to complete each of the Ancillary Services redesign software enhancements already approved or under consideration by the Board for implementation this summer. 

The Skills and Effort that is required to implement the items already approved by the ISO Board and the new Ancillary Service Design Elements are divided into three groups based on the people who will do the work:

1.	Balance Energy and Ex-Post Price Calculation (BEEP)
2.	The Scheduling Infrastructure and Scheduling Applications (SI/SA) System, for scheduling and bidding.
3.	The Balance of Business System (BBS), for settlement and billing.

The items within each column utilize roughly the same resources and are roughly substitutable for each other.  Incorporated in the numerical values is an assumption that the ISO will delegate, to the extent possible, work to consultants/vendors, so that the work depicted is only the remaining staff work.
