Delays in incremental review process may impact cost & schedule Detailed software development plan, schedule and review points established (3/24/03). Early integration of software to target hardware via EM plan (Sept 03) Extensive use of test bed (Feb 04 and beyond) On track Elec/2 21 Moderate Tower Power Supplies Cost & Schedule depend on bids received in response to RFP Proposals may exceed allocated schedule & funding Bids expected 3/25/03 Assess schedule problem Determine cost impact to maintain schedule Negotiate with vendor to minimize impact Develop minimum impact re- plan & pursue CCB approval On track
