Description
Growth in costs and schedules of aerospace projects is all too commonplace. Within NASA, about 70% of cost growth is attributed to underestimation of technical difficulty, 20% to major scope changes and 10% to external impacts. Schedule duration has increased by 50% over the last 15 years. Most growth problems can be traced to incomplete Phase A/B requirements definition, coupled with the resulting incomplete cost estimates.
NLS must be a cost effective, low cost transportation system to be viable. To achieve this goal a cost containment system is required which forces cost, technical and schedule to function together interlocked in a controlled management system.
