O&S costs are often underestimated, especially in early phases

• Over time, constant-dollar estimates sometimes double or triple.
• Information is usually initially extrapolated from data for previous systems; later, experience with actual, fielded systems improves the data on which estimates are based.

Many newer systems are not meeting reliability and availability goals

• Fewer systems are meeting their reliability and availability goals when tested.
• This reflects a declining trend in the reliability and suitability of recently tested systems compared with those tested decades ago.
• All this affects the ultimate cost of O&S.

CAPE's O&S cost workload and resources are mismatched, making it difficult to do all it has been tasked to do

• Legislation has, at various times, established or added to what CAPE is supposed to accomplish. Staffing and related resources have not kept pace.
• Not all the information required to do these assessments is readily available to CAPE. This includes information held in various service systems. Data on contractor costs are also lacking. And CAPE needs more access to subject-matter expertise in many areas.
• As a result of such resource constraints, CAPE is not able to fully accomplish some of its duties.
