ICRP Recommendations (1)

• Baseline Funding– NASA did not establish an adequate cost and

schedule baseline at JWST’s Confirmation Review milestone, and recommended four specific steps be taken to establish a realistic baseline.

4AAS 217th Meeting

ICRP Recommendations (2)

• Independent Analysis Capability– NASA Headquarters should have a robust

independent cost and program analysis capability, and recommended a stronger role for the Office of Independent Program and Cost Evaluation (IPCE).

5AAS 217th Meeting

ICRP Recommendations (3)

• Program and Project Management– Recommended that JWST be elevated to a new

organizational entity at Headquarters– Implementation phase of JWST project requires a

different management approach than the Formulation phase

ICRP Recommendations (4)

• Additional Items– NASA program/project governance policy– Program, Project, Industry communication– Potential Risk in Integration and Test

• ICRP Endorsed findings of the TAT– System Engineering

• Establish a plan that provides the required level of experience and involves appropriate prime contractor personnel before changing system engineering accountability

– Project Scientist and Science Team• Recommend this role be strengthened
