James Webb Space Telescope: Actions Needed to Improve Cost Estimate and Oversight of Test and Integration

The National Aeronautics and Space Administration (NASA) has provided significantly more time and money to the James Webb Space Telescope (JWST) than previously planned and expressed high confidence in the project’s new baselines. Its current cost estimate reflects some features of best practices for developing reliable and credible estimates. For example, the estimate substantially meets one of four cost characteristics–comprehensive–that … Read More
