Yet Another Webb Problem Review Panel

NASA Announces Independent Review Board Members for James Webb Space Telescope

"The Independent Review Board review process will take approximately eight weeks. Once the review concludes, the board members will deliver a presentation and final report to NASA outlining their findings and recommendations, which are expected to complement recent data input from Webb's Standing Review Board. NASA will review those findings and then provide its assessment in a report to Congress at the end of June. Northrop Grumman Aerospace Systems, the project's observatory contractor, will proceed with the remaining integration and testing phase prior to launch."

Management Shake Up on Webb Space Telescope, earlier post

"NASA's Science Mission Directorate (SMD) is taking essential steps to refocus efforts to ensure a successful mission for the agency's James Webb Space Telescope (JWST) after an independent assessment of remaining tasks revealed more time is needed for testing and integration to meet a new launch window of approximately May 2020."

Management Changes at Webb Announced (2010)

"For the past 8 years, the JWST team has been led by Phil Sabelhaus, and in my view, no one could have been more effective leading this government, industry, and international team, especially in light of the enormous challenges and constraints."

"The problems causing cost growth and schedule delays on the JWST Project are associated with budgeting and program management, not technical performance. The technical performance on the Project has been commendable and often excellent. However, the budget baseline accepted at the Confirmation Review did not reflect the most probable cost with adequate reserves in each year of project execution. This resulted in a project that was simply not executable within the budgeted resources."
