4. On-site Quality Assurance Should be independent of the production Tasks specific to the first assembly: Take ownership of the draft procedures Follow the work in progress Modify/update the procedure in work according to lessons learned Photographic support Text update support Feedback to worksite Take action to modify procedures to come that may be affected by current changes General Tasks: Keep a manufacturing/assembly file up to date as work progresses Manage results of QA tests including preventive/corrective actions on non-conformities

5. Estimates of Time Required Recently, three people well informed about our project, did 3 independent estimates Of these, one person considered the assembly in “production-line” terms where – All resources are in place meaning: All parts immediately to hand Procedures fully tested and validated All tooling fully tested and validated Clean-room assembly staff well trained and practiced Unforeseen problems very largely ironed out of the process – This could also be called a well mastered “routine” activity. – Where we had already assembled a few cryo-modules of the same type – Where the total time required comes close to the sum of the times needed for the suite of component activities

7. Real Time required? Our situation for the first cryo-module is quite different; New activity at CERN, new people, new tooling, new draft procedures, new QA activities. Equipment and tooling is now arriving on a just in time basis

8. What may we expect in reality? A first prototype – Debugging on 1 st CM; will be better on 2 nd – Some Re-work on components, procedures New activity, new clean-room, new tooling: – Running in phase may be long – Incomplete learning curve on 2 units (just debugging) Missing resources: slow build-up of assy team: – Specific training is needed on CM assembly New Clean-room: – Training is needed for productive clean-room work Uninterrupted work depends on “continuous flawless coordination” around the assembly (inside and outside the clean-room) Reasonable? …
