Risks
Risk
Downspout Heatpipes not properly aligned
Test failures with new DAQ boxes
Interference between ACD and TKR or Grid
I&T performance
Hardware shortages
Mitigation
Use bond alignment tooling
Fit-check with X-LAT Plate
Work closely with ELX to resolve issues real time.
PDU engineer moved from ELX to I&T
Numerous measurement checks completed.
ACD and MECH personnel on-site during integration.
Add weekend shifts as required to maintain or improve
schedule performance.
Weekly review of hardware availability
Additional personnel added to I&T Material Logistics
Risks have been anticipated and plans put in place to mitigate them
