  functionality has been successfully performed.
• Move to exploitation phase where we harness that
  functionality to meet LHC requirements
• The requisite software needs to be deployed and
  tested over the coming months
• Staged approached
• Individual systems
• HWC shadowing
• Dry runs
• Injection
• Sector
• Nsector
