STUDY SUMMARY - IPMU

SUMMARY REPORT
WIDE FIELD FIBER-FED OPTICAL
MULTI-OBJECT SPECTROMETER (WFMOS)
• Positioner EM completion.
• Detector delivery to JPL for coating and delta doping.
• Software delivery to spectrograph and positioner/PFI I&T.
• Spectrograph/detector system ship to Subaru.
• All final subsystem hardware deliveries to I&T.
• Software and Data Pipeline delivery to Subaru.
• Positioner/PFI ship to Subaru.
• Completion of ATP.
Successful completion of major reviews according to the standards associated with SRR,
PDR, CDR, and PSR are good indicators of overall progress as well as the completion of significant
tests and delivery of hardware assemblies. The detailed set of milestones along with clear
definition of success will be developed further at the start of the study.
Schedule tracking and management are important to this project as they are directly related to
cost. Any schedule slip in one area can result in not only additional effort in that area, but holding
personnel longer in other subsystems if it also impacts the final delivery date. A similar approach
to the cost tracking is taken, collecting schedule status from all the partners on a monthly
basis and using a single integrated project schedule to assess the trends.
Options for schedule recovery are also actions that typically do not impact performance, but
may increase development risk. These can be items such as increasing workforce to accelerate
tasks, replacing analysis with test, eliminating lower-level tests and capturing those objectives at
higher level tests, staggered deliveries, and descopes. Depending on project costs, expedite fees
to vendors may be used.
