The figure below shows a high level schedule for the major work elements. The immediate effort involves the simulation, reconstruction and related tools (eg event display), and code infrastructure (eg release management); medium term is the DPF, Calibrations and deciding on event database technology; the long term is occupied by building the science analysis tools and polishing up the short and medium term items.
Shown below is the manpower estimate vs time [figure needs remaking for axes etc; horiz axis is time, measured in Quarters. We are in Q5 now. Might need some detailed adjustment to match timeline]. At present, most of the effort is going into simulation/reconstruction, analysis tools and user support. As we move into the DPF, Calibration and Science Tools areas, we will need to expand the effort. This will be further discussed in the Open Issues section.
Here are the assumptions made for the manpower estimate. SAS occupies a unique position in the collaboration in that not only does it have deliverables, but it is also a service organization. This implies an element of ongoing support for users, as well as for upgrades, maintenance and support of the software products.
1 FTE GEANT4 during the development phase and 1/2 FTE ongoing (Italy)
1/2 FTE sources (Japan)
2 FTE CAL - simulation and reconstruction (NRL, France)
2 FTE TKR - simulation and reconstruction (SLAC + Italy)
½ FTE for ACD - simulation and reconstruction (GSFC)
1 FTE combined for Trigger, Background Rejection studies (there may be odd scientists contributing as well)
1 FTE for tools development (GSFC)
1 FTE package & user support (SLAC)
1 FTE code release & verification (SLAC)
1 FTE event display (Italy)
1 FTE extra for duration of each test
Guessing 3 FTEs to support 7 scientist programmers (estimated 40 MY work). Starting in FY ’02.
Data Processing Facility
1 FTE automated server (~1 year) – main activity in FY02, followed by a burst a year before launch
1 FTE instrument diagnostics – build up 1.5 yr before launch
1/2 FTE support of DPF pre-launch
Calibration (starts ~3/2002?)
1 FTE for machinery for calibrations
2.5 FTE for subsystem algorithm development (perhaps more – from NRL, France & Italy).
1 FTE code architect
1 FTE manager
In more detail, this results in the effort vs time chart shown below.
