The Large Synoptic Survey Telescope (LSST) project has evolved from just a few staff members in 2003 to about 100 in
2010; the affiliation of four founding institutions has grown to 32 universities, government laboratories, and industry.
The public private collaboration aims to complete the estimated $450 M observatory in the 2017 timeframe. During the
design phase of the project from 2003 to the present the management structure has been remarkably stable. At the same
time, the funding levels, staffing levels and scientific community participation have grown dramatically. The LSSTC
has introduced project controls and tools required to manage the LSST's complex funding model, technical structure and
distributed work force. Project controls have been configured to comply with the requirements of federal funding
agencies. Some of these tools for risk management, configuration control and resource-loaded schedule have been
effective and others have not. Technical tasks associated with building the LSST are distributed into three subsystems:
Telescope & Site, Camera, and Data Management. Each sub-system has its own experienced Project Manager and
System Scientist. Delegation of authority is enabling and effective; it encourages a strong sense of ownership within the
project. At the project level, subsystem management follows the principle that there is one Board of Directors, Director,
and Project Manager who have overall authority.
