G⁰ Management Organization

The G⁰ Management Plan describes the processes and procedures to be used by the Project Manager, the Spokesperson, and the Collaboration to construct, install, and execute the experiment. It includes management organization for both the construction/installation and experiment/physics branches of the project with brief job descriptions for responsible parties. The Management Plan also includes a work plan, a framework for control and oversight of subsystems, a budget with specific contingency guidelines, and a summary of the schedule and manpower resources. A final Management Plan was submitted to DOE and NSF on December 14, 1998.

The G⁰ project has been separated into two management structures. One branch is concerned with the construction and installation of the experimental equipment and outlines the responsibilities for tracking budget, schedule and performance. Those responsibilities will begin upon approval of the management plan and they will be phased out when the apparatus has been commissioned in Hall C. The second branch outlines the responsibilities for determining and meeting the physics goals of the experiment including software, design criteria for hardware systems, development runs, running the experiment and analyzing the data. It is envisioned that as the construction and installation phase of G⁰ ends, the Experiment & Physics Organizational Chart will expand to include additional responsibilities for hardware subsystem managers such as overseeing ongoing performance and maintenance work.

The Construction & Installation branch of the G⁰ management organization specifies responsibilities for getting the experimental hardware installed and working in Hall C. The Project Manager (A. Lung, Jefferson Lab) together with her management team of integration physicist (S. Williamson, UIUC), project management support (G. Smith, Jefferson Lab), and engineering and technical support (W. Schneider, Jefferson Lab) have overall responsibility for execution of the hardware project including cost, schedule and performance control for both Jefferson Lab and outside collaboration groups. The organizational chart for the Construction & Installation branch of the collaboration is shown in Figure 7.

A complementary organization of the G⁰ collaboration, the Experiment & Physics Organization, has the responsibility of providing the necessary physics input to the design of the apparatus, as well as for commissioning the equipment after it is installed, and for the execution of the experimental program. During the construction and installation stage, one of the primary activities of this branch will be to provide advice based on physics considerations to those involved in construction, and to insure through careful monitoring of the design that the apparatus will be capable of carrying out the experimental program.

The organizational chart depicted in Figure 8 illustrates the division of responsibility and lines of communication in the Experiment/Physics Organization. Additional information about the role of the Spokesperson and the Executive Committee within the collaboration can be found in the G⁰ Collaboration Governance document [G098]. Table 2 lists the collaboration institutions, which have committed to provide manpower and equipment associated with various subsystems of G⁰. The organizational charts (Figure 7 and Figure 8) summarize individuals who lead the efforts to provide hardware and software systems. The G⁰ Collaboration consists of 83 physicists from 19 institutions. Each member is responsible for contributing to the design, construction, and commissioning of the G⁰ instrumentation, and for executing the experiment. Table 1 lists all current members of the G⁰ collaboration.

Table 2. The major responsibilities for provision of manpower and equipment for the G⁰ experiment is divided among the collaborating institutions as indicated above.

A summary table of the budget estimates for each major subsystem is shown in Table 3. Note that only the DOE and NSF funded portions of the experiment are included here. The significant contributions from the Canadian (NSERC funding) and French (ISN/IN2P3 funding) collaborators are described in scope in their respective MOUs, rather than in dollars. The total G⁰ cost estimate for DOE and NSF funding is $6780k. In order to demonstrate their commitment to G⁰, collaborators from institutions with ongoing DOE and NSF grants have pledged an additional $229k over the next three years. A summary of the funding sources, both previously committed and new requests, is shown in Table 4. Accounting for the previously committed funding from NSF grants to the University of Illinois and to Caltech, and from a DOE grant to Carnegie Mellon University, and the new commitment of $229k from ongoing grants, the outstanding requirement for new funding total is $3512k. An agreement has been reached between NSF, DOE and Jefferson Lab to provide the new funding identified in Table 3 and Table 4. The funding profile generated as part of this agreement is shown in Figure 9.

The schedule for the G⁰ project was developed using standard project management techniques and is based on planning sheets and milestones submitted by subsystem managers. The principal constraints on the overall schedule are the need to integrate the major subsystems in a reasonable order and the final funding profile as shown in Figure 9. A summary of the major milestones for subsystem completion, integration and installation is shown in Table 5. Currently, tasks on the critical path include the design and fabrication of the detector support, the assembly and testing of the detector modules, and the installation of components of the experiment in Hall C.
