Organization Who is the Systems group? The systems group is managed by the Systems Engineer, Dennis Coyne. The Systems Scientist is Peter Fritschel. There are two principal groups that support the systems work, the Modeling group and the Interface Control Working Group (ICWG). The lead and members of the modeling group are TBD. The ICWG is comprised of representatives from each of the subsystems. In addition, the systems group will call upon the subsystem resources/expertise to help answer system level questions. (click on the organization chart for an expanded view) Responsibilities The responsibilities of the systems group are the following: system requirements development system design development oversight of subsystem requirements & design development technical configuration management technical interface management system level simulation system test & evaluation reliability assessment system level EMI/EMC evaluation Work Breakdown Structure (WBS) The systems WBS (LIGO.4.14.5…) is a sub-element of the Project Management (PM) WBS and is defined in the WBS dictionary. Deliverables The deliverables from the systems group are defined within the WBS dictionary. Schedule The schedule for the Systems tasks and deliverables are tracked in the overall advL project, Primavera schedule available on the advL Project Management web pages. Decision Tree/Process As questions or issued arise within the project, the first question to resolve is whether the scope is within a particular subsystem or whether it extends to the system level. If it is a systems issue to resolve, then the Systems Engineer determines the proper disposition of the issue for resolution as indicated in the diagram below. The ultimate decision authority depends upon the nature of the issue as indicated in the decision tree diagram.
