GSN Quality Assurance System Concepts of Operations

1. GSN Quality Assurance SystemConcepts of Operations • GSN-QC Coordination Meeting • IRIS DMC - 11/16/2011

2. GSN QAS Implementation PlanDetect, Document, Rectify, Share • Monitor Data, Metadata, and Operations • Standardized across GSN • Detect, document and rectify • using documented, objective, reproducible procedures • Review procedures and metrics • Inward facing (operations) and outward facing (users) components • User Feedback mechanism • Community monitoring (GSN and DMS SC’s) • Strategic guidance on operations

3. Roles and Responsibilities • GSN Management • Network Operators • Data Management Center • IRIS Governance (GSN, DMS SC’s)

4. GSN Management • Review Monthly and Quarterly QC reports • Review Maintenance plan with NetOps • Report to SC biannually • Coordinate with SC on Budgets and Strategies required for QA system • Report to IRIS Board (w/SC chair) on GSN Quality • Coordinate with IS and DS directors • GSN and DMS SC guidance on metrics and DMC-hosted QC tools

5. Network OperatorsASL and IDA Operations and DCC’s • Provide “inward” facing QC metrics • Operations driven • Archive QC time series (metrics) • Propose, review and update metrics • Incorporate metrics into maintenance action plan • metrics feed the station management process • Coordinate action plans with GSN Mgt and GSN SC • Standardize across NetOps and DCC’s • Share with DMC “outward” facing data, as appropriate

6. Data Management Center • Provide “outward” facing QC metrics • Provide framework for QC metric calculations • Share metrics with “inward” operations • Archive time history of metrics • Incorporate input from GSN mgt, NetOps, and SC’s on metrics • Provide user feedback mechanism

7. IRIS Governance • Review Quarterly and Biannual QC reports • Biannually: Generate written summary of recommendations to GSN mgt and Net Ops • Annually: Provide strategic guidance to GSN management and Network Operators on GSN data quality issues – particularly with chronic/expensive stations. • Do these stations contribute to meeting the goals of the GSN? • SC Chair: Report to the Board of Directors (SC chair and GSN program manager) on the state of the GSN Quality.

8. Multi-track process • Track 1: “Grab the low hanging fruit” • Begin work immediately and incorporate tools as they exist or come online • Track 2: • As new framework comes online, look to changes in implementation required • ie MUSTANG and associated post-processing that may be required • Process evolution • As new tools, metrics, goals evolve, so must the QAS
