Implementing the GSN Quality Assurance System: Strategies and Operations

This document outlines the GSN Quality Assurance (QA) System's operational concepts, detailing the strategies for detecting, documenting, and rectifying data quality issues. It emphasizes standardized processes across the GSN network, including inward and outward-facing components to ensure effective user feedback and community monitoring. The GSN Quality Control (QC) meetings and quarterly reports provide a framework for assessing metrics, coordinating with Network Operators and the Data Management Center, and offering strategic guidance to improve data quality continuously.

  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
