5. http://www.GODAE.org GODAE August 2007 Contribution from F. Blanc for IGST, August 2007 What do we want to know ? What we know ! KPI stands for Key Performance Indicators.  The main goal of the KPIs is the provision of needed information to measure & evidence the end to end performance of GODAE.  KPIs are Quantifiable, Synthetic, Accurate, Targeted.  Among others, KPIs are also good tools to point out strengths and weaknesses. Following on KPI action

6. http://www.GODAE.org GODAE August 2007 Contribution from F. Blanc for IGST, August 2007 What do we want to know ? What we know ! 3 profiles of KPI users: –the GODAE Board  to report to the GODAE Patrons on feasibility & utility –the GODAE Operators  to report on implementation & usefulness, –the GODAE Users  to ensure that products are visible, accessible and useable, and have feedback on products use and needs Following on KPI action

7. http://www.GODAE.org GODAE August 2007 Contribution from F. Blanc for IGST, August 2007 What do we want to know ? What we know ! 3 key issues identified so far: –KP1: Quality of organisation (& efficiency)  “Do the systems do what they say they will do?” –KP2: Quality of production (& consistency)  “Have the productions reached the operational and qualified level?” –KP3: Use performance  “How well the products meet user needs?” Following on KPI action

8. http://www.GODAE.org GODAE August 2007 Contribution from F. Blanc for IGST, August 2007 What do we want to know ? What we know ! KP1: Quality of organisation (& efficiency)  Where are we in implementation?  Number of regional and global demonstrations  Clear visibility & understanding of systems  How many systems are operational or suited for reanalysis?  Can we evaluate the gain in implementation (faster or delayed)?  Long-term technical coordination solutions?  Other?  Commitment of systems to the data sharing plan?  Metadata  Vocabulary  Format  Access Tools  Reference fields Following on KPI action

10. http://www.GODAE.org GODAE August 2007 Contribution from F. Blanc for IGST, August 2007 What do we want to know ? What we know ! KP2: Quality of production (& consistency)  How far in operationality?  System status clear (research & development, reanalysis mode, demonstration, pre-operational, operational, stopped)  Dissemination/accessibility status clear (production OK, dissemination OK, timeliness, be it for real time or historical data, services failure)  Track of changes and key data streams clear (cf. synchronised observations)Long term issues (time series context & consistency)  Back-up scenario Following on KPI action

11. http://www.GODAE.org GODAE August 2007 Contribution from F. Blanc for IGST, August 2007 What do we want to know ? What we know ! KP2: Quality of production (& consistency)  How far in qualification? (report with a qualification status, may depend on system type - reanalysis, operational forecast, observations -)  agreement on metrics products  production set up  routine production  How is shown qualification?  Report with a qualification status (research & development, periodic/operational assessment)  Qualification data (random or regular validation report, ocean resolution achieved, forecast skill computation, model errors)  Dissemination & availability of the qualification indication Following on KPI action

12. http://www.GODAE.org GODAE August 2007 Contribution from F. Blanc for IGST, August 2007 What do we want to know ? What we know ! KP2: Quality of production (& consistency)  Is the products well defined & described (coherent and meaningful)?  Use of common vocabulary  Coherency in system description  Guidance for access  Guidance for use  Guidance for qualification Following on KPI action
