GODAE August 2007 Contribution from F. Blanc for IGST, August 2007 Data server report  Do we want to revise report format ?  Report made available on the public web (‘cms’ format prefered)  KPI ? (action 28) Report on Product & Data servers Outcome 2

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

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

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

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

GODAE August 2007 Contribution from F. Blanc for IGST, August 2007 KP1: Quality of organisation (& efficiency)  Has this ease product access?  Availability of products  Confidence in products  Any integrated application ….  Other ?  For what they are used?  Countries & visitors (evolution curve)  Range of applications, and number per year  Range of services (ocean catalogues, operational applications) Following on KPI action What do we want to know ? What we know !

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

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

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

GODAE August 2007 Contribution from F. Blanc for IGST, August 2007 What do we want to know ? What we know ! KP3: Use performance  How the user is aware of products? (visibility of key data streams)  In Google  Federated catalogues  List of available systems (with user guidance)  List of products servers (with user guidance)  List of integrated services (with user guidance)  How simple to access the products? (effective distributed dissemination system)  Registration process  Interoperable use (pull) versus push system  Advanced tools (extractors)  Internet capacity  Distribution services capacity (volume/needs) Following on KPI action

GODAE August 2007 Contribution from F. Blanc for IGST, August 2007 What do we want to know ? What we know ! KP3: Use performance  How they are used?  Datasets used  Parameters selected  Space and time window  How often  Preferred services (catalogue, access, advanced tools)  Any user feedback?  Is the product well understood? Strengths and drawbacks, Complaints  Showcases and age of showcase  Number of distributed working group and size of the group  Number of projects or collaborations liaised to GODAE  Benefit? Other ? Following on KPI action

Report on Product & Data servers Outcome 2 Does GODAE need a quantitative measurement system ? What indicator is worth to be maintained and monitored in time? Is the context, clear enough to get coherent & useful indicators ?
