Elements Of A Qa/Qc System - Part 2
Good practice for QA procedures requires an objective review to assess the quality of the inventory, and also to identify areas where improvements could be made. The inventory may be reviewed as a whole or in parts.
- QA procedures are utilised in addition to the Tier 1 and Tier 2 QC. The objective in QA implementation is to involve reviewers that can conduct an unbiased review of the inventory. It is good practice to use QA reviewers that have not been involved in preparing the inventory.
- Preferably these reviewers would be independent experts from other agencies or a national or international expert or group not closely connected with national inventory compilation.
- Where third party reviewers outside the inventory agency are not available, staff from another part of the inventory agency not involved in the portion of the inventory being reviewed can also fulfil QA roles.
Documentation, Archiving and Reporting
Internal documentation and archiving :- As part of general QC procedures, it is good practice to document and archive all information required to produce the national emissions inventory estimates.
Reporting:- It is good practice to report a summary of implemented QA/QC activities and key findings as a supplement to each country national inventory. However, it is not practical or necessary to report all the internal documentation that is retained by the inventory agency.
- The summary should describe which activities were performed internally and what external reviews were conducted for each source category and on the entire inventory in accordance with the QA/QC plan.
- The key findings should describe major issues regarding quality of input data, methods, processing, or archiving and show how they were addressed or plan to be addressed in the future.
