This resource provides detail about each data quality metric. For each metric the following information is provided: metric reference, report, category/sub-category, expanded description, data/tables interrogated, specific exceptions, dimension, asset management importance, grade ranges, purpose, consequence of poor-quality data, potential reason(s) for not being at the expected standard unique to this metric, data quality metric RAMM SQL, record by record exceptions RAMM SQL.
REG developed a survey for the sector to gain a greater understanding of the root causes for inconsistent data quality to support the development of a sector-wide improvement programme.
Changes to the ONRC data quality framework, metrics and reports are outlined in the change register.
