  • Reliability

    We seek feedback and advice about the methods we use to estimate the gap from our external and internal subject matter experts. Based on the advice and assessment, the reliability rating for this estimate is medium (with a score of 16).

    We are looking to improve the reliability in the future by drawing on further data sources so that we can remove or improve upon assumptions that we currently use.
