Assessment methods vary widely in cost and effectiveness. The ideal comparison of the data to the real world entities tends to be expensive, while the least expensive options (comparison to proxy sources of data, sampling) may yield misleading results. To picking the right assessment method(s), it helps to know how the results of the assessment will be used. Creating a template for the final accuracy assessment report may help guide the many choices and keep procedures focused on the final, useful result. Document any root causes found. Do not update database during the assessment process.
