Understanding the effort and cost
Once the approach to each prioritized data quality issue has been identified, an approximate effort and cost estimate should be prepared, along with a timescale and plan for each issue.
- Sometimes it may be necessary to re-visit the prioritization at this point. If any of the issues will be exceptionally difficult to resolve, then it might be better to prioritize a different issue with a simpler resolution. This typically happens in the following situations:
- The approach selected is very manual and will consume more resources than are feasibly available
