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

An approach involving a third party (that is, paying for correct data) is more expensive than initially anticipated

Momentum is important in data quality initiatives. If an issue is problematic, even where the priority is high, it can be better to move on to an issue that can be progressed efficiently.
