Data quality before migration

Stated bluntly: the client item data is worse than they think, on essentially every manufacturing implementation. The common defects, including obsolete items that are often 20–40% of the master and structure components that do not exist in the item master. The assessment to run in week two, why you cleanse in the legacy system rather than the target, and the obsolescence conversation — usually the right answer and always uncomfortable. Bring the numbers, not the opinion.
