Our HR area originally had 6 super users running add-ins to S3 Human Resources but a year later later we are now at over 60 super users. There have been some data integrity issues stemming from poorly designed, un-tested add-ins being applied directly to production. We have been asked to identify best practices for managing, testing, documenting, and communicating "Changes" that are being made via the add-ins. Does someone have a best practices model, document or policy or procedures they could share?
