Update contact properties

Update the 'Industry' and 'Annual Revenue' properties for 42 contacts in the Mid-Market list. Set Industry to Software and Annual Revenue to $10,000,000 for all. Make sure these changes trigger no owner reassignment and add a note on each record: Updated industry and revenue for Q3 segment analysis. Confirm completion and list any contacts that failed to update.

Before I batch-update 42 Mid-Market contacts, make it easy for the reviewer: show a preview of the first five records with current Industry and Revenue, flag any records where Industry is blank or Revenue already differs, and highlight conflicts where a contact is in other segments so we can avoid accidental misclassification.

I pushed an update to set Annual Revenue for our Mid-Market list but a handful still show the previous numbers. Those records are owned by a different rep, and I didn't get an error. I'm worried the update was blocked by permissions or custom workflows I didn't know about. What is the most likely cause and the right troubleshooting step to ensure these properties change without breaking workflows?

Property updates keep triggering automation and owner changes because past rules are too broad. It costs us hours undoing mistakes. Which three changes to our property and workflow practices would stop accidental automations, and what single guardrail would ensure future batch updates are safe for shared records?
