Customize contact properties

We need the contact property for Annual Contract Value updated across sales and marketing. Create a custom property named Annual Contract Value (ACV) with currency type, set default to zero, make it visible on the contact record and in list views, and add it to the new deal creation form. Apply the property to all contacts created after January 1, 2024, and notify the sales ops team and Jenna in Rev Ops when complete by Wednesday at noon.

Before I roll this out, make the property easy to use: place Annual Contract Value near job title and company size on the contact record, add a tooltip explaining acceptable values and rounding rules, provide a short validation rule to prevent non-numeric entries, and prepare a quick two-sentence note for sales explaining when to update ACV versus when ops will populate it.

I added Annual Contract Value as a currency contact property but the reps say it isn’t showing up for accounts they manage. I don't know if it's a visibility setting, a field placement on the contact layout, or a permission issue. Should I check property visibility by team, confirm it’s on the correct contact record type, or ask one rep for a screenshot to diagnose? What’s the most likely cause and the quickest fix?

Over the past year we’ve created dozens of custom contact properties but adoption is low and records diverge. Where am I wasting time—designing too many fields, not enforcing who owns them, or failing to train reps? Recommend one rule and one small enforcement mechanism I can apply now so future properties get used and old ones get retired on a schedule.
