Ability to Detect Changes to a Specific Field

I would love to have the ability to send a notification or email if a specific field is changed in an object. For example, if a Due Date is changed in my Work Order object, all managers must be notified. I know there are work arounds for this, but I would love to have this kind of granular accessibility. I use Zapier and I wish they allowed for this. Unfortunately, they only allow you to detect if an entire record is updated rather than a specific field. It's so important for me to know when specific fields are updated rather than a record as a whole.
