Multi-Factor Console for Updating Critical Business Parameters Executed by Software

Major business policies, especially in financial services, are often driven by some simple parameters that are executed in software. E.g., for a lender, what interest rate is being charged.

There is typically a dashboard accessible to a small number of users with authorized elevations, to enter these values. In general, that works fine, but there may be concerns about data-entry mistakes or deliberate sabotage (less probable). I think a good solution involves:

• Purpose-built UI (console), limited of course to an appropriate, small user group.
• Require multi-factor -entry to implement a change: i.e., 2 or more members have to independently submit the update (exact number is configurable, depending on the sensitivity--but in general, I think 2 is the magic number).
• Add some UX niceties for workflow—e.g., showing pending updates where only 1 entry has been made, reminders if 2nd entry is overdue.
• Email the entire group whenever a change is initiated and completed.
