Case Study Prompt

A bank has a loan-issuing operation that requires the following steps:

  • The loan application is generated at a branch office.
  • A complete applicant background check is performed at the branch office.
  • The application and background check are sent to a loan processing office.
  • The background check is updated and verified (this takes much less time
    than original check).
  • The loan is either approved or denied.

The bank is considering getting rid of the first background check and only relying on the loan processor’s check to speed the process up. If the loan processor does the whole check with the proposed new software system, the check takes one additional hour per application at the processor’s office.

Should the bank implement the revised system?
