Final answer:
A Director of Operations must sign specific Financial Management System forms to change their signature, the form number varies by organization.
Step-by-step explanation:
A Director of Operations (DO) needs to sign certain Financial Management System (FMS) form(s) to officially amend or update their signature within an organization's system. The specific form number can vary based on the organization's own internal forms catalogue or the specific software system it uses.
It's important for any changes to a signature to be properly documented to ensure the integrity of the financial transactions and maintain an audit trail. If you work as a DO or in a similar role, you would typically receive guidance on the correct forms from your finance department or through internal policies and procedures.
