Final answer:
ODTAs are officially appointed in writing through documentation that details their role's responsibilities, reflecting the importance of formal record-keeping in government and military organizations.
Step-by-step explanation:
Organizational Defense Travel Administrators (ODTAs) are appointed in writing within a government or military setting to manage and oversee travel policies and regulations. Although there is not a specific form mentioned for this appointment, it is typically conducted through official documentation that outlines the duties and responsibilities of the role.
This is in line with organizational practices where reporting relationships are vital for internal communications and accountability, as evidenced by the management structures in organizations like NASA, where reporting to Congress is a requirement for oversight and funding.
The principle of ODTAs being appointed in writing is reflective of the standards of transparency and formal record-keeping within government and military organizations.
