The Marine Corps is dependent on the use of electronic commerce (E-commerce) systems to acquire goods and services, both via commercial and federal sources of supply. Although E-commerce facilitates operational efficiency, the lack of established user access controls and codified management requirements throughout the logistics command hierarchy increases the risk of fraud, waste, abuse, mismanagement of resources, loss of property accountability, and a degradation in supply and materials operational readiness. Accordingly, this Order establishes policy and requirements for managing access to E-commerce systems in compliance with references (a) through (q) and implements logistics operational support requirements for E-commerce systems.
