What does integrated logistics support in acquisition mainly aim to achieve?

Integrated logistics support (ILS) in acquisition primarily aims to ensure operational effectiveness throughout a system's life. This concept encompasses the planning and management of all logistical aspects associated with a system, ensuring that it remains reliable, sustainable, and capable of performing its intended functions from the initial acquisition phase through to decommissioning.

By focusing on the entire lifecycle of the system, ILS addresses the necessary support elements such as maintenance, supply chain management, training, and support equipment. This holistic approach helps to minimize downtime, optimize performance, and reduce costs, thus ensuring that the system remains operationally effective and ready for use when needed.

In contrast, other options represent objectives or activities that may not directly relate to the overarching goals of integrated logistics support. For example, a marketing plan is not a logistical function, while identifying technology upgrades and reducing staffing requirements are aspects that might be considered in facilitating operational effectiveness but do not encompass the full scope of ILS.
