The impact of ILS is often measured in terms of metrics such as reliability, availability, maintainability and testability (RAMT), and sometimes System Safety (RAMS).
Tradeoffs may be required between elements in order to acquire a system that is: affordable (lowest life cycle cost), operable, supportable, sustainable, transportable, and environmentally sound.
These actions will enable the system to achieve the operational readiness levels required by the warfighter at the time of fielding and throughout the life cycle.
ILS Sabbaticals are normally taken in developing nations - allowing the practitioner an insight into sustainment practices in an environment of limited materiel resources.
It is conducted to evolve and establish requirements and tasks to be accomplished for achieving, restoring, and maintaining the operational capability for the life of the system.
Manpower requirements are developed and personnel assignments are made to meet support demands throughout the life cycle of the system.
This element defines qualitative and quantitative requirements for the training of operating and support personnel throughout the life cycle of the system.
This element includes resources and procedures to ensure that all equipment and support items are preserved, packaged, packed, marked, handled, transported, and stored properly for short- and long-term requirements.
This element includes planning and programming the details associated with movement of the system in its shipping configuration to the ultimate destination via transportation modes and networks available and authorized for use.
PHS&T planning must consider: The Facilities logistics element is composed of a variety of planning activities, all of which are directed toward ensuring that all required permanent or semi-permanent operating and support facilities (for instance, training, field and depot maintenance, storage, operational, and testing) are available concurrently with system fielding.
The basic requirements that need to be considered as part of design interface include: The references below cover many relevant standards and handbooks related to Integrated logistics support.
