What is ILS?

Integrated Logistic Support (ILS) is a structured, co-ordinated and iterative approach to the procurement of supportability of systems whether they are bespoke or off-the-shelf. The increasing cost of system ownership has led major customers to apply the principles of ILS to all new projects as a mater of policy.

The objectives of ILS are to:

  • Ensure that supportability considerations influence the design of a system or, where this is already fixed, to define the impact of the design on supportability
  • Identify and develop support requirements which are related to system design and readiness objectives
  • Acquire the necessary support
  • Provide the required support in-service at the optimum Life-cycle Cost

ILS ensures that all the elements contributing to the support of a system are defined, analysed and costed for their impact on supportability. The elements included in ILS are:

  • Availability, Reliability and Maintainability (ARM)
  • Safety
  • Life-cycle Costing (LCC)
  • Logistic Support Analysis (LSA)
  • Spare part requirements
  • Maintenance policy
  • Spares Support
  • Technical Publications
  • Support systems and Equipment
  • Personnel
  • Support outsourcing
  • Off-the-shelf hardware and software end-of-production/support strategies
  • Support Facilities
  • Training
  • Installation & Field Support
  • Packaging, Handling, Storage & Transportation (relating to the support process)

ILS should normally be conducted as a collaborative effort by the system customer and the system supplier. Design for support can be optimised only if there is a thorough understanding of the structure, skills and costs of the support processes.
