Overview

IEC 60300-3-12:2011, titled "Dependability Management – Part 3-12: Application Guide – Integrated Logistic Support (ILS)", is an international standard published by the International Electrotechnical Commission (IEC). This standard provides comprehensive guidance on establishing an effective Integrated Logistic Support management system. Its purpose is to help suppliers of all sizes optimize products for the entire life cycle, ensuring quality, reliability, and supportability that meet purchaser requirements.

This application guide aligns with current dependability standards and offers a holistic view of the ILS process, including best practices and logistic data analyses. It supports organizations in integrating logistic considerations early in the design and product management phases to improve long-term operational dependability and reduce life cycle costs.

Key Topics

The standard covers a broad spectrum of topics crucial to implementing ILS effectively:

• ILS Principles and Objectives
  Explanation of core objectives such as enhancing product supportability, reliability, maintainability, and availability throughout the life cycle.

• ILS Structure and Elements
  Detailed descriptions of the key elements involved in ILS, including maintenance planning, provisioning spares, technical documentation, personnel training, and facilities management.

• Planning and Management
  Guidance on establishing management structures, responsibilities, and documentation controls to ensure consistent and reviewable ILS activities.

• Logistic Support Analysis (LSA)
  Methods to analyze logistic support requirements and identify maintenance tasks, support equipment, and spare parts to optimize supportability.

INTRODUCTION
The successful operation of an item in service depends to a large extent upon the effective
acquisition and management of logistic support in order to achieve and sustain the required
levels of performance and customer satisfaction over the entire life cycle.
Logistic support encompasses the activities and resources required to permit operation and
maintain an item (hardware and software) in service. Logistic support covers maintenance,
manpower and personnel, training, spares, technical documentation, packaging, handling,
storage and transportation, logistic support resources and disposal. In most cases,
maintenance support is considered to be synonymous with logistic support. Logistic support
may also include operational tasks but the differentiation between operational and
maintenance tasks varies with industry and individual practices.
The cost of logistic support is a major contributor to the life cycle costing (LCC) of an item and
increasingly, customers are making purchase decisions based on life cycle cost rather than
initial purchase price alone. Logistic support considerations may therefore have a major
impact on item sales by ensuring that the item can be operated and supported at an
affordable cost and that all the necessary resources have been provided to fully support the
item so that it meets the customer requirements.
Quantification of logistic support costs allows the manufacturer to define the logistic support
cost elements and evaluate the warranty implications. This provides the opportunity to reduce
risk and allows logistic support costs to be set at competitive rates.
Integrated logistic support (ILS) is a management method by which all the logistic support
services required by a customer can be brought together in a structured way and in harmony
with an item. ILS should be applied to ensure that supportability considerations influence the
concept and design of an item and to ensure that logistic support arrangements are consistent
with the design and each other throughout the item’s life.
The successful application of ILS will result in a number of customer and supplier benefits.
For the customer, these can include increased satisfaction, lower logistic support costs,
greater availability and lower life cycle costs. For the supplier, benefits can include lower
logistic support costs, a better and more saleable item with fewer item modifications due to
supportability deficiencies.
This part of IEC 60300 provides guidance on the minimum activities necessary to implement
an effective ILS management system for a wide range of commercial suppliers.

4 Principles of integrated logistic support (ILS)
4.1 ILS objectives
The integrated logistic support (ILS) should ensure that
– logistic support considerations are integrated into item design at a very early stage in the
design process – preferably at the concept stage,
– logistic support arrangements are developed that are consistently related to design
(including intended use and intended environment of the item) and to each other,
– the necessary logistic support is provided at the beginning and during customer use and
disposal at optimum cost,
– improvements are allowed to be made in the logistic support of an item throughout its life
– and to support necessary modifications; for example, changes required to deal with
obsolescence.
ILS should improve the item (by influencing the design to provide the most economic and
efficient logistic support solution), improve the logistic support system and minimize the life
cycle cost while ensuring that the needs of the customer and business are met.
4.2 Application of ILS
ILS should be applied to the design and development of an item to ensure that all the logistic
implications of introducing the item have been properly considered so that it can be supported
in the most cost effective manner.
ILS is applicable to all items, including very large items (such as a power plant or a paper mill)
and provides a methodology for the identification and optimization of the logistic support
requirements for the individual items that constitute the plant.
The degree of application of ILS and the associated LSA will vary accordingly with regard to
the degree of design freedom, technical complexity, cost of the item and other factors.
A logistic support analysis (LSA), which comprises the selective application of a series of
analysis activities, should be used to assist the design in complying with supportability and
other ILS objectives.
If an item is a completely new development it may be necessary to apply most of the LSA
activities, but where an item is identified as an existing item, it may not be necessary to apply
all the activities. This is referred to as tailoring and addresses the depth of analysis to a cost-
effective level based on maturity and the type of item.

–   – 60300-3-12  IEC:2011
ILS results usually have to be modified and updated over the life cycle since changes are
likely to occur due to
– experience gained from failures,
– changes in logistic support resources such as suppliers of spare parts,
– improvements in maintenance technology and procedures,

– modifications incorporated in the items,
– human aspects associated with operation and maintenance activities (IEC 62508),
– changes in operating conditions or environment.
4.3 Elements of ILS
The following elements of logistic support are covered by ILS, and may include, but are not
limited to:
– maintenance planning;
– spares/materials;
– support equipment (including tools and test equipment);
– technical documentation;
– manpower and personnel;
– training;
– packaging, handling, storage and transportation;

– reliability centred maintenance (IEC 60300-3-11);
– specification of maintenance support services (IEC 60300-3-16);
– dependability requirements (IEC 60300-3-4).
In addition, ILS interfaces with
– project management,
– risk management,
– safety and hazard analysis,
– human factors analysis,
– trials and acceptance,
– configuration management,
– quality,
– environmental requirements,
– design reviews (IEC 61160) ,

and will reflect and contribute to the approach in these areas.
The activities and procedures for these interface areas are covered in other IEC standards.
4.4 Structure of ILS
ILS is structured so that it can assimilate key areas and logistic support elements to optimize
the logistic support required for a system. A simplified diagram illustrating this structure is
shown in Figure 1.

The initial stages involve the breakdown of the system into LRIs and the identification of LRIs
which require detailed analysis (sometimes referred to as LSA candidates or maintenance
candidates). In some cases, the selected LRI is composed of numerous items and it may be
necessary to conduct further analyses to optimize maintenance.
Figure 2 illustrates at a high level how the LSA activities interrelate with each other and with
the design activities.

The general logistic support strategy and customer requirements logistic support concept is a
basic description of the maintenance support expected to apply to the item. It is usually
defined within the customer profile and should be provided to both the design and logistic
support team to ensure that the item will be supported in its intended environment. As the
design progresses, the initial logistic support concept will be confirmed and expanded.
The design configuration and design performance data provides basic design and performance
information. The design information is progressively analysed in terms of its logistic support
implications under the LSA in Clause 6. Reliability and maintainability characteristics and
FMEA/FMECA are fundamental inputs to these analyses. The R&M characteristics indicate
the likelihood of item failure and time to restore and hence the maintenance and logistic
support effort and resources required. The FMEA/FMECA indicates the likely causes of failure
of the item and provides feedback to improve the design. For the final design and logistic
support concept, the FMEA/FMECA provides the input for the systematic identification of all
the maintenance and logistic support resources required for the item through the use of
maintenance activities and logistic support activities described in Clause 8.
Evidence gathered during operation (customer involvement), provides feedback to improve
the item. Proving trials are normally conducted on new items to demonstrate stated
performance or fitness for purpose; such trials should include the logistic support
arrangements. The testing of the design and proving of the logistic support arrangements are
covered under verification of logistic supportability (see Clause 10).
Analyses associated with life cycle costs, ensure that cost considerations (throughout the life
of the item) are included when establishing the preferred solution.

Integral with the LSA activities is the LSA database which provides the mechanism and
repository for the LSA and documents the detailed logistic support to be provided as a result
of the logistic support activities enumerated in Clause 6. To maximize the benefit, the outputs
and results of the LSA should be recorded in a controlled and structured LSA database. The
creation of an electronic LSA database is recommended as the most viable means to store
and control the information obtained. Further details covering interfaces, tailoring and
configuration management are discussed in Clause 12.
5 Planning and management of ILS
5.1 General
The planning and management of ILS addresses the programme of work required to carry out
the ILS activities. For a complex item, this is a major factor in the success of the ILS
programme. The planning of ILS should ensure that all ILS and LSA activities, responsibilities
and internal and external interfaces at each phase of the design and ongoing life of the item
are clearly defined. The type of maintenance task (for example, preventive – condition based,
preventive – pre-determined, corrective – immediate, and corrective – deferred) may require
different ILS approaches to be adopted. Examples of the ILS management and planning
activities are listed below:
– determine and agree on ILS responsibilities, including logistic information, and interfaces
with the owners, users, operators, manufacturers, item design teams, suppliers and/or
customers;
– define programme of LSA activities to be undertaken (see Clauses 6, 8 and 11);
– determine method for providing design guidance;
– define maintenance support resources;
– plan and put in place review processes, both informal and formal, to audit the design and
the ILS programme;
– apply operational improvement processes for the maintenance and maintenance support
resources during the operation and maintenance phase;
– produce and maintain ILS planning documentation to control the ILS programme;
– provide input to decisions on trade-offs between functional needs, capability, life cycle
cost and dependability;
– monitor and control the ILS programme of work;
– identify risks associated with the ILS programme and propose actions to address these
risks.
It should be noted that ILS management and planning activities require an understanding of
the legislative requirements. Examples are WEEE, RoHS and REACH . Where a global
service is intended, these requirements may differ across countries.
5.2 Management structure and responsibilities
A single person is normally appointed, usually referred to as the ILS manager, with
responsibility for the overall programme of ILS activities. The responsibilities of the ILS
manager are the ILS management and planning activities defined in 5.1 and other detailed
activities as allocated. The principal activities of the ILS manager are to
– meet the requirements of the ILS/LSA plans,
– develop the logistic support-related technical characteristics of the item,
– coordinate and integrate inputs from the specialist disciplines,

Registration, evaluation, authorisation and restriction of chemical substances.

–   – 60300-3-12  IEC:2011
– coordinate maintenance support provided by contractors and subcontractors,
– coordinate cost related studies.
The ILS manager, who might have other responsibilities, should report directly to the project
manager and have the same level of authority as the design and manufacturing managers.
This is to ensure that logistic support issues are given equal weight in the design process. For
projects involving lower tier subcontractors and/or suppliers, a similar management structure
should apply. The subcontractor and, where applicable, supplier ILS managers should report
to the overall item contractor ILS manager in a management tier structure. When applicable,
the ILS manager should have authority to achieve effective cooperation with the customer and
with any subcontractors. Establishing an integrated team needs to be considered.
Clear terms of reference and methods of operation should be identified and agreed between
the ILS manager and the designers to ensure that supportability considerations resulting from
the LSA studies can fully influence the design. The ILS manager should understand the
design process, objectives and programme and relate the ILS programme to it. A concurrent
engineering approach is recommended with the design and logistic personnel working closely
together to evolve the design and logistic support arrangements in parallel.
