60300-3-12 © IEC:2001– 11 –INTRODUCTIONThe successful operation of a product in service depends to a large extent upon the effectiveprovision of logistic support in order to achieve and maintain the required levels of per-formance and customer satisfaction.Logistic support encompasses the activities and resources required to operate and maintain aproduct (hardware and software) in service. Logistic support covers maintenance, manpowerand personnel, training, spares, technical documentation and packaging handling, storageand transportation, support resources and disposal.The cost of logistic support is a major contributor to the life cycle cost (LCC) of a product andincreasingly customers are making purchase decisions based on life cycle cost rather thaninitial purchase price alone. Logistic support considerations may therefore have a majorimpact on product sales by ensuring that the product can be operated and supported at anaffordable cost and that all the necessary resources have been provided to fully support theproduct so that it meets the customer requirements.Quantification of support costs allows the manufacturer to define the support cost elementsand evaluate the warranty implications. This provides the opportunity to reduce risk andallows support costs to be set at competitive rates.Integrated logistic support (ILS) is a management method by which all the logistic supportservices required by a customer can be brought together in a structured way and in harmonywith a product. In essence, the application of ILS– ensures that supportability considerations influence the concept and design of a product;– develops logistic support arrangements that are consistently related to the design and toeach other;– provides the necessary logistic support at the beginning and during customer use anddisposal at optimum cost;– allows improvements in the support of a product throughout its life.The method by which ILS achieves much of the above is through the application of LogisticSupport Analysis (LSA). This is a series of support analysis tasks that are performediteratively throughout the design process in order to ensure that the product can be supportedefficiently in accordance with the requirements of the customer.The successful application of ILS will result in a number of customer and supplier benefits.These should include, but will not be limited to, some or all of the following:– meeting customer requirements;– increased overall customer satisfaction;– better visibility of support costs;– lower customer support costs;– greater product availability;– fewer product modifications due to supportability deficiencies and hence less supplierrework;SIST EN 60300-3-12:2004

60300-3-12 © IEC:2001– 13 –– better adherence to production schedules in process plants through reduced maintenanceand better support;– reduced product LCC;– lower supplier product costs;– a better and more saleable product leading to increased product purchases;– potential for purchase or upgrade of the product sooner through customer savings onsupport of current product;– improved safety;– reduced support costs providing more likelihood of repeat sales.ILS should be an integral part of the total product design and management process with anon-going improvement activity using monitoring of achieved performance to tailor existingsupport and influence future design activities.For many years, ILS was predominantly applied to military procurement, primarily usingMilitary Standard 1388, generated by the US Department of Defense (DoD). Other countrieshave also produced their own military standards that refer to specialized governmentinfrastructures and these may be unnecessarily complex for commercial application. Themethods and benefits of ILS, however, have potential for much wider application incommercial and civilian use.The idea of ILS is simple and depends on a structured procedure which ensures that theappropriate logistic aspects are considered fully throughout the design and developmentphases of a product, in close co-operation with the designers. Under an ILS approach theability to support the product effectively is given equal weight to performance and is fullyconsidered in relation to its cost.The application of ILS provides improvements in availability, maintenance support and long-term logistic cost savings. Logistic costs are significant through the life of a system and canoften amount to many times the initial purchase cost of the system.This standard is one of a series of application guides that describe various tools in the field ofmaintenance support under the generic heading of Dependability management. ILS is amanagement technique that can effectively be used to determine the support requirements ofa product.This standard provides guidance on the minimum activities necessary to implement effectiveILS for a wide range of commercial suppliers. The standard supplements IEC 60706-4 1),which emphasizes the maintenance aspects of the support requirements and refers to otherexisting standards where appropriate. The use of Reliability and Maintainability (R&M) studiesis also mentioned in this standard, as R&M analysis is an important contributor to the ILSprocess. However, R&M techniques are not described in any detail in this standard and theappropriate IEC standards should be consulted.________1)IEC 60706-4, Guide on maintainability of equipment – Part 4: Section 8: Maintenance and maintenance supportplanningSIST EN 60300-3-12:2004

The application of ILS is also applicable to largesystems, such as a power plant or a paper mill, and provides a methodology for theidentification and optimization of the support requirements for the individual products thatconstitute the plant.Logistic Support Analysis (LSA) is an analytical process that is a part of ILS and comprises aseries of analysis tasks to influence the design to improve its supportability and to ensuresupport requirements are adequately identified and provided.The degree of application of ILS and the associated LSA will vary accordingly with the degreeof design freedom, technical complexity, cost of the product and other factors.SIST EN 60300-3-12:2004

60300-3-12 © IEC:2001– 21 –In applying the principles of ILS it is necessary that the logistic support concept be tailored tomeet the specific product development and customer needs. Therefore if a product is acompletely new development it may be necessary to apply most of the LSA tasks, but where aproduct is identified as an existing item, it will not be necessary to apply all of the tasks. Thisis referred to as tailoring and should address the depth of analysis to a cost-effective levelbased on maturity and the type of product.5.3 Elements of ILSThe following elements of support are covered by ILS, and may include, but are not limited to:– maintenance planning;– support equipment (including tools and test equipment);– technical documentation;– training;– manpower and personnel;– spares/materials;– packaging, handling, storage and transportation;– software support;– facilities;– environmental aspects;– disposal.Key areas that interface with ILS are:– systems and design engineering;– reliability analysis (IEC 60812);– maintainability analysis (IEC 60706-2);– Life Cycle Cost (LCC) analysis (IEC 60300-3-3);– reliability centred maintenance (IEC 60300-3-11).In addition ILS interfaces with:– project management;– risk management;– safety and hazard analysis;– human factors analysis;– trials and acceptance;– configuration management;– quality;– environmental requirements;and will reflect and contribute to the approach in these areas.The tasks and procedures for these interface areas are covered in other IEC standards.SIST EN 60300-3-12:2004

It is usually defined within the customer profile and shouldbe provided to both the design and support team to ensure that the product will besupportable in its intended environment. As the design progresses the initial support conceptwill be confirmed and expanded.Box 2 of figure 1 provides basic design and performance information. The design information isprogressively analysed in terms of its support implications under the LSA in clauses 7 and 8.Reliability and maintainability characteristics and Fault Mode and Effects Analysis (FMEA) area fundamental input to these analyses. The R&M characteristics indicate the likelihood ofproduct failure and time to restore and hence the maintenance and support effort andresources required.The FMEA indicates the likely causes of failure of the product and provides feedback toimprove the design. The FMEA for the final design and support concept provides the input forthe systematic identification of all the maintenance and support resources required for theproduct through the use of maintenance support analysis described in clause 9.Proving trials will normally be conducted on new products to demonstrate stated performanceor fitness for purpose and the trials should include the logistic support arrangements. Thetesting of the design and proving of the support arrangements are covered under trials andlogistic support (see clause 10). This ensures that the recommended support is sufficient tomeet the required performance.SIST EN 60300-3-12:2004

60300-3-12 © IEC:2001– 25 –5.5 Logistic Support Analysis (LSA)LSA comprises a series of analysis tasks that are selected, or tailored, as necessary to meetthe requirements of the product.

The CP&S constraint is the framework of how the productshould be supported: for example, customer or supplier repair capability, the skill level oftechnicians, available facilities. These all have a bearing on the complexity of anymaintenance tasks that can be performed.In clause 7, use is made of support experience and data on previous products in early designphases to understand and build up a picture of where the support drivers may be for the newproduct and to prompt changes to improve availability and reduce life cycle cost. Design andsupport options that are not favourable are discounted and favourable options areprogressively detailed and subject to a more detailed analysis (clause 8). Life cycle costinganalysis (box 5 of figure 1) and Level Of Repair Analysis (LORA) are used as quantitativetechniques to compare options and may also be used to provide predictions of long-termcosts to assist customers with future financial planning or the identification of warranty costsand decide on the optimum level of repair in a given application. The results in terms ofrecommendations and requirements for the best support solution are fed back into the designstudies (box 2 of figure 1) and reflected in design documentation. In some circumstances, theresults of the LSA may cause the support concept to be modified.The various LSA studies are described in subsequent clauses of this standard.IEC

60300-3-12 © IEC:2001– 27 –5.6 LSA databaseThe LSA database provides the mechanism and repository for the LSA and documents thedetailed support to be provided as a result of the clause 9 tasks. To maximize the benefit, theoutputs and results of the LSA should be recorded in a controlled and structured LSAdatabase. The creation of an electronic LSA database is recommended as the most viablemeans to store and control the information obtained. This is discussed further in clause 11.6 Planning and management of ILS6.1 GeneralThe planning and management of ILS addresses the programme of work required to carry outthe ILS tasks. For a complex product this is a major factor in the success of the ILSprogramme. The planning of ILS should ensure that all ILS and LSA tasks, responsibilitiesand internal and external interfaces at each phase of the design are clearly defined. The ILSmanagement and planning tasks are listed below.– Determine and agree on ILS responsibilities, including logistic information, and interfaceswith the customer and the product design team.– Define programme of LSA tasks to be undertaken (see clauses 7, 9 and 11).– Determine method for providing design guidance.– Define logistic support resource outputs.– Plan and put in place review processes, both informal and formal, to audit the design andthe ILS programme.– Produce and maintain ILS planning documentation to control the ILS programme.– Monitor and control the ILS programme of work.– Identify risks associated with the ILS programme and propose actions to reduce theserisks.6.2 Management structure and responsibilitiesA single person, usually referred to as the ILS manager, should be appointed withresponsibility for the overall programme of ILS tasks. The responsibilities of the ILS managerare the ILS management and planning tasks defined in 6.1 and other detailed tasks asallocated. The principal tasks of the ILS manager are to:– meet the requirements of the ILS/LSA plans;– develop the support-related technical characteristics of the product;– co-ordinate and integrate inputs from the specialist disciplines;– co-ordinate logistic support provided by contractors and subcontractors.The ILS manager, who may have other tasks, should report directly to the product or projectmanager and have the same level of authority as the design and manufacturing managers.This is to ensure that support issues are given equal weight in the design process.SIST EN 60300-3-12:2004

60300-3-12 © IEC:2001– 29 –For projects involving lower tier subcontractors and/or suppliers, a similar management struc-ture should apply. The subcontractor and, where applicable, supplier ILS managers shouldreport to the overall product contractor ILS manager in a management tier structure. Whenapplicable the ILS manager should have authority to maintain effective liaison with thecustomer and with any subcontractors.Clear terms of reference and methods of operation need to be identified and agreed betweenthe ILS manager and the designers to ensure that supportability considerations resulting fromthe LSA studies can fully influence the design. The ILS manager needs to understand thedesign process, objectives and programme and relate the ILS programme to it. A concurrentengineering approach is recommended with the design and logistic personnel working closelytogether to evolve the design and support arrangements in parallel.The ILS manager may have a team of specialists in LSA, R&M, LCC and logistic supporttechniques. The number of specialists required will depend upon the size of the project andprogramme of work and they would assist the ILS manager by performing detailed tasks asdirected in the ILS/LSA plan.6.3 Controlling documentation and review processes6.3.1 Planning documentationIt is recommended that a product ILS plan be produced which will be updated for each phase.This should define the ILS programme tasks to be completed, as selected in the tailoringprocess, and the management controls to be put in place for the success of the programme.The ILS plan should be sufficiently detailed to ensure a clear understanding of the variousmanagement responsibilities, objectives and aims of the programme, the LSA studies to becompleted and supportability outputs to be produced. The ILS plan may be supported by anumber of element planning documents, for example, R&M plan or LSA plan. These can beissued separately or, more beneficially, annexed to the ILS plan to provide improved visibilityof the total set of planning requirements. The number and content of plans should be limitedto those required to adequately control the ILS programme.6.3.2 Review proceduresReviews are a fundamental part of ILS management.At all major design reviews ILS should be identified as an agenda item, in which the ILSmanager should summarize the current findings and results of the ILS programme tasks. Thepresentation of the design should also discuss any impact on supportability and logisticsupport provision from the design studies and trade-offs which have been performed.ILS reviews should also be held at key stages in the programme to discuss and review thedetailed results and progress of the various activities, for example, LSA, R&M, LCC. Theseshould be timed to occur a few weeks before the scheduled design reviews. Furtherinformation on design reviews is given in IEC 61160.SIST EN 60300-3-12:2004

60300-3-12 © IEC:2001– 31 –6.3.3 Identification of supportability issuesSupportability is the degree to which product design characteristics and planned logisticsupport resources meet product operational utilization requirements. To provide a furthermanagement tool for ensuring that supportability and any other design related issues arehighlighted in a project, it is recommended that a procedure be introduced to document issuesand risks. These would be monitored by the product team through actions to investigate andmitigate the issues/risks.7 Customer profile constraints and supportability factorsThe purpose of the customer profile constraints and supportability factors LSA tasks is toidentify the customer’s constraints and goals for logistic support. Annex A contains illustrativeexamples of LSA tasks.7.1 Customer profile constraintsThe application of ILS will vary to some extent with each type of product, depending on theway it is operated and maintained, and the relationship of the manufacturer to the customer.There are a number of different scenarios where ILS may be applied, ranging from a productdeveloped specially for a customer to meet a particular requirement, to a domestic product wherethe ultimate customers are the public at large who have no direct link with the productmanufacturers. In all cases, the ILS process will be largely similar but it is important that a fullunderstanding is established of how the product is intended to be used and the variousconstraints under which it is likely to be operated and maintained.In each case, it is the manufacturer who initiates the ILS activities and who has to apply theresults of the analysis to produce a recommended support policy and infrastructure tomaintain the product in the condition that will enable it to carry out its function. The customermay play an active part in establishing the support structure where the product is a uniquedevelopment to a particular requirement. At the other end of the scale, the customer mayhave no input to that process, as in the case of the domestic product which is serviced andmaintained by a separate repair organization. Here, the LSA will enable the maintenanceprocedures to be established and the necessary tools and test equipment to be provided tothe repair agents.Ideally, a full understanding of how the product is intended to be used and the variousconstraints under which it is likely to be operated and maintained needs to be established or ageneral set of assumptions defined. The information may be derived from suppliers' customerrecords and/or market research, or by visits to existing or potential customer’s operation andmaintenance facilities.Studies need to be made on the use and application of the proposed product to obtaininformation such as:– operating cycle, including number of operating days or cycles per unit of time;– safety requirements;– number of products to be supported;– number of customer sites and maintenance levels;SIST EN 60300-3-12:2004

60300-3-12 © IEC:2001– 33 –– availability and/or repair/resupply time requirements;– allowable periods for undertaking maintenance;– commonality with other customer systems and equipment:– effect of product use on the environment;– definition of the product operational and storage environment;– likely numbers, competence and skill of operators and maintenance personnel;– transportation considerations, for example, mode, type, quantity to be transported,destinations, transport time and schedule;– service and design life;– any other relevant use-related constraints.Some of this information may not be available but will be determined in the analysis process.For example, where the product will be on sale to the public through retail outlets, themanufacturer will need to consider setting up a servicing organization, if it does not alreadyexist, to provide a repair facility to the customers. For this it is necessary to establish thelocations and levels of support required and it is therefore important that the information is asaccurate as possible, as the output of the LSA will provide the scale of the supportorganization required, the cost of which could be a significant factor in the financial viability ofthe product.The data collected would be used as a common reference for design, reliability and maintain-ability analysis, performance assessment, and definition of the environmental envelopetoensure consistency of analysis. An example is shown in table A.1.The customer profile constraints report is produced to define how a product is, or will be, usedand supported. It provides the basic information to the design team about the existing supportorganization. The report may be provided by the customer to describe his own supportorganization, or may be generated as part of a market survey to detail what will be available,or expected to be provided, within a particular market area. If applicable, for example, forprocurement of large systems or plant, the report should be checked by the customer andshould also be provided to subcontractors and/or suppliers for information and agreement.7.2 Supportability factors7.2.1 Logistic support standardizationLogistic support standardization refers to the use of existing and planned supplier andcustomer support resources, the re-use of existing hardware and software modules in the newproducts, and the development of common design and support solutions for different elementsof a new product. Appropriate standardization may– substantially reduce life cycle cost;– minimize the need to introduce new support resources;– or minimize the need to modify existing ar
