Section Three. Defence Equipment Acquisition and Materiel Support (DEAMS)

7 Business Overview

Clause 7.1 provides background to the business implications of MOD’s implementation of ILS. Subsequent paragraphs contain prescriptive requirements for the application of ILS. The business overview describes firstly the concept of DEAMS and then develops the importance and role of ILS throughout an equipment life cycle. The detailed components of ILS are then assembled and the specific coverage of this Defence Standard is described.

7.1 DEAMS. The conceptual DEAMS business process aims to provide and sustain equipment performance, and its availability, reliability and maintainability, at optimum LCC. Achievement of this, requires the equipment’s entire life-cycle to be managed. The ILS process within DEAMS is described in Figure 1 and is amplified below.

7.1.1Once a military need has been identified and equipment concepts to satisfy that requirement are being determined, the activity of ILS, and in particular LSA, commences. This will ensure that informed decisions are made which take into account supportability and LCC factors when equipment options are being considered.

7.1.2As the equipment concept is refined and moves through feasibility and project definition, LSA is applied in more detail. This both influences the equipment design and sustains an ongoing LCC model. As the design is refined, so are the support requirements and LCC estimates.

7.1.3ILS shall be implemented concurrently with equipment concept and design activity. As shown in Figures 1 and 2, the LSA activity shall take its inputs from design information but shall also influence that design as it progresses to achieve supportable equipment along with the associated support data. This will ensure that informed decisions are made which take into account supportability and LCC factors when equipment and system options are being considered.

7.1.4As the equipment design solution matures, the LSA sustains directly the activities to plan and provide the necessary logistic support. This prepares the ground for initial and inservice provisioning. The LSA will also define maintenance requirements which will lead directly to the creation of Electronic Documentation. The need for support and training facilities will also be determined.

7.1.5The LSA process generates data which will be stored in the LSA Record (LSAR). This Defence Standard describes the LSAR in relational data base form. The LSAR provides the information required to define the support. Some or all of this LSAR information will be maintained throughout the life of the equipment. There may be circumstances (eg for small quantities of data) where the LSAR information can be presented in other forms; specific requirements will be included in the contract.

7.1.6In-service support of the equipment will include maintenance, spares re-supply, documentation-update and continuous configuration management. In addition, data will be gathered on equipment performance and support consumption to compare with the original requirements. Support performance will be measured and the LSAR will be updated to reflect actual experience - this is referred to as maintaining a ‘hot’ LSAR. The LCC model will be updated in line with the hot LSAR.

7.1.7Actual performance will be compared with that anticipated, on a continuous basis, not only to effect in-service management actions, but also to influence decisions about follow-on procurements, eg of the same equipment or, perhaps, a different modification state (or batch) of equipment. In-service management decisions, based on the resultant predictions, may include the need to change support facilities, spares holding, maintenance skill levels, or a modification to the equipment itself. Similarly, new projects will be influenced by the results of the disciplined monitoring of previous equipment performance and costs.

7.1.8Disposal costs can be significant. ILS ensures that disposal requirements are determined and costs identified. These are considered during equipment concept and taken account of during subsequent phases. The comparison between actual and anticipated costs will be made to complete the historical record of the equipment.

7.2 Elements of ILS. For the purpose of this Defence Standard the ILS Elements are as follows:

(a)Maintenance Planning.

(b)Supply Support.

(c)Support And Test Equipment (S&TE).

(d)Reliability and Maintainability (R&M).

(e)Facilities.

(f)Manpower and Human Factors.

(g)Training and Training Equipment.

(h)Technical Documentation.

(i)Packaging, Handling, Storage and Transportation (PHS&T).

(j)Disposal (To be addressed in more detail in subsequent issues).

7.3 ILS Functions Within Def Stan 00-60. This Defence Standard identifies specific, interrelated functions, defined by their own standards and specifications profiled herein for

consistent use. This includes the fundamental function of LSA and the core ILS Elements of supply support and Electronic documentation identified above. The functions are shown in Figure 2 and described below:

7.3.1LSA. LSA, which is fully detailed in Part 1 of this Defence Standard, is conducted iteratively as part of the design process. It shall influence the design by stimulating trade-off decisions to optimize LCC. As the design matures, the role of LSA moves towards identifying the support operations and resources required for the selected design. The results are documented within the LSAR. This LSAR shall then be used to inform the concurrent procurement of the support infrastructure to meet fielding requirements. The LSAR must remain alive to design changes as the design moves into production and thus reflect the asbuilt equipment.

7.3.2The LSAR, which is fully detailed in Part 1 of this Defence Standard, records data which is used to determine the requirements for many of the ILS elements in Clause 7.2. The LSAR for the production-standard equipment shall be available for delivery as required by the contract. Finally, the LSAR will normally be kept active, comparing in-service with anticipated performance, in order to manage LCC by improving the design and/or supportability characteristics as appropriate.

7.3.3The LSAR shall be implemented in a relational database as defined in this Defence Standard, unless (exceptionally) otherwise specified in the contract.

7.3.4LSA for Software. Guidance on the application of LSA to software in equipment procurement is provided in Part 3 of this Defence Standard.

7.3.5Supply Support. The procedures for Supply Support are detailed in Part 20 of this Defence Standard. Specialist Supply Support aspects are covered in Parts 21 to 26 of this Defence Standard as follows:

7.3.5.1 The ranging requirements for initial provisioning shall be decided during the LSA programme. S2000M provides for these functions and is applicable to land, sea and air supply support procedures. Supply Support shall use this Defence Standard’s interpretation of that specification.

7.3.6 Electronic Documentation Creation and Delivery. The procedures for Electronic Documentation are detailed in Parts 10 and 11 of this Defence Standard. Information to support defence equipment comes from a variety of sources including the LSAR (for maintenance task descriptions and parts data) and also from the design activity itself (for technical drawings and other information). The range of Electronic documentation shall be prepared and delivered in accordance with the contract requirements. S1000D is a European specification for Technical Publications utilizing a common source database. Electronic documentation creation and use shall be in accordance with this Defence Standard’s profile of S1000D.

7.3.6.1 Where Technical Documentation creation and/or delivery is by means other than that prescribed within Parts 10 and 11 of this Defence Standard, the requirement will be specified within the contract.

7.4Business Interfaces Within ILS. The interfaces between the functions above are represented in Figure 2. The diagram presents the model for procuring equipment. However, in-service actions are also portrayed by recognizing that the in-service feedback influences new or revised activities in each of the ILS functions.

7.5Interfaces Outside the Current Scope of Def Stan 00-60. The integrated support processes defined in this Defence Standard have interfaces with other ILS processes and standards which do not currently have a standard MOD prescription. These include, but are not limited to: LCC modelling; equipment configuration management; equipment materiel management; spares modelling and Human Factors. Where there are specific requirements for them, they will be stated in the Contract.

7.6Quality Assurance (QA)

7.6.1QA requirements will be defined for the overall project and be set down in the terms and conditions of the contract.

7.6.2The QA requirements will apply to the ILS management, analysis and document control arrangements and be provided for in the Project Quality Plan. There will be no differentiation in the quality system employed for the design, development, engineering or logistics of the Project.

7.6.3All ILS deliverables and their design management and control shall be subject to the QA arrangements. The Contractor shall provide full traceability of analysis, data and any trade-off studies undertaken to obtain the delivered equipment support package.

7.7 Configuration Management (CM)

7.7.1 There are two inter-related aspects of CM: the CM of the equipment and the CM of the ILS elements, together with the management of the associated data. The ILS activities shall be subject to the overall CM requirements of the project and as defined under the terms of the contract.
