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 assessment and demonstration, 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 Disciplines and Elements of ILS. Within a project, ILS has both an influence on and draws information from the following disciplines and related elements:

(a)Maintenance Planning.

(b)Supply Support.

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

(d)Reliability and Maintainability (R&M), Safety, Testability and other design disciplines.

(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).
