5.3.12.1 Logistic Support Specification
Process module: Integrated Logistic Support
Responsible: Logistics Manager (when using process module Integrated Logistic Support)
Activity: Preparing Logistic Support Specification
Participating: Requirements Engineer (Supplier)
Purpose
The »Logistic Support Specification describes and refines the requirements posed on logistic support. The requirements specified in the »Overall System Specification will be analyzed and refined from a logistic point of view. In addition, operational environment, maintenance and repair activities will be recorded and examined.
Is generated by
Overall System Specification (see product dependency 4.12)
Depends on
Logistic Calculations and Analyses, Logistic Support Concept (see product dependency 5.21)
External Hardware Module Specification, Hardware Specification, External Software Module Specification, Software Specification, External Unit Specification, System Specification (see product dependency 5.23)
5.3.12.1.1 Initial Situation
Proceeding from the »Overall System Specification, the actual logistic situation will be recorded and analyzed in the initial situation. This includes, e.g., the presentation of the integration of logistics into the organizational procedures, existing devices, equipment and tools, and weak points of the current logistic support.
The operational environment and the physical loads exerted on the system during use will be described, and the requirements posed on the logistic support to be developed will be derived.
5.3.12.1.2 Logistic Requirements
This subject documents the requirements posed on logistic support. The overall picture of the requirements can be derived from the logistic requirements specified in the »Overall System Specification and the requirements derived from the subject »Initial Situation.
The required availability of the system will be specified concretely. On this basis, parameters like reliability, repairability and testability will be specified at system, segment, hardware unit and software unit level.
Type and expected frequency of the required system maintenance activities and the resulting requirements will be described. The methods for determining the activities will be presented.
General requirements posed on logistic support, which are not specific for individual resources, will be indicated, e.g., warranty policy and quality provisions.
5.3.12.1.3 Refinement of the Logistic Requirements
The requirements of the »Overall System Specification shall be allocated to »Logistic Elements and other logistic resources (e.g., special tools, measuring and test equipment). In addition, the documentation required for maintenance, repair and other support measures and the corresponding responsibilities will be allocated to logistic elements. The logistically relevant requirements shall be refined.
Exemplary Product Content
Logistically relevant requirements include the following:
- Documentations required for operation, maintenance/repair and other support measures (description, presentation, identification, development documents)
- Responsibilities for operation, maintenance/repair and other support measures (personnel strength and qualification/training requirements)
- Training infrastructure, systems, equipment and tools, e.g., defective components
- Special/standard tools, measuring and test equipment
- Spare/exchange parts, material and expendables
- Infrastructure and utilities
- Scope of storage and storage requirements (e.g., storage space, storage conditions, storage location)
- Scope of transport and transport requirements (e.g., transport volume, transport conditions)
5.3.12.1.4 Requirements Tracing
The requirements tracing allocates the logistic requirements to the refined logistic requirements, to the logistic elements and to the system and system support elements (see also Subject »Requirements Tracing in the »System Specification). The bidirectional trackability must be ensured. The allocation can be presented, e.g., by means of a matrix.
