11、rd has received approval for Publication. prEN 9320:2013 (E) 4 1 Scope These general guidelines cover the open system acquisition and supply processes. There is an increasing requirement for systems designed and produced by industry, particularly in the aeronautic, space and defence fields, to be us

12、ed with other systems designed, produced, acquired and operated independently. The concept of open systems is touched upon in many systems engineering documents. This document deals specifically with this subject. To this end, through the various processes applied, it provides information to stakeho

13、lders (buyers, suppliers, designers, subcontractors, supervisors, etc.) on the best practice to be adopted. The specific nature of openness for a system is defined by all the following properties: Interchangeability, Interoperability, Upgradability, Reusability, Reversibility, Flexibility, Affordabi

14、lity. These properties are defined in the glossary for these general guidelines. These general guidelines are largely based on the structure and system life cycle processes described in standard ISO/IEC 15288:2008. The characteristics of openness also relate to: The products or services offered by t

15、he company (target systems resulting from use of company processes). The companys processes (project systems). Several stakeholders, with their own assignments, cultures, jobs and geographical locations, different working methods, modelling frameworks, standards, tools and aids, etc. are involved in

16、 the activities, which are sometimes multidisciplinary, of the internal and external processes of a company. These diverse elements are not necessarily all suited to working together without causing certain risks, a loss of autonomy, effectiveness and/or efficiency, etc. A company must, for example,

17、 develop its ability and capacity in terms of interoperability both internally (between the systems of which it is made) and externally (with other partners), including, by way of an example: Ability of each stakeholder and each department involved to maintain efficient and trusting relationships wi

18、th other stakeholders, taking into account deadline, cost and quality objectives, Ability to exchange, communicate and use the necessary flows (data, information, knowledge, materials, energy) autonomously, without error and dynamically throughout the life cycle of the target system, Ability to coor

19、dinate, synchronise and manage common tasks and share and use resources (human, machine or application) and services efficiently and appropriately. prEN 9320:2013 (E) 5 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensa

41、and consumers of systems, which may make products or perform services. These systems are produced by some or implemented or consumed by others within the context of the relationship between buyers (those who purchase and consume or use) and suppliers (those who produce and sell). Buyer/supplier rela

42、tions are maintained through contracts. Acquisition of an open system requires specific activities to be carried out to optimise signature of contracts to obtain a product/service that satisfies the openness requirements. The purpose of the process described in this chapter is to characterise these

43、activities. The level of detail of each activity depends on the complexity of the system to be acquired. 4.1 An acquisition strategy is established 4.1.1 Define an openness strategy Define the openness level required depending on, for example, the maturity scale defined using the SCOPE model develop

44、ed by the NCOIC. To establish this openness level, it is important to: Be aware of the operational environment into which the system to be acquired will be integrated, exhaustively and explicitly identify the systems of the operational environment with which the system to be acquired should interope

45、rate, characterise the flows between these systems. List the rules and standards applied by the technical systems of this operational environment. prEN 9320:2013 (E) 9 Define the openness objectives. Rate these openness objectives for the system to be acquired in accordance with the environment. 4.1

46、.2 Define an acquisition strategy The way in which the system is acquired (related to the quantity and/or the complexity of the system in question) can have a direct effect on the system openness. A short-term acquisition for a system with a short life cycle may be unique. On the other hand, acquisi

47、tion in stages or long-term acquisition for a system with a long life cycle entails requirements in terms of openness, including upgradability, and can cause openness problems linked to changes in the environment in which it is integrated, for example unplanned changes to the other systems in its en

48、vironment. It is therefore necessary to establish an acquisition strategy depending on the system life cycle model and the changes anticipated in the system environment (regular upgrades, midlife upgrades, etc.). It is necessary to: Define the life cycle model. The more important the openness charac

49、teristics, for example interoperability, the more complex the systems life cycle will be. Describe the acquisition increments leading to the solution. The acquisition increments must be organised depending on the openness requirements identified (for example planning the main changes anticipated taking into account the maturity of the technology implemented TRL). Contractual requirements specific to reversibility will be defined when the acquisition strategy is defined. 4.1.3 Defin
