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 used 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 stakeholders (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@ - Affordability. 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 the company (target systems resulting from use of company processes). -The company's 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 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@ 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 with 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 coordinate@ synchronise and manage common tasks and share and use resources (human@ machine or application) and services efficiently and appropriately.
