Processes for Engineering a System
The purpose of this Standard is to provide an integrated set of fundamental processes to aid a developer in the engineering or re-engineering of a system.
TABLE OF CONTENTS Processes for Engineering a System
Chapter 6: Application Key Concepts
This Clause describes key concepts for application of the processes of Clause 4 to the engineering or reengineering of a system. There are two aspects to this clause: first, the system to which the processes are applied; and second, the top-down development of system products and the bottom-up implementation and realization of system products. The first is the basis for the system structure; the second is the basis of an engineering life cycle.
6.1 System concept
The system to which the processes of Clause 4 are applied consists of both the end products to be used by an acquirer for an intended purpose and the set of enabling products that enable the creation, realization, and use of an end product, or an aggregation of end products. Enabling products are used to perform the associated process functions of the system develop, produce, test, deploy, and support the end products; train the operators and maintenance staff of the end products; and retire or dispose of end products that are no longer viable for use. Both the end products and the enabling products are either developed or reused, as appropriate. The relationship of these system elements is shown in Figure 6.1.
Figure 6.1: System concept
| Note | The above system concept implicitly includes the personnel who develop, produce, test, operate, support, and retire the system products, as well as both those who train others involved with these system functions, and the human factors issues and concerns associated with these personnel. Such personnel and human factors... |
