1.1 Purpose

The purpose of this Standard is to provide an integrated set of fundamental processes to aid a developer in the engineering or reengineering of a system.

Use of this Standard is intended to help developers

1. establish and evolve a complete and consistent set of requirements that will enable delivery of feasible and cost-effective system solutions;

2. satisfy requirements within cost, schedule, and risk constraints;

3. provide a system, or any portion of a system, that satisfies stakeholders over the life of the products that make up the system.

   Note

   The term product is used in this standard to mean: a physical item, such as a satellite ( end product), or any of its component parts ( end products); a software item such as a stand-alone application to run within an existing system (end product); or a document such as a plan, or a service such as test, training, or maintenance support, or equipment such as a simulator (enabling products).

4. provide for the safe and/or cost-effective disposal or retirement of a system.

1.2 Coverage

This Standard defines processes for engineering a system, as shown in Figure 1.2. These have been organized into five groups.

1.3 Intended applications

This Standard is intended to be applicable to the engineering or the reengineering of

1. commercial or non-commercial systems, or portions thereof;

2. any system, small or large, simple or complex, software-intensive or not, precedented or unprecedented;

3. systems containing products...
