Full Description Scope This document establishes a common process and framework for measurement of systems and software. It defines a process and associated terminology from an engineering viewpoint. The process can be applied to the project and products across the life cycle. The measurement process can be applied throughout the life cycle to aid the planning, managing, assessing, and decision-making in all stages of a system or software life cycle.

Full Description Scope This document establishes a common process and framework for measurement of systems and software. It defines a process and associated terminology from an engineering viewpoint. The process can be applied to the project and products across the life cycle. The measurement process can be applied throughout the life cycle to aid the planning, managing, assessing, and decision-making in all stages of a system or software life cycle.

This document also provides activities that support the definition, control and improvement of the measurement process used within an organization or a project. This document does not assume or prescribe an organizational model for measurement.

The user of this document decides, for example, whether a separate measurement function is necessary within the organization and whether the measurement function should be integrated within individual projects or across projects, based on the current organizational structure, culture and prevailing constraints. This document does not prescribe a specific set of measures, method, model or technique.

The users of this document are responsible for selecting a set of measures for the project and defining the application of those measures across the process, products, and other elements of the life cycle.

The parties are also responsible for selecting and applying appropriate methods, models, tools and techniques suitable for the project. This document is not intended to prescribe the name, format, explicit content, or recording media of the information items to be produced. This document does not imply that documents be packaged or combined in some fashion. These decisions are left to the user of this document. The measurement process is supposed to be appropriately integrated with the organizational quality system.

Not all aspects of internal audits and non-compliance reporting are covered explicitly in this document as they are assumed to be in the domain of the quality system. This document is not intended to conflict with any organizational policies, standards or procedures that are already in place.

However, any conflict should be resolved and any overriding conditions and situations need to be cited in writing as exceptions to the application of this document. Purpose The purpose of this International Standard is to describe the activities and tasks that are necessary to successfully identify, define, select, apply and improve measurement within an overall project or organizational measurement structure. It also provides definitions for measurement terms commonly used within the system and software disciplines.

Abstract Revision Standard - Active. The measurement process is applicable to system and software engineering and management disciplines. The process is described through a model that defines the activities of the measurement process that are required to adequately specify what measurement information is required, how the measures and analysis results are to be applied, and how to determine if the analysis results are valid. The measurement process is flexible, tailorable, and adaptable to the needs of different users.

This document identifies a process that supports defining a suitable set of measures that address specific information needs. It identifies the activities and tasks that are necessary to successfully identify, define, select, apply, and improve measurement within an overall project or organizational measurement structure. It also provides definitions for commonly used measurement terms.

As a result of balloting in ISO, the statement of scope was modified as follows: "This standard describes a process for the management of risk during systems or software acquisition, supply, development, operations, and maintenance. P - IEEE Draft International Standard - Systems and Software Engineering -- Systems and Software Assurance -- Part 4: Assurance in the Life Cycle This document provides guidance and recommendations for assurance of a selected claim about the system-of-interest by achieving the claim and showing the achievement. These relations are demonstrated by means of mapping tables that show relationships between activities and tasks, and process outcomes. This mapping assists users of the edition to transition to using the edition. These process activities and tasks can be applied iteratively.
