Title

SV-7 Systems Performance Parameters Matrix Subview

Version & Date

1.6 See DNDAF Release History

Introduction

The SV-7 subview is part of the DNDAF System View.

The System View-7 (SV-7): System Performance Parameters Matrix evolves with System Data Exchange Matrix (SV-6) to depict the current performance characteristics of each system, and the expected or required performance characteristics at specified times in the future.

Purpose

One of the primary purposes of SV-7 is to communicate which crucial characteristics are considered for successful achievement of the mission goals assigned to the system. These particular parameters can often be the deciding factors in acquisition and deployment decisions, and will figure strongly in systems analyses and simulations done to support the acquisition decision processes and system design refinement.

Background

The System View-7 (SV-7): System Performance Parameters Matrix evolves with System Data Exchange Matrix (SV-6) to depict the current performance characteristics of each system, and the expected or required performance characteristics at specified times in the future.

Description

Definition

The Systems Performance Parameters Matrix specifies the quantitative characteristics of systems and system hardware/software items, their interfaces (system data carried by the interface as well as communications link details that implement the interface), and their functions. It specifies the current performance parameters of each system, interface, or system function, and the expected or required performance parameters at specified times in the future.

Detailed Description

The SV-7 builds on SV-1, SV-2, SV-4, and SV-6 by specifying performance parameters for systems, systems hardware and software items, systems interfaces (defined in SV-1), communications details (defined in SV-2), systems functions (defined in SV-4), and systems data exchanges (defined in SV-6). In addition, performance parameters often relate to a system function being performed. Therefore, system functions and their performance attributes may also be shown in this sub-view. If the future performance expectations are based on expected technology improvements, then the performance parameters and their time periods should be coordinated with a Systems Technology Forecast (SV-9). If performance improvements are associated with an overall system evolution or migration plan, then the time periods in SV-7 should be coordinated with the milestones in a Systems Evolution Description (SV-8).

Presentation

  • table/matrix

From section 2.22, volume 4:

...

This sub-view is built as a two-dimensional table with multiple nested column and row headers. The purpose of this table is to record the parameters of all the systems that participate in SV-1 and SV-2. These parameters are partitioned into hardware and software ones and are measured at three different time intervals: current/actual, intermediate, target/desired.

Examples

See:

  • p121 Figure 3.21.1 in DND/CF Architecture Framework (DNDAF)  Volume 2: DND/CF Views and Sub-Views

Prerequisites

The SV-1 is the prerequisite for this sub-view:

  • SV-1. Defines the systems under consideration. It sets the scope for this sub-view
