Title

SV-8 Systems Evolution Description Subview

Version & Date

Introduction

The SV-8 subview is part of the DNDAF System View.

The System View-8 (SV-8): Systems Evolution Description represents systems evolution over time.

Purpose

The SV-8, when linked together with other evolution sub-views such as the SV-9 and the TV-1, provides a clear definition of how the architecture and its systems are expected to evolve over time. In this manner, the SV-8 can be used as an architecture evolution project plan or transition plan.

Background

The SV-8 provides a transition plan to evolve a system or family of systems over time. This plan may accommodate changes to the scope and capabilities of a system, or changes to the technical components that enable or support more efficient/effective functionality.

Description

Definition

The Systems Evolution Description captures evolution plans that describe how the system, or the architecture in which the system is embedded, will evolve over a lengthy period of time. Generally, the timeline milestones are critical for a successful understanding of the evolution timeline.

Detailed Description

The SV-8 describes plans for modernizing system functions over time. Such efforts typically involve the characteristics of evolution (spreading in scope while increasing functionality and flexibility) or migration (incrementally creating a more streamlined, efficient, smaller, and cheaper suite) and will often combine the two thrusts. This sub-view builds on other sub-views and analyses in that planned capabilities and information requirements that relate to performance parameters of SV-7 and technology forecasts of SV-9 are accommodated in this sub-view.

This sub-view is supported by, and should be consistent with, the requirements defined in the operational views as well as the forecasts documented in the System Technology Forecast (SV-9) and Standards Profile (TV-1) sub-views.

Presentation

any suitable means of showing time progression

From section 3.22.7, volume 2:

The SV-8 can be represented using two generic templates: system evolution and system migration. If the architecture describes a communications infrastructure, then a planned evolution or migration of communications systems, communication links, and their associated standards can also be described in this sub-view.

Prerequisites

The SV-1 and SV-7 are the prerequisites for this sub-view:
SV-1. Defines the systems under consideration. It sets the scope for this sub-view

SV-7. Systems Evolution Description uses the Systems Performance Parameters.

Comments

The DNDAF does not have a view nor subviews concerned with the acquisition/procurement of systems via projects by which time could otherwise be introduced.
