the demonstration of an actual system prototype in an
operational environment, such as in a command post

Technology Readiness Level Description
SW: Actual application of the software in its final form
and under mission conditions, such as those encoun
tered in operational test and evaluation. In almost all
cases, this is the end of the last “bug-fixing” aspects
of the system development. Examples include using
the system under operational mission conditions. Soft
ware releases are production versions and configura
tion controlled. Frequency and severity of software
deficiencies are at a minimum.

Building the IT Portfolio
INTRODUCTION
Overview
There is no single best practice for building or improving the IT portfolio. IT portfolio management is a fluid and dynamic process of trying to create and maintain the perfect homeostasis between optimizing capacity and demand against a series of criteria and constraints whereby:
• New discovery initiatives and projects are evaluated, selected, and prioritized
