Introduction

Over the past 20-years, the Department of Defense (DoD) has had the goal of evolved from being “platform-centric” to becoming “network-centric” (net-centric).

The enabling technology for the net-centric concept is Quality of Service (QoS)

Networked systems are causing people to loose contact The cloud is made out of peoplePersonnel structures are more distributed as “matrixed” organizations and “virtual” teams.How are the people in the “cloud” going to be selected, trained or promoted?

Theoretical Framework and Enabling Concepts

QoS

Technical or Social

The stated intent of the net-centric concept is to have systems and organizations that are built around human and organizational behavior.

The stated goal is to change human and organizational behavior through technology

Problem

The net-centric concept requires that all of the data be visible and available to the users

Some of the system’s data and all of the system’s knowledge is in the users’ heads.

It there a way to find out what the users know?

Approach

Assess current systems to determine if it is currently possible to locate knowledge on a network.

Develop a method that provides progress toward that goal.
