NCOIC has defined a comprehensive set of core and extended attributes of net-centric systems and published three key attribute and measurement tools: the Core Net-centric Principles, SCOPE Model and Network Centric Analysis Tool.

Core Net-centric Principles
NCOIC established its Core Net-centric Principles in 2008 to provide guidance in simplifying the task of identifying attributes and characteristics of net-centricity and systems supporting net-centric operations and environments. The motivation for developing these principles came from a request from the U.S. Department of Defense Office of Networks and Information Integration to review its net-centric attribute checklist. In the process of reviewing the attributes, a set of common and underlying principles were identified:

  • Explicitness - An entity should make all information about itself explicit
  • Symmetry / Reciprocal Behavior - Relationships among networked entities should exhibit symmetric characteristics and behaviors
  • Dynamism - Networked entities should support dynamic behaviors
  • Globalism / Universality - There should be no bounds on the scope of applicability
  • Omnipresent / Ubiquitous Accessibility - Entities should have omnipresent or ubiquitous access to resources
  • Entity Primacy - Entities have identity distinct from contexts in which they participate
  • Manage Relationships - Relations should be explicitly represented and provide for negotiation, creation, change and termination
  • Open World - There is incomplete knowledge of the operational environment
  • Pragmatism - The ability to improve operational effectiveness is paramount

SCOPE Model

The Systems, Capabilities, Operations, Programs and Enterprises (SCOPE™) model is an analytical tool that helps to characterize systems and organizations along interoperability dimensions. This tool assists customers and developers in understanding gaps to be overcome and strengths to be leveraged. The word “model” refers to an analytical methodology that helps participants understand the dimensions of net-centric operations and derive requirements for interoperability. SCOPE is important because it helps customers arrive at methodology and standards for the emerging network-centric operations technologies that actually work. And it forms a basis for conducting NCAT assessments that provide quantitative metrics.

SCOPE gives customers and companies the means to characterize interoperability requirements for net-centric systems, including:

  • How isolated or connected are the systems to each other?
  • How isolated or connected are the systems to their environment?
  • What are the intended purposes of the connection between systems?

Network Centric Analysis Tool
The Network Centric Analysis Tool (NCAT™) is an assessment tool that provides a metric-based approach to evaluate and measure the “fitness” of a system architecture for operating in a net-centric environment. NCAT is focused on criteria, categories, compliance and recommendations.

NCAT was designed to help organizations assess compliance with specific architecture guidelines and reference models, select appropriate architectures, make comparisons between similar entities being assessed and implement SCOPE analyses.

The tool provides confidence that a system can operate in a net-centric environment. The tool can also be used for: internal program self-assessment; product evaluation or ranking similar products based on scoring results; monitoring progress against plan and record achieved behaviors; verifying net-centric compliance; and selecting system / products based on assessment results.

NCAT highlights…

  • Criteria and metrics to measure “goodness” are identified
  • Helps identify how well the target system is aligned with the areas of compliance
  • Criteria can be grouped together into common categories (e.g., information assurance)
  • Criteria can be tailored to meet specific needs
