Comments

The definition in v3.1 doesn’t actually define what a system is only that if you use an artefact as one within a Capability Configuration it is a ‘system’.

This gets to be quite confusing as the stereotype ‘System’ exists independently of Capability Configuration i.e. it is still used to represent a System. As defined it seems that you can only define a system through the combination of using the ‘System’ stereotype and defining it’s usage context.

Note that in version 3.1 as a Resource, System can have a Function and can interact.

NATO AF v3.1, Chapter 5, 5.2.6.1 p116 - definition of Capability Configuration...

... a system cannot contribute alone (it must be hosted on a physical asset or used by an organisational resource or both).

Covered by NATO release conditions.

This means that NAF::System cannot include people (Human Resource) - people are always external to a system. A system in NAF cannot provide any capability nor can NAF be used for a soft system. This is very different to TRAK::System.

As defined in NAF 3.1:

  • system is something physical
  • it is not a soft system
  • it can’t contain anything else like Organisation, Post or Role, or Software
  • systems cannot provide capability

It is very similar to the definition and use of System in MODAF.

This is quite different from the definition of TRAK::System which isn’t defined as a product or artefact and can include people.
