Our modeling tools provide a generic numbering mechanism that can be applied to any elements created in the modeling tool. The generic numbering mechanism allows you to:

  • Automatically assign a unique number to the elements in the model when they are created, moved, or your model is refactored.
  • Easily identify and find an element in the model when communicating with colleagues or stakeholders.
  • Show element's place in a hierarchy.

For more information about the generic numbering mechanism and how to use it, see the Generic numbering mechanism documentation.

The default numbering schemas can have two different numbering styles:

  • consecutive - this style is to number elements in one numbering level. Specify only one number part.
  • multi-level - this style is to number elements in several numbering levels. Specify at least one number part for each numbering level. Top level elements will be numbered using the first number part. Elements in subsequent levels (directly or indirectly contained in the top level element) will be numbered using successive number parts.

To learn more about the numbering styles, see Numbering Scheme property values documentation.

UAF numbering uses multi-level numbering style schema property.

UAF hierarchical numbering

Numbering of UAF motivational elements and information elements is hierarchical.

A hierarchical structure can only contain elements of the same type. Different element types cannot be mixed within the same hierarchy.

Motivational Elements:

  • Driver (prefix is D)
  • Opportunity (prefix is O)
  • Challenge (prefix is C)
  • Effect (prefix is E)

Information Elements: 

  • Operational Information (prefix is OI)
  • Resource Information (prefix is RI)
  • Strategic Information (prefix is SI)

UAF hierarchical numbering with dynamic prefixes

Numbering of UAF elements based on SysML requirements is hierarchical or dynamic (when prefix differs, numbering adapts. numbers will change, but prefixes will be kept according to elements).

A hierarchical structure can contain elements of different type. For example, Enterprise Goal and Enterprise Objective can both be in the same hierarchical structure. The same is with the Security elements.

Strategic Elements:

  • Enterprise Goal (prefix is EG)
  • Enterprise Objective (prefix is EO)

Security Elements:

  • Security Control (prefix is SC)
  • Enhanced Security Control (prefix is ESC)
  • Security Control Family (prefix is SCF)
