There are two ways to assign a strength value to some of the ArchiMate relations. One is assigning a quantitative value via a profile, the other one is assigning a value using a visual sign.
On this page:
Setting a strength value via a profile
The ArchiMate realization, influence and serving relations may be assigned a quantitative strength value. This strength is for example used in analyzing the contribution of projects to strategic goals. The strength value can be set by using the Strength profile that is available with the respective relations.
Strength profile for realization relation
To set the strength of a relation using the profile:
- In the view, select the relation line of a realization, influence or serving relation.
- In the relation's Properties window, on the Profile tab, select the Strength check box.
- Click the Properties tab, expand the Strength section.
- Double click the strength (quantitative) property, type the desired value and click OK. You can also single-click the property, press F2, and then type the value.
Setting a strength value using a visual sign
For an influence relation, it is possible to indicate its strength in a model to express whether the influence is positive or negative, and how strong the influence is. By default, the influence relation models a contribution with unspecified sign and strength.
Example of influence strength of one element on other elements
To set the strength of an influence relation:
- In the view, select the relation line, and then click the +/- symbol next to the line repeatedly until the desired value is displayed: , , , , unspecified.
