Please support thie ability to build Quality Attibute Scenarios. This would enable the architects to define Stimulus-response model to capture or define the Quality Attribute Scenarios with "Stimulus Source or Actor", "Stimulus", "Artificat", "Environment", "Response" and "Response Measure".
Also, while realizing this feature the "Response Measure" can be represented with icons such as a clock that indicates it captures the time behaviour etc as value addition.
Refer Figure 3 : Parts of a quality attribunate scerio. for an sample reference.
Please do give high priority for this request as this would help many architect / designers and would be great value addition for this tools capability.
