| “Where does UML fit?” is a common question among new (and not so new!) business analysts. We all know that the M stands for modelling but beyond this, perceptions start to differ. In its current form (V2.0) UML consists of 13 diagram types all of which provide a different view of a system.

| Many people on our Business Analysis workshop ask why we use dataflow diagrams (DFDs). Why not Use Case…or even BPMN? After all DFDs have been around for 20 years, surely the world has moved on?

(1145 Views)
( 0 Comments)
| In the Unified Modeling Language (UML), use cases are visually represented as ellipses. However, in spite of its popularity and size, UML has little of practical use to offer modelers beyond this simple iconic representation. Trying to capture and present requirements using just use case diagrams can often render the otherwise useful technique of u... |
