<h2>Behavioural Diagrams</h2>
<h3>Use case Diagram</h3>
<p>(From TOGAF) A Use-Case diagram displays the relationships between consumers and providers of Business/Application services.</p>
<p>Services are consumed by actors or other services and the Use-Case diagram provides added richness in describing business capability by illustrating how and when that capability is used.</p>

<h3>Flow Charts (BPMN)</h3>
<p>Also called Process Flow Diagrams, Activity Diagrams (UML), and Swimlane Diagrams, Business Process Modeling Notation (BPMN) is a flow chart method that models the steps of a planned business process from end to end.</p>
<p>Flow charts may utilize swim-lane techniques to represent ownership of process steps and typically include controls, triggers and sub-processes.</p>

<p>Flow charts can also be modelled from the perspective of a user in UX/UI, via:</p>
<ul>
<li>Customer Journey Maps</li>
<li>Task flows</li>
<li>Wireflows</li>
</ul>
<h3>Sequence Diagram</h3>
<p>A Sequence Diagram visualises the interactions between objects for a given scenario, in sequential order.</p>
