"Event partitioning is an easy-to-apply systems analysis technique that helps the analyst organize requirements for large systems into a collection of smaller, simpler, minimally-connected, easier-to-understand ‘mini systems’ / use cases. ...
Defining requirements.
Single process in a fictitious hotel using data flow diagram notation.
Single use case in a fictitious hotel using use case diagram notation.
This approach helps the analyst to decompose the system into ‘mentally bite-sized’ mini-systems using events that require a planned response. The level of detail of each response is at the level of ‘primary use cases’. Each planned response may be modelled using DFD notation or as a single use case using use case diagram notation.
The basic flow within a process or use case can usually be described in a relatively small number of steps, often fewer than twenty or thirty, possibly using something like ‘structured English’. Ideally, all of the steps would be visible all at once (often a page or less). The intention is to reduce one of the risks associated with short-term memory, namely, forgetting what is not immediately visible (‘out of sight, out of mind’). ...

Enterprise Architecture Diagrams solution extends ConceptDraw DIAGRAM software with templates, samples and library of vector stencils for drawing the diagrams of enterprise architecture models.
The vector stencils library "Business process BPMN 1.2 (Rapid Draw)" contains 12 symbols of objects, roles swimlanes, and task icons for creating the business process diagrams using the ConceptDraw PRO diagramming and vector drawing software.
"BPMN models consist of simple diagrams constructed from a limited set of graphical elements. For both business users and developers, they simplify understanding business activities' flow and process. BPMN's four basic element categories are:
(1) Flow objects.
Events, activities, gateways.
(2) Connecting objects.
Sequence flow, message flow, association
(3) Swim lanes.
Pool, lane.
(4) Artifacts.
Data object, group, annotation.
These four categories enable creation of simple business process diagrams (BPDs). BPDs also permit making new types of flow object or artifact, to make the diagram more understandable. ...
Task.
A task represents a single unit of work that is not or cannot be broken down to a further level of business process detail without diagramming the steps in a procedure (which is not the purpose of BPMN)." [Business Process Model and Notation. Wikipedia]
The shapes example "Design elements - Business process BPMN 1.2 (Rapid Draw)" is included in the Business Process Diagram solution from the Business Processes area of ConceptDraw Solution Park.
