Business Process Elements: Activities

The vector stencils library "Activities" contains 35 symbols for drawing business process diagrams (Business Process Model and Notation) using the ConceptDraw PRO diagramming and vector drawing software.
"An activity is represented with a rounded-corner rectangle and describes the kind of work which must be done. 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). Sub-process. Used to hide or reveal additional levels of business process detail. When collapsed, a sub-process is indicated by a plus sign against the bottom line of the rectangle; when expanded, the rounded rectangle expands to show all flow objects, connecting objects, and artifacts. Has its own self-contained start and end events; sequence flows from the parent process must not cross the boundary. Transaction. A form of sub-process in which all contained activities must be treated as a whole; i.e., they must all be completed to meet an objective, and if any one of them fails, they must all be compensated (undone). Transactions are differentiated from expanded sub-processes by being surrounded by a double border. Call Activity. A point in the process where a global process or a global Task is reused. A call activity is differentiated from other activity types by a bolded border around the activity area." [Business Process Model and Notation. Wikipedia]

This BPMN (Business Process Model and Notation) diagram sample represents the taxi service order procedure workflow.
"A business process or business method is a collection of related, structured activities or tasks that produce a specific service or product (serve a particular goal) for a particular customer or customers. It often can be visualized with a flowchart as a sequence of activities with interleaving decision points or with a Process Matrix as a sequence of activities with relevance rules based on data in the process. ...
There are three types of business processes:
(1) Management processes, the processes that govern the operation of a system. Typical management processes include "corporate governance" and "strategic management".
(2) Operational processes, processes that constitute the core business and create the primary value stream. Typical operational processes are purchasing, manufacturing, advertising and marketing, and sales.
(3) Supporting processes, which support the core processes. Examples include accounting, recruitment, call center, technical support. ...
The ... improvement areas are equally applicable to policies, processes and detailed procedures (sub-processes/ tasks). There is a cascading effect of improvements made at a higher level on those made at a lower level.
For instance, if a recommendation to replace a given policy with a better one is made with proper justification and accepted in principle by business process owners, then corresponding changes in the consequent processes and procedures will follow naturally in order to enable implementation of the policies" [Business process.
