# Process Designer Component A process designed within the **Process Template Diagram** consists of multiple interconnected components that collectively define the execution flow of a business process. In ONEWEB **Process Designer**, a process may include the following key components: * **Activity Nodes** * **Start and End Events** * **Gateways** * **Boundary Events** * **Pools and Lanes** Each of these components serves a specific purpose within the process flow and is modeled using **BPMN (Business Process Model and Notation)** standards. *** ### Main Process Components Overview #### Activity Nodes Activity Nodes represent **units of work or execution steps** inside a process.\ Examples include: * Human Tasks * Database Tasks * Service or System Tasks Each activity node is designed to fulfill a specific business objective, such as user interaction, data processing, or system integration. *** #### Start and End Events * **Start Events** define where and how a process begins * **End Events** define how and when a process is completed These events mark the boundaries of the process lifecycle. *** #### Gateways Gateways control **decision‑making and branching logic** within the process. They are used to: * Split process flows based on conditions * Merge multiple execution paths * Control parallel or exclusive execution *** #### Boundary Events Boundary Events are attached to activity nodes and are triggered by specific conditions such as: * Timeouts * Errors * Exceptions They provide mechanisms for handling alternative flows or exceptions without interrupting the main process structure. *** #### Pools and Lanes Pools and Lanes help organize activities by **roles, responsibilities, or organizational units**. * **Pools** represent a participant or system * **Lanes** represent subdivisions (e.g. roles or work parties) They improve readability and clarify ownership within complex process diagrams. *** ### Component Details The detailed explanation of **each Activity Node**, available in the **Activity Panel**, including: * Its purpose * Configuration options * Usage guidelines …is described in the following sections. > Please refer to the **Activity Nodes** section for a detailed breakdown of each node type and its functionality. *** ### Summary The Process Template Diagram is composed of structured BPMN components that together define the behavior and execution logic of a business process. Key points: * Processes are built using standardized BPMN elements * Each component has a distinct role in execution * Proper use of components improves clarity and maintainability * Understanding these components is essential before designing complex workflows This section serves as a foundation for exploring individual **Process Designer components** in detail. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
