In the world of Business Process Model and Notation (BPMN), clarity is king. A well-drawn diagram tells a story about how work gets done, who does it, and how information moves. However, beginners often struggle with a fundamental concept: distinguishing between the flow of control within a process and the flow of communication between different entities. This tutorial breaks down the two primary types of connectors\u2014Sequence Flow<\/strong> and Message Flow<\/strong>\u2014using a practical diagram example.<\/p>\n Before diving into the connectors, let’s look at the structure of the diagram provided. It represents a collaborative process involving two distinct participants, or “Pools.”<\/p>\n Within a single participant, the order of operations is defined by the Sequence Flow<\/strong>. This is the backbone of any business process.<\/p>\n Visual Indicator:<\/strong> A solid line with a solid arrowhead.<\/p>\n In our diagram, look at the top section inside Pool 1<\/strong>. You will see a green circle (the Start Event) connected to a yellow rectangle (a Task). The arrow connecting them is solid.<\/p>\n When a process involves multiple parties, we need a way to show that one party is communicating with another. This is where the Message Flow<\/strong> comes into play.<\/p>\n Visual Indicator:<\/strong> A dashed line with an open (hollow) arrowhead.<\/p>\n In the diagram, notice the vertical dashed line connecting the circle at the bottom of Pool 1<\/strong> to the Task in Pool 2<\/strong>.<\/p>\n Let’s trace the lifecycle of this process to see how these flows interact dynamically:<\/p>\n Understanding the difference between these two flows is critical for accurate modeling. Sequence Flow<\/strong> answers “What happens next?” inside a single unit. Message Flow<\/strong> answers “Who is telling whom what?” between different units. By correctly applying solid lines for internal logic and dashed lines for external communication, your diagrams will effectively communicate complex business interactions.<\/p>\n","protected":false},"excerpt":{"rendered":" Learn to distinguish Sequence Flow and Message Flow in BPMN diagrams to visualize internal processes versus cross-participant communication effectively.<\/p>\n","protected":false},"author":1,"featured_media":8036,"template":"","meta":{"_yoast_wpseo_title":"Mastering BPMN Flows: A Visual Guide to Sequence vs. Message Flow","_yoast_wpseo_metadesc":"Learn to distinguish Sequence Flow and Message Flow in BPMN diagrams to visualize internal processes versus cross-participant communication effectively.","inline_featured_image":false,"site-sidebar-layout":"default","site-content-layout":"","ast-site-content-layout":"default","site-content-style":"default","site-sidebar-style":"default","ast-global-header-display":"","ast-banner-title-visibility":"","ast-main-header-display":"","ast-hfb-above-header-display":"","ast-hfb-below-header-display":"","ast-hfb-mobile-header-display":"","site-post-title":"","ast-breadcrumbs-content":"","ast-featured-img":"","footer-sml-layout":"","ast-disable-related-posts":"","theme-transparent-header-meta":"","adv-header-id-meta":"","stick-header-meta":"","header-above-stick-meta":"","header-main-stick-meta":"","header-below-stick-meta":"","astra-migrate-meta-layouts":"default","ast-page-background-enabled":"default","ast-page-background-meta":{"desktop":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}},"ast-content-background-meta":{"desktop":{"background-color":"var(--ast-global-color-4)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"var(--ast-global-color-4)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"var(--ast-global-color-4)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}},"source_url":"https:\/\/www.visual-paradigm.com\/support\/documents\/vpuserguide\/2821\/286\/56998_sequenceandm.html","source_h1_title":"BPMN sequence and message flow","fifu_image_url":"","fifu_image_alt":"","_fifu_image_alt":"","fifu_alt":"","_fifu_alt":"","fifu_image_title":"","_fifu_image_title":"","fifu_input_alt":"","vp_image_hash":"8cd344de5c106995b4841e63919be53b9757be4de235f88f645b8db649dc59a0"},"asset-category":[20],"class_list":["post-8035","gallery","type-gallery","status-publish","has-post-thumbnail","hentry","asset-category-bpmn"],"source_url":"https:\/\/www.visual-paradigm.com\/support\/documents\/vpuserguide\/2821\/286\/56998_sequenceandm.html","source_h1_title":"BPMN sequence and message flow","fifu_image_url":"","fifu_image_alt":"","vp_image_hash":"8cd344de5c106995b4841e63919be53b9757be4de235f88f645b8db649dc59a0","yoast_head":"\nThe Architecture of the Diagram<\/h2>\n
