How to create UML use case diagrams

UML use case diagrams show all of the ways an end-user interacts with your systems, with all of its pre- and post-conditions, exceptions and alternate paths. These diagrams are used to establish your system requirements, whether that be a software system or an interaction with another person or team.

SysML vs UML - what's the difference?

Systems modelling language (SysML), is an extension of UML that has been modified for systems engineering. While both can document software, information and processes, SysML diagrams also document the hardware, humans, physical components, and facilities in the system.

Draw a UML state machine diagram

The concept of state diagrams or state machine graphs has been around since the mid 1900s, long before David Harel modified them into the form used today as part of the UML standard.

Create a sequence diagram

Sequence diagrams show the order of messages that are passed between elements of a system to complete a particular task or use case. The events that cross system boundaries are used by objects and people (actors) to complete their processes.

What's the difference between diagrams, charts and graphs?

Have you been asked to create a chart, a diagram, or a graph? There is a lot of confusion around these overlapping terms, especially as they are most often used interchangeably. However, there are some minor differences in how they are used.

Ishikawa diagrams for root cause analyses

Ishikawa diagrams, also called fishbone, herringbone or cause and effect diagrams, are used to analyse and identify the root causes of defects or negative events. As most problems have multiple causes, Ishikawa diagrams are a useful prompt to look at the many different contributing factors.

Complex diagramming on an online whiteboard

Many people prefer a minimal interface for diagramming, as there are fewer distractions. While online whiteboard applications often have a limited set of available tools, diagrams.net lets you use its advanced features in a less cluttered diagram editor theme.

How to use sketch.diagrams.net as an online whiteboard

This diagrams.net Sketch editor theme has an endless whiteboard-style canvas and is ideal to use as a collaborative online whiteboard with your remote team. The lack of page and grid lines, along with the simple toolbar, minimised panels and the default hand-drawn rough style for shape outlines, shading, connectors, and text labels feels like an informal physical whiteboard, much less intimidating than traditional diagramming apps.

Plan, design and track projects with diagrams in remote teams

Teams in different departments use many different methods to plan projects, but most of these plans are initially sketched on a whiteboard. Collaborate in real time and online with distributed team members, customers and stakeholders easily in the diagrams.net whiteboard-like editor theme throughout your project development process.

Draw dependency graphs in diagrams.net

As a type of directed graph, dependency graphs visualise processes or situations where there are dependent components such as in decision making, scheduling, product development, IT or telecommunications infrastructure, supply and manufacturing chains, and more. They help you find the optimal order and identify critical paths or weak links that would constain your application, infrastructure or process.

BPMN 2.0 shapes for detailed process flows and choreography models

Business Process Model and Notation (BPMN) is a standardised diagramming system used to visualise business processes. BPMN diagrams are a form of flowchart, similar to UML activity diagrams. While it is typically used by business analysts and managers, its simple and understandable set of shapes and flows makes it a good choice to document processes for stakeholders in any department.

Use swimlanes with flowcharts to show who does each step

Flowcharts are one of the most common diagram types, showing all of the steps that must be followed to complete a process. Not many processes are limited to just one person or one team, which is why swimlane diagrams and cross-functional flowcharts are used - these show the flow of data or control across different groups.

use cases

Story mapping

User story diagrams are quite strongly related to UML use case diagrams, and both are used in an agile software development context. Both types of diagrams are used to explore and document customer requirements, they identify different groups of users and their goals, but they are used in different ways.

UML 2.5 shape library with updated shapes

The Unified Modeling Language (UML) is a set of standard symbols and diagram types, commonly used in data modelling, workflow visualisation, and system modelling. UML notation is the defacto industry standard in the fields of software development, IT infrastructure, business systems and other fields. Many languages, such as SysML, SoaML, and a number of architecture frameworks use and extend UML.

Create diagrams directly in VS Code

Diagrams make coding go a lot smoother, especially when you are programming in teams. Having diagrams version tracked and right with the code they reference, and version tracked similarly in your code editor saves you time. You don’t have to exit your workspace to switch to an external tool, or have to export/import every time you want to update a diagram.

How to create a gitflow diagram

It’s easier to show new development team members your project’s branch structure in your Git repository visually than to describe it in words. Some platforms may illustrate this using built-in tools. If you are using a platform without a convenient visual representation, it’s easy to create your own gitflow diagram.
