    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.

    Create a mindmap from text with PlantUML

    Mindmaps are useful to quickly capture ideas, and are easy to draw in diagrams.net and our draw.io branded apps. But some people prefer to work from text lists when brainstorming. Drop a text list into the PlantUML import tool and diagrams.net will generate your mindmap for you - no need to fuss with connectors or layouts.

    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.
    diagrams.net contains several examples of UML sequence diagrams in its template library

    Create UML class diagrams

    UML class diagrams are used to illustrate the structure of a computer program. They detail the types of data or attributes stored within each ‘class’, the methods (operations or functions) that each class provides, and the relationships between the classes.

    Draw circular flowcharts

    Flowcharts are one of the most used types of diagrams in all teams. But some process flows are circular or cyclical rather than a series of steps with a start and end. You can create circular flowcharts in diagrams.net and our draw.io branded apps in a number of ways.

    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.

    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.

    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.

    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.

    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.

    Use org charts to categorise data and show hierarchies

    Org charts, also known as tree diagrams, organisational charts, and organigrams, are used throughout all disciplines and professions. We like to categorise everything as it helps us make sense of how the world works. Species of plants and animals, corporate and military hierarchies, team structures, family trees, language family relationships, even symptoms of illnesses - org charts help us quickly find who to contact, what illness to treat, and so on.

    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.

    Analysing vulnerabilities with threat modelling using diagrams.net

    Threat modelling, especially in IT, is becoming more common. Companies are increasingly aware of the risks of having their infrastructure and devices connected to the internet. As more devices, machines, sensors, monitors, and applications are added to a company’s infrastructure, there are potentially many more vulnerabilities.
