Open source diagramming application for teams that lets users keep their diagram files in storage they choose
Explaining something abstract is easier with a drawing than with paragraphs of text, and that is the thinking behind ProcessOn, an online collaborative diagramming platform. Its makers say diagrams help people understand and remember things that are abstract and obscure.
ProcessOn supports flowcharts, mockups, BPMN, UML and mind maps. Flowcharts and BPMN show how a process runs, UML is the diagram family used in software design, mockups sketch screens, and mind maps organize ideas.
Because the platform is online and collaborative, several people can build diagrams together. The vendor suggests using a diagram rather than lots of words when explaining something complicated to others, which is the practical use for a team that needs to share a process or a plan with colleagues.
ProcessOn is a web-based platform where people draw diagrams together. It supports several diagram types, and its makers argue that a picture explains complicated or abstract ideas more clearly than a long text.
Because it runs online, colleagues can work on the same diagram without exchanging files.
Anyone who needs to explain a process or idea visually. The sources do not name specific industries or customers.
