Pneumatic is a modern forward-looking workflow management system that lets you build highly-customizable branching standard operating procedures and then run multiple workflows from each such SOP. Organize your tasks into sequences, and add data fields to ensure all the relevant information gets passed down the pipeline and nothing gets lost as the process is handed over from one team to the next. Do it in a highly effective graphical user interface. Run workflows, export key metrics into external applications via the public API, measure the performance of your workflows, and go back and refactor them on the fly, with Pneumatic dynamically propagating the changes you make to all the running instances of our SOP in the system. Engage with external users by allowing them to launch new workflows in Pneumatic via shared kick-off forms and by inviting them as guests to specific tasks. This feature offers an ideal solution for companies that hire a lot of contractors and freelancers – assign tasks to them via guest email links.
