Business Process Model and Notation (BPMN), a kind of flowchart language, helps demonstrate what actions need to be taken, the sequence they need to be carried out in, and who should execute them. You can add extra data elements to its basic structure to explain more about how a process interacts with information, aiding the design of information technologies like SmartSuite.
However, as revealed by astute questions by Vasken Bakalian and Bud Ward, BPMN's capacity to detail data management architecture is limited. This is an intentional part of its design. While BPMN is extremely useful for no-code developers, sometimes it's beneficial to use other tools in combination with it. Simply put, you could use pliers to drive a screw, but it's not the best tool for the job.
