@Rony_Sklar Yes. There are several options out there (and almost all can be investigated and compared here on IT Central Station, in fact :)). If one only wants to do the diagrams, and not interested in using the diagram output as input to one of the other tools (Bizagi, Appian, Pega, Alfresco, et al.), then even Visio works well to do the diagramming. One could even do it in a paint or presentation application.
@Mark McGregor helpful advice. Thanks for weighing in :) I agree that it's important to define what your purpose is before investing in a tool - do you have some advice on how to choose BMPN tools once one has defined a clear purpose? What questions should one ask about the tool whilst comparing the options?
What is the difference between ERP and BPMS Tools? On which elements can we rely to decide if we used an ERP (Like Odoo) or a BPMS tool (e.g. Camunda, BONITA) to develop an application?
Thank you for your response.
