Often organizations use their own tool, such as Microsoft Visio, to draw flows. The same applies for marketing automation campaign logic. I found out that marketers draw their own logic in a different way than one would do in the Sitecore Marketing Automation tool.
So why not create a Microsoft Visio stencil with all the Sitecore Marketing Automation elements? That way your marketers can draw flow logic the Sitecore way which makes it easy to re-create inside Sitecore. No more translations from one logic to another.
