BPMN Shapes - Black pool

Hi @mymy 

This is a great idea that Lucid could use to make improvements for all shapes in the future

Adding short, helpful hints that pop up when you hover over each element would make the user experience much better - especially for those who aren't familiar with the symbols used in business process mapping.

Would you prefer adding your idea in the below navigation to get this registered in your name.

sorry I don’t have time, I just need that shape explanation, can you share with me?

as a non english speaker that flies above my head. Do they mean black pool are for external participants to a company like suppliers?

Hi @mymy, that’s correct - black pools are to represent external participants whose processes you don’t need to display or know in detail. A supplier could be a good example of this. However, an external participant doesn’t have to have a black pool. Displaying process details within a pool might still be useful for an external participant if you want or need to have insight into them or they’re relevant to the other internal processes in your diagram. 

To summarize, a black pool is a pool where the contents is either unknown to you or out of your control, or irrelevant. Use it in a diagram when you want to refer to an external participant whose processes are out of your control or irrelevant to the diagram you are making.
