Ask HN: Do you know a framework to build a systemic approach of your startup?

Computers, Earth, bands, aquariums, and startups are systems. Like me, you might have also felt the need to visualize the global picture of the business somewhere else than in our head, a business plan, or in a business model canvas. I find out that the systemic approach can help with that. I might be wrong but I believe that this system overview might be relevant to prevent failure, enhance synergies, and help to lower the carbon impact of a company.

Graphs with nodes, interconnected by relations similar to a mindmap are well known to represent systems. This graphic representation is powerful as a communication medium and like I said could be useful to analyze your business and stay ahead.

I know tools to build mindmaps but no one is focused on business and startup specificities. Do you know a startup-focused framework to build such systems?
