The Tech Stack Canvas

What are the advantages of using a canvas instead of a document template?

IMO the main advantage is using it in facilitation workshops, whether in a remote setting using tools like Miro, or in-person meetings using printed sheets of paper with the canvas.

While there are other visualization, diagramming, and mapping methods which adding real value, the canvas, IMO, just rearranging a template to fit on a landscape-oriented sheet of paper ;)
