Im unconvinced. Making sciency charts doesnt mean there's well grounded research.
The only place i worked that had a WIP limit... i never got the point. Like agile seems to be largely about visibility for management or clients, so the idea of artificially restricting people from reporting what theyre doing... like why?
By the way here's what actually happens when you set in place WIP limits. I think most of us adult professionals realize that a person has a few things on their plate and a thing can be "in progress", but waiting on something, and they probably don't have the patience to move it around on your JIRA board every couple hours. So your task management essentially becomes a narrative. So you get people to lie to you and pretend like they're super focused on this one priority. It's a ridiculous game. Just don't play it.
