I like this and it got me thinking about the part where the author talks about the the huge _space_ of work that we _start_ with and by the _time_ we're _done_ someone had done all the work in that space.
For me this is a good way of thinking when talking about performance and these shapes sure do make much more sense than a bunch of Dnd stats. But taking time into consideration and how things always change it's easy to see how software development isn't always about convergence and subtraction. You may have roles that when they are underperfoming they add work, needless work, to the project. I'm of course talking about the grand architects. The ones that during the project decide, "this isn't working we need to make our solution less coupled and this is my new kinda micro service oriented way of doing things" which totally changes the work space and might introduce subtle holes that no current shape in the project covers even though they all covered the previous work space.
But if the grand architect is right, the change could shrink the work space and convergence sped up but then some shapes might be redundant which is another challenge.
