There are large parts of this I really like, but it's hard to overstate just how much I disagree with the idea that "The only meaningful measure of productivity is impact to the business". The natural result of this view is a focus on quantifiable changes and short term thinking. The greatest value of experienced engineers is in avoiding landmines that will destroy a project or even a company. It's difficult to quantify things that never happen, or communicate the value in avoiding them in terms that don't sound wildly hyperbolic.
