I agree except that since it's apparently been going on for a while, there's no time now to allow him to "repeatedly" fail. Ideally, this improvement plan would have already been attempted and the results of that (assuming there were repeated failures) could be included in the info provided to the Board.

At this point, he should just go directly to the Board and include his proposed improvement plan in his presentation. The co-founder has already indicated an unwillingness to change or leave; the Board should be able to force it.
