Common questions
What does the centre count show?
It shows the items counted in design, research, engineering and delivery together.
Why use four sets?
Four sets are useful when each capability area and their overlaps are central to the discussion.
How can I keep it readable?
Use short labels, concise counts and a companion table for detailed assignments.
