A team reports that it delivered forty-two items last quarter, up from thirty-one. The product owner is asked whether the product improved. What is the accurate way to describe the relationship between these numbers and the answer?

• AForty-two items is output. Whether anything improved depends on what changed for users and for the organisation, and output and outcome are not proportional.
• BMore items delivered means more value, so the product improved.
• CThe comparison is invalid because item sizes differ between quarters.
• DThe product improved if the items met the Definition of Done.
