Answer: Has competitively valuable value chain match-ups with the company's present businesses such that its businesses can perform better together than apart.
Explanation:
The better-off test of diversification is that the company must gain a return that is higher than incremental growth. Incremental growth is usually defined a 1 + 1 = 2 formula and this test argues that Diversification must provide more than this such that the company achieves synergistic growth ( 1 + 1 = 3) which is what happens when different entities work better together than alone.
Diversification should therefore be into an area that will be able to match-up with the company's present businesses such that its businesses can perform better together than apart and produce even greater returns.
