Answer:
All the above options are correct.
Step-by-step explanation:
Value chain match-ups give rise to competitive advantage if it allows sister companies to leverage economies of scale by sharing production resources to the end that costs are significantly reduced, skills and technology are transferred and information grows within the system.
If any sub-business within a diversified group is taking more resources than it is contributing, it should be evaluated for possible course correction, "tune-ups" and or turn around interventions.
When there is a poor match between the parent company and the newly acquired company, there is often the need to re-evaluate the decision. If it is possible to effect a turnaround, at the least cost possible, the parent company would most likely do that otherwise, it "disconnects the umbilical cord".
Finance is a critical factor with maintaining a diverse array of businesses. Ideally, each business should be responsible for it's financial health. However the collective financial health of each sub-business is also reflective of the ability to monitor the progress of each subsidiary an make good business calls.
