my 2 cent on that is that really depend of the industry and the ressources the company have. Like Dr. Kummer said i don’t think its a good idea to buy your customer or supplier. I think its better to focus on your core business and let people who are good at something do that. Imagine Walmart growing vegetable or making toys…. Like Polycom did in the past buy an enterprise who can feel a hole in the product it’s a good strategy. The only reason to go vertical is for a strategic move like sécurisation of a special ressources or a special technology. All major player outsource a lot these days.
