Recently, McDonald’s announced that it would end up the cooperation with Heinz, which used to be its best partner in French fries’ ketchups. What led to such astonishing change between these two companies was all about competitions. H.J. Heinz Co. was acquired by Bershire Hathaway and Brazil-based 3G Capital. 3G Capital also owns the Burger King hamburger chain, reports the Pittsburgh Post-Gazette.

McDonald’s decision ended up the long-term relationship with Heinz, which also affect customers’ choices. As for Heinz, it definitely suffers greater loss, even outside the US. What we can learn from this is that whatever the size of a business, managers should always pay attention to their decisions, taking into account what effect will be bought to them after the decisions are carried out. Never blindly take on a new client or partner, who might severely cause the conflicts with the existing ones.
