What is business concentration strategy?
Business concentration is much like a pond at your local park. There are hundreds of little fish. Some of these fish over time grow larger and as they grow larger they get hungrier. As this occurs the little fish who aren't as big and strong as the bigger fish begin to be consumed by the larger fish and die off. Then you have the other fish who like to group together for protection. Put this into a business perspective, there are 100's of small businesses as the year's progress, smaller business die off. Some of the smaller businesses decide to group together and the other businesses keep growing. Eventually you are left with one or two big businesses that has hasn't stopped growing and a few other smaller business that have merged. This situation is the nature of business not only here in Australia, but throughout the world.jordan...
