Inorganic (external) Growth:
Where a business gets bigger by joining with or buying another business
Merger - an agreement between two companies to join together and operate as one larger business
Takeover - one business buys control of another business, this often happens through buying shares in another business. This can be "hostile", when the directions in a business don't want to sell, but shareholders do due to the high price offered
Economies of Scale:
As a business gets bigger, the cost per unit falls
Financial - lower interest rates offered by banks
Managerial - better, skilled, trained staff and managers
Technical - faster, more efficient machinery
Marketing - costs for advertising spread over more units/stores
Purchasing - buying in bulk
Diseconomies of Scale
As a business gets bigger, the cost per unit rises
Control - more staff, more departments
Co-ordination - more supervisors/team leaders needed
Communication - more staff, more layers, decisions take longer
Vertical Backward Integration - Join with or takeover a supplier (e.g. Tesco taking over a firm or ready-made meal producer)
Vertical Forward Integration - Join with or takeover a customer (e.g. Costco wholesalers taking over a chain of smaller shops to which they supply)
Horizontal Integration - Join with or takeover a competitor (e.g. Tesco taking over Sainsbury's)
Diversification - Join with or takeover a business in a new market (e.g. Tesco taking over a mobile phone network)
