There are a number of factors that have come from Campus Computer LTD growing in size.
As said in the case study they have benefitted from being capital intensive as the supply of there products and services can meet with the demand (an issue in previous pages). This is classed as a technical economy of scale, as a result of the technical economy of scale the company can invest in better more up to date equipment which will result in better quality products, leading to better customer satisfaction. As well as the ability to use lean production (the reduction of waste) because capital intensive production makes very little mistakes, this in turn will reducing costs and increasing profit.
As a business grows there is also more influence with both branding and there negotiation power (porters competitive forces). Because the business is larger and has more customers the branding of the business will then allow products to be priced higher (as long as quality is already established) this will obviously mean higher profit. Negotiation power of suppliers looks at how cheaply/ readily available Campus Computers LTD can obtain the computer parts as well as stock. As the business becomes larger the negotiation power will usually increase; this will result in lower costs, more selection of products and higher profit. It can also stimulate customer satisfaction because customers will have a larger selection of products (the business is more flexible).
However there are diseconomies of scale that can result in a business gaining disadvantages from growing.
As there organizational structure has a lot of layers communication can become a problem. With more layers information can be changed (by fault) which will result in mistakes being made further up the hierarchal structure, these mistakes could be very costly for the business especially if financial decisions are being made. Poor communication can also result in decisions and change taken longer than normal, this is because it will usually have to go up through the layers of the hierarchy, a flatter structure will eliminate this. As a result of poor communication more time will be needed, and time will equal money as the opportunity cost of a manager spending along time on a small decision is the fact that they could be making a more important decision that will make the business more revenue. More time will also be taken up from reviewing employees work and can also create a “them and us” culture within the business, which will alienate the employees and could create lower efficiency and poorer quality.
