Capacity shortage - a firms capacity is not large enough to deal with the level of demand for its products

  • unsuccessful marketing 
  • seasonal demand 
  • over investment in fixed asset 
  • a merger ot take over leading to duplication of many resources and sites

Capacity Utilisation

Advantages of Spare capacity

  • there is more time for maintenance and repair of machinery, for training and for improving existing system 
  • less pressure and stress for employees who may become over worked at full capacity 
  • under utilisation allows a company to cope with sudden increase in demand

Disadvantages of Spare capacity 

  • firms have a higher proportion of fixed costs per unit 
  • higher unit costs will lead to either lower profit levels or the need to increase price to maintain the same profit levels 
  • spare capacity can portray a negative image of a firm, suggesting that it is unsuccessful 
  • with less work to do, employees become bored, demoralised lowering their motivation and efficiency

Subcontracting

when a organisation ask another business to make all part of its product

Advantages

  • businesses will be able to react to changes in demand more quickly 
  • subcontractors may be more specialised and therefore more efficient in a particular line of activity 
  • lets a firm focus on its core business and helps it to avoid becoming involved in activities in which less competent 
  • non-standard order can be given to a subcontractor so that the business benefits from the order but suffers no disruptions to its normal production 

Disadvantages

  • must recognise that the quality of their service is no longer directly under their own control 
  • excessive subcontracting erodes a companies operations base and its ability to initiate research and make changes 
  • opportunity cost of subcontracting should be evaluated 
  • may require a firm to give confidential information to a suppler, e.g details of its method and patents
