Cost Centres, Profit Centres, Investment Centres

The increasing complexity of today’s business environment makes it virtually impossible for most firms to be controlled centrally. Decentralisation is a necessary response to this increasing complexity and involves the delegation of decision-making responsibility by senior management to sub-ordinates. The structure is such that decision making is dispersed to various units within the organisation, with managers at various levels making key decisions relating to their centre of responsibility. These centres of organisational activity are known as responsibility centres and may be defined ‘as a unit of a firm where an individual manager is held responsible for the unit’s performance.’1

The performance of each centre and its manager is measured and controlled through a system of responsibility accounting which is based on the principles of locating responsibility and tracing costs/revenue/investments etc. to the individual managers who are primarily responsible. The division of the firm into separately identifiable units of responsibility allows for more accurate measurement of managerial performance because local information is more thorough. Overall, in order to obtain an accurate measurement of managerial performance, measures should be based on elements which the manager can control or significantly influence.

There are three main types of responsibility centre. A cost centre is the lowest level of responsibility, and performance is measured in terms of the costs incurred by it. Cost centres do not generate revenue and therefore have no profit objectives, which differentiates it from profit and investment centres. Managers of cost centres are accountable only for controllable costs and are not responsible for level of activity or long-term investment decisions. Managerial performance is measured by efficiency of operations in terms of the quantity of inputs used in producing a given output. The basis of this type of measurement lies in comparing
