RQ4. 1 Identify the major purposes of product costing. For each purpose discuss whether information about current or future product costs is required. What implication does your answer have for developing a product costing system?

RQ4.3 How common are product costing systems in practice? Why might a business choose to do without a product costing system?
L-S, T & H, page 134.
A recent survey of members of the Chartered Institute of Management Accountants (CIMA) found that less than 50 per cent of respondents had systems for costing products in their organisation, and in small organisations this figure fell to 34 per cent (CIMA, 2009).
The range of costs included within a product costing system varies from one organisation to another. A comprehensive picture of product costs requires the inclusion of upstream and downstream costs.
