Business Operations Survey: 2011

Revisions

Expenditure on research and development (R&D), and innovation can be difficult to collect. Businesses may have difficulty in interpreting the definitions of R&D and innovation, causing differences in their reported figures each year.

During the process of verifying the 2011 figures, some businesses were contacted to identify any reporting errors in previous years data. Therefore, some figures from previous years have been revised to make them comparable with 2011 data.
