Ms Laura Burke:

We literally do that on an annual basis in the context of workforce planning. We use a different model to govern the money we spend on external resources in different areas of the organisation. I am certainly satisfied that this model is fit for purpose and we are satisfied with it. There are areas where outsourcing is suitable. Again I would cite the national waste prevention programme as an example. There are other areas where we will not outsource, such as our core licensing function or our inspection and enforcement functions regarding industrial facilities. We look at that on a regular basis.
