I think different organizations have different approaches to this. We did an audit not long ago on Statistics Canada and identified they have an appropriate system of quality assurance to make sure the data they are collecting is being properly stored. Of course, Statistics Canada's business is data. That is their core business, and we did find they had an appropriate system of quality control around the data they collect. I think that would probably be the first place to look.
