• Processing and completion of survey may take more time than

expected

• Accessibility and clarity

– The possibilities to obtain the data – Use of graphs, illustrations, or metadata

compilation of statistics

different data sources to produce statistics

CBS Quality Challenges

• Quality has to be managed well with limited

budgets
