CBS is looking for a suitable model for quality management. One reason is that CBS wants to manage quality in a systematic way to meet the European Statistics Code of Practice and the Quality Declaration of the European Statistical System. Existing quality systems do not fully meet CBS requirements, so a model was developed that would comply. One of the requirements is that the new model should combine with the EFQM Excellence Model. The OQM model is composed of components of well-known quality management models. This model is applicable to all areas of quality assurance and all types of organizations. It is called an object-oriented model, because objects play a central role in it.
