Every facility's main objective must be to ensure that manufactured medicinal products will be fit for their intended use, will comply with the requirements of the marketing authorization and will not place patients at risk because of inadequate safety, quality or efficacy. Having a proper facility design will facilitate obtaining appropriate quality products and will allow work to be done in an easier and proper manner in accordance with the existing machines, products, materials, flows and company policies. To undertake the design of a new or renovated plant, facility or system, the starting point is to detail the requirements with which to comply.
