An organisation that puts quality first grows a culture whose behaviour, attitudes, activities and processes create value by satisfying what customers and other relevant parties need and expect. How good its products and services are depends on how far they satisfy customers and on the effects, intended or not, that they have on relevant parties; quality is a matter not just of what a product or service is meant to do and how well it performs, but also of the value and benefit the customer sees in it.
