A process is a set of activities which produces an output -product or service- valuable for the customer. Ensuring quality of products and services requires high amounts of cooperation between the different actors in an organization. This suggests the use of workflow techniques in order to implement quality. Workflow management systems allow the control of flow of work and guarantee that a job shall execute in accordance with a predefined structure. We show how workflow management systems can be instrumental in satisfying quality requirements which are defined in the ISO 9000 standard. Also, the manner in which workflow facilitates the satisfaction of the five essential principles of TQM is shown.
