This unit describes the skills and knowledge to optimise the sustainability performance of a complete work area in a plant or part of the manufacturing value chain. It includes ensuring that production systems comply with sustainability and environmental requirements and that optimal process, plant and equipment utilisation is planned and carried out. It also covers problem solving to fully meet sustainability needs and to ensure that production of finished goods meets customer requirements. The unit applies to products made, services offered, and use of sites by an organisation or manufacturing value chain member (supplier of goods or services or a customer). This unit applies inside organisations and their value chains and has been developed with manufacturing operations as a focus, especially work areas that process materials or components to manufacture products. This unit applies to senior operators, technicians, team leaders or frontline managers and other support staff who optimise process systems as part of their work function. The unit includes all items of equipment and unit operations which form part of the process of a complete area and assumes that the required production, technical, science or other operational skills and knowledge necessary to work in the process or work area have already been gained. No licensing or certification requirements exist at the time of publication. Relevant legislation, industry standards and codes of practice within Australia must be applied.
