This unit of competency covers developing an appropriate business case for proposed changes which will deliver improvements to the sustainability of a process or organisation. It includes benefit/cost and return on investment (ROI) analyses.This unit applies inside organisations and their value chains. The unit has been developed with manufacturing operations as a focus. However, because of the range of organisations in a typical manufacturing value chain it may also be applied to other types of organisations. The unit applies to the development of a business case for sustainability related improvements to an organisation’s products or processes. The business case may relate to the whole or part of an organisation, or to the whole or part of the value chain (e.g. suppliers of goods or services or customers). The business case may be required for sustainability related improvements in response to regulatory, Board, employee, shareholder or community requests or pressure.A manager or technical specialist who has a major responsibility for sustainability as part of a broader work role would typically undertake this, or sustainability may be their primary work responsibility. The manager or technical specialist may undertake this alone or as part of a team.The technical measurement of operational performance or measurement of emissions or other environmental impact is not covered by this unit. However, there is a requirement to present and organise data. The complexity of this requirement will vary according to the type and scale of the organisation’s processes.No licensing, legislative or certification requirements apply to this unit at the time of publication.
