Scarlatti is working with DairyNZ to develop a scorecard that measures the competency of farm teams to enable tracking of an industry target: that 90% of dairy farms have fully competent teams by 2020. This required developing a definition for competency, which we defined as a function of qualification, experience and innate ability. A simulation-based approach using Scarlatti’s Inchworm tool was used to understand the relative importance of each factor and link different industry interventions with measurable outputs. The outcome of the simulation was then evaluated against the industry target by collectively assessing the workers’ competency.
