Optimal Dairy Systems - key performance indicators
To help improve your competitiveness, we have created a clear set of measures and targets so you can benchmark your performance and identify areas for improvement.
The measures are broken down into two areas:
- Enterprise key performance indicators which highlight the six key areas for both all year round (AYR) and block calving systems which are crucial to delivering the financial performance required
- Three key business measures that every business should know, understand and benchmark their performance against.
The measures can be found in the tables below and show what excellent, good and average operators are currently achieving using Dairy industry data from the top 5%, 25% and average performers.
