Successful Delivery Index

Successful Delivery Index
What does it measure?• Two important aspects of supply are:
● Accuracy● managing what you measure
● Reliability● Changes to bay irrigation times● Changes to infiltration rates● Lead to on-farm inefficiencies or excess run-off or both
• The SDI provides a measure of supply reliability
13
Successful Delivery Index
What is it?
Success or fail on the basis of whether the delivered flow was within ±10% of the ordered flow or
±0.5 ML/day (whichever is greater) for 95% of the order duration

Root Cause Analysis

Conclusion• Customer and staff acceptance along with grasping the
potential of the system has been very positive after some shaky beginnings!
• The benefits to production, the water savings, lifestyle, occupational health and safety - are real
• Modernisation produces a data rich environment highlighting the problems within the channel system
• Modernisation projects inherit the problems of the past• Modernisation projects are about change, the construction
is easy, the real challenge is managing the change resulting on both sides of the meter
