How do analytics support decision making?
What should I do Now??? DO
THIS!
Analytics helps people (or systems!) Do the Right Thing -- ACTION
Analytics guides strategy and policy making -- INSIGHT
We should do this!

User Experience Problem – How do you know what to do?
Initial Assays (Mill Feed)
Attributes of the most experienced Operator:• Monitors the initial feed • Makes changes early to impact downstream• Intuitively knows the relationship between
the numbers because they’ve seen it many times

The Data: A Lot of It
14
Where does the data come from?
What does it mean?
![Page 15: Rob Risany Aviana Global](https://reader036.vdocuments.us/reader036/viewer/2022062422/5681369b550346895d9e37bd/html5/thumbnails/15.jpg)

The mill process is highly time lagged
Data about the “current process” is actually reflecting different ore at each stage of a 45 minute process
Data Problem #1
![Page 16: Rob Risany Aviana Global](https://reader036.vdocuments.us/reader036/viewer/2022062422/5681369b550346895d9e37bd/html5/thumbnails/16.jpg)

Like the static on the radio, data noise is the stuff that interferes with the signal.
Another Problem– Data Noise Is Always There
Xray Sensors are very tempermental
We have to design an approach that can handle the noise
Rocks are not well organized

Applying a Business Concept to the Logic of how a system would work: Drive between the lines
BEFORENo guidance
AFTERWith guidance
Operators use their instinct to do as well as they can…
Analytics tells the operator what the lines are.
With better insight the operator can do a better job

Why not just get rid of the operator?
![Page 20: Rob Risany Aviana Global](https://reader036.vdocuments.us/reader036/viewer/2022062422/5681369b550346895d9e37bd/html5/thumbnails/20.jpg)

• Account for the data challenges• Create rolling averages in the data• Segment (group) mill feed into ore types
• Generate recipes for good & poor recovery• Generate rules for Lower half (poor recovery)• Generate rules of upper half (good recovery)
• Give the good recipes as guidance to the mill operators!• Track ongoing change
The concept of the system

It starts with the business context: Understand the current process
Understand the limitations of the current approach Bad Data Will Always Be With You. Plan for it! Design a practical system, not a perfect one It ends with business context: What is the return?
