Predictika · Center pivot irrigation orders

An AI sales agent's center pivot order, checked before it goes out

An AI sales agent prepares an order for a Lindsay Zimmatic center pivot: the 9500P, 8500P or 7500P model, the tower clearance, control panel, tires, number and length of spans, overhang, variable rate irrigation, GPS end gun, soft barrier, FieldNET, discount and the order total. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of how those choices fit together and returns a verdict, every reason and the total it computed.

Scope: One Zimmatic center pivot order (9500P, 8500P or 7500P): clearance, control panel, tires, spans, overhang, options, discount and the stated total. See everything this validator covers

This validator models Zimmatic center pivot orders, not just the scenarios shown below.

  • Models and clearance — the 9500P, 8500P and 7500P, each offered with its own set of tower clearances, with ultra-high clearance needing a dealer check.
  • Spans, overhang and reach — the span length each model allows, the overhang limit, and the total reach of the machine, with a long reach needing a water-supply check.
  • Control panel and options — the 500C, 700C and 712C panels, with variable rate irrigation and the GPS end gun needing a panel that has GPS positioning and the 500C taking hard barriers only.
  • Tires — standard, wide and radial tires, with radial tires not offered on the 7500P.
  • Discount — a discount of up to 20 percent of the subtotal.
  • Stated total — the order total the quote states against the total computed from the modeled prices.

Any Zimmatic center pivot order that touches these rules is in scope — not only the scenarios pictured here. Not covered: linear move machines, other Lindsay products and field layout. Lindsay publishes no compatibility rules or price list for these choices, so every limit, rule and price here is modeled and illustrative. Amounts are in cents, as the validator computes them.

Where rules-based CPQ gets it wrong
Click to expand
    
Our assessment of what a typical rules-based CPQ (product rules, price rules and validation rules, as in Salesforce CPQ) does with the same cases. It is a judgment about effort and reliability, not a claim that nothing can be built.

    
What the validator caughtTypical rules-based CPQPredictika
Clearance sets that differ by modelOnly with care
Each model is offered with its own set of tower clearances, so every clearance needs a rule that reads the model, and the list grows with every model added.		The model and the clearance are in one request and are checked against each other on every call.
Options that depend on the control panelOnly with care
Variable rate irrigation and the GPS end gun need GPS positioning and the 500C takes hard barriers only, so each option is its own rule that reads the panel.		The panel and every option are fields of the same request and the dependencies are checked together on every call.
Span, overhang and reach limits that depend on the modelOnly with care
The span length, the overhang and the total reach are limited differently for each model, and the reach is computed from the spans and the overhang.		The reach is computed in the same pass and checked against the limits of the model on every call.
A discount capped at a share of the subtotalOnly with workarounds
The cap depends on a subtotal that is itself built from the model, spans, panel and options, so the subtotal has to be recomputed before the discount can be compared.		The subtotal is computed in the same pass and the discount is compared with it on every call.
A stated total that must match the computed totalOnly with workarounds
The total is built from the model, spans, panel, clearance, tires and options, so a separate rule is needed to recompute it and compare it with the stated figure.		The stated total is a field of the request and is compared with the computed total on every call.
Every problem returned in one answerOnly with workarounds
Rules tend to fire as the order is saved or a step is completed, so a rep often fixes one error and meets the next.		All findings come back together, whatever order the choices arrived in.

  

  

    
What this validator catches: findings from its test cases

Every rule is checked on every call, in any order the choices arrive; one problem never hides another. Blocking findings stop the order; approval findings need a person to sign off; everything else is computed.

    
1The 7500P is listed with standard clearance only.
2The 8500P is listed with Low, Standard, Medium and High clearance; ultra-high clearance is a 9500P option.
3Ultra-high clearance towers need a field and crop-height check by the dealer before the order is released.
4The 9500P is quoted here with Standard, High or UltraHigh clearance; Low and Medium are 8500P options.
5The span length is 211 ft; this model is modeled for 100 to 210 ft.
6The machine reaches 2,640 ft; a dealer should confirm the water supply and pressure before the order is released.
7The machine reaches 2,641 ft; this model is modeled for a maximum of 2,640 ft.
8The overhang is 121 ft; this model is modeled for a maximum of 120 ft.
9Variable rate irrigation needs GPS positioning, which the 500C panel does not have; choose the 700C or 712C.
10GPS end gun control needs GPS positioning; the 500C panel does not have it.
11The 500C panel is compatible with hard barriers only.
12Radial tires are not modeled for the 7500P.
13The quote states a total of 10,175,000 cents; the illustrative prices give 10,275,000 cents.
14The discount is above 10 percent of the subtotal; a sales manager should approve it.
15The discount of 2,055,100 cents is above 20 percent of the 10,275,000 cent subtotal.

The text of the narrated walkthrough, step by step.

    
    
      
  1. Welcome to a demo of Predictika's Validator. An AI sales agent prepares an order for a Lindsay Zimmatic center pivot: the 9500P, 8500P or 7500P model, the tower clearance, and more. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of how those choices fit together and returns a verdict, every reason and the total it computed.
    2. 
      
  2. I will start with the first request by the agent.
    3. 
      
  3. The agent says. Please quote one Zimmatic 8500P center pivot with ultra-high clearance, the 500C control panel and standard tires: 8 spans of 160 feet with a 40 foot overhang. It is ready to send. The rest of the request is on screen.
    4. 
      
  4. Before it goes out, the agent calls the validator.
    5. 
      
  5. Blocked, with three findings and one approval, all in one answer. The 8500P is listed with Low, Standard, Medium and High clearance; ultra-high clearance is a 9500P option. Variable rate irrigation needs GPS positioning, which the 500C panel does not have; choose the 700C or 712C. The 500C panel is compatible with hard barriers only.
    6. 
      
  6. The validator returned three blocking findings and one approval in one answer. A check that reads one field at a time would pass most of this; it shows only when the choices in the order are checked against each other.
    7. 
      
  7. What this shows: for clearance sets that differ by model, a rules-based CPQ is error-prone for this.
    8. 
      
  8. Now the agent resubmits.
    9. 
      
  9. The corrected request. It changes the model to Zimmatic 9500P, the tower clearance to high and the control panel to 700C. It sets the order total stated on the quote to 15,400,000 cents.
    10. 
      
  10. It calls the validator again.
    11. 
      
  11. This time the validator clears it.
    12. 
      
  12. All four earlier findings are cleared.
    13. 
      
  13. Four problems caught in one call, fixed in one pass, and a clean order. That is the value of Predictika's validator: catching mistakes before they reach the customer. Now you can try the other scenarios yourself.
