Predictika · Precision fertiliser spreader orders

An AI sales agent's fertiliser spreader order, checked before it goes out

An AI sales agent prepares an order for a precision fertiliser spreader from a public product brochure, with a frame, hopper, drive, spreading vanes, part-width sections and options. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the brochure's published rules and returns a verdict, every reason and the figures it computed.

Scope: AMAZONE ZA-TS mounted and ZG-TS trailed fertiliser spreaders: model, frame, hopper, drive, vane sets, part-width sections and options. See everything this validator covers

This validator models orders for the AMAZONE ZA-TS (models 1400 to 5000) and ZG-TS (7501 and 10001) spreaders as described in the public brochure, not just the scenarios shown below.

  • Model, frame and hopper — the Super and Ultra frames offered for each ZA-TS model with their payloads, the S 600 and L 800 bolt-on hopper extensions, and the hopper capacity and payload of each model, compared with what the customer needs and what the order states.
  • Drive, sections and working width — Tronic, Hydro or Hybrid drive, the tractor oil flow each hydraulic drive needs, 8 manual or up to 16 (Tronic) and 128 (Hydro) part-width sections, and the 15 to 54 m working width ranges of the TS 10, TS 20 and TS 30 spreading vane sets.
  • Options and terminal — WindControl (not with Tronic), the hydraulic roll-over cover valve, Quick Hitch, the ZG-TS steering axle and EBS, ProfisPro on the ZG-TS, GPS ScenarioControl on the AmaTron 4, and other ISOBUS terminals sent to a person to confirm.

Any order for these spreaders that touches these rules is in scope — not only the scenarios pictured here. Not covered: prices (the brochure lists none, so this validator produces no price build-up or line-item quote), other AMAZONE spreader and sprayer lines, the ZG-TS Truck, and equipment the brochure shows without rules. Assumptions: the ZG-TS is treated as a hydraulic-drive machine for WindControl and section limits; the oil flows are the brochure's tractor requirements.

The AI sales agentBuilds the spreader order from the conversation and says it is ready.
Predictika validatorChecks every rule at once and returns the verdict, each finding, and the computed figures.

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
WindControl and 128 sections only with the Hydro driveOnly with care
Each option depends on the drive on another line, so every drive needs its own set of option rules that must be kept in step with the brochure.		The drive and every option are in one request and compared on every call.
Frames and hopper extensions that exist only for some modelsOnly with care
An availability table per model, usually a rule or a lookup for every model and every frame, maintained by hand.		The model sets which frame and extension are allowed and every choice is checked against it.
Tractor limits such as oil flow in litres a minute and valvesOnly with workarounds
The figures describe the customer's tractor, not a product line, so they need extra fields and rules that compare them with each drive's requirement.		The tractor figures travel with the order and are compared with the drive's requirement on every call.
A stated hopper capacity that disagrees with the configurationOnly with workarounds
The figure the agent states is free text or a separate field, so it takes an extra rule that compares it with the capacity the model, extension and frame actually give.		The stated figure is part of the request and is compared with the computed capacity 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.

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 precision fertiliser spreader from a public product brochure, with a frame, hopper, drive, spreading vanes, part-width sections and options. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the brochure's published rules and returns a verdict, every reason and the figures it computed.
    2. 
      
  2. I will start with the first request by the agent.
    3. 
      
  3. The agent says. Please quote a mounted ZA-TS 2600 fertiliser spreader with the Hydro drive, the Ultra frame, the Profis weighing system and the TS 20 spreading vane set for a working width of 30 m. The customer needs 3,400 litres of hopper capacity and a payload of 3,000 kg; the customer's tractor supplies 90 l/min of oil and has no double-acting valve. The rest of the request is on screen. The quote states a hopper capacity of 3,400 litres.
    4. 
      
  4. Before it goes out, the agent calls the validator.
    5. 
      
  5. Blocked, with five findings, all in one answer. The selected frame is not offered for this ZA-TS model; the brochure lists the Super frame for models 1400 to 3200 and the Ultra frame for models 2200, 2700, 3200, 4200 and 5000. No bolt-on hopper extension is listed for this model; the brochure lists S 600 for models 1400, 1700 and 2000 and L 800 for models 2200, 2700 and 3200. The customer needs 3,400 litres of hopper capacity; the quoted configuration gives 2,600 litres. The other two are on screen.
    6. 
      
  6. The validator returned five blocking findings 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 quote are checked against each other.
    7. 
      
  7. What this shows: for frames and hopper extensions that exist only for some models, 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 ZA-TS 2700 and the stated hopper capacity to 3,500 litres. It removes the hydraulic roll-over cover.
    10. 
      
  10. It calls the validator again.
    11. 
      
  11. This time the validator clears it.
    12. 
      
  12. All five earlier findings are cleared, and the validator's figure matches the quote.
    13. 
      
  13. Five problems caught in one call, fixed in one pass, and a clean quote. That is the value of Predictika's validator: catching mistakes before they reach the customer. Now you can try the other scenarios yourself.
    14.
