Predictika · Combine harvester quotes

An AI sales agent's combine harvester quote, checked before it goes out

An AI sales agent prepares a quote for one or more CLAAS LEXION combine harvesters: the model, a CONVIO FLEX header, wheels or TERRA TRAC tracks, options such as the extended grain tank and CEMOS AUTOMATIC, the MONTANA hillside variant and a discount. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of how the machines and options fit together and returns a verdict, every reason and the figures it computed.

Scope: CLAAS LEXION combines (8900, 8800, 8700, 8600, 7700, 5500): CONVIO FLEX header, TERRA TRAC tracks, extended grain tank, CEMOS AUTOMATIC, DYNAMIC COOLING, MONTANA, discount and fleet size. See everything this validator covers

This validator models a quote for the CLAAS LEXION combine harvester range, using CLAAS product names, not just the scenarios shown underneath.

  • Models and headers — six LEXION models and five CONVIO FLEX headers, with each model modeled to take only a range of header sizes.
  • Tracks and options — the LEXION 8900 on TERRA TRAC tracks only, tracks not offered on the 5500, the extended grain tank on the 8700, 8800 and 8900, CEMOS AUTOMATIC and DYNAMIC COOLING.
  • MONTANA hillside — offered on the 7700 and 5500, on wheels, with headers up to the F1230.
  • Discount, fleet and net price — a discount of up to 10 percent, the net price a quote states against the net price computed, and a fleet of three or more machines.
  • Approvals — a discount above 5 percent and a fleet order go to sales management.

Any LEXION combine quote that touches these rules is in scope — not only the scenarios pictured here. Not covered: tractors, forage harvesters, service and financing. The prices in this validator are illustrative values chosen for the demonstration, not CLAAS prices, and the page shows no price table. Which header fits which model, the tracks and tank availability, the MONTANA limits, the discount ladder and the fleet approval are modeled from comparable combine harvesters and are not published by CLAAS.

The AI sales agentBuilds the combine harvester quote from the conversation with the customer and says it is ready.

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
Headers that fit only some modelsOnly with care
Each model takes a range of header sizes, so a validation rule needs a lookup of the range per model and a comparison with the header on another line.		The model and the header are fields of one request and are compared with the modeled range on every call.
Options that exist only on some modelsOnly with care
Tracks, the extended tank, CEMOS AUTOMATIC and MONTANA are each limited to some models, so each is its own rule keyed to the model, and a new model means editing all of them.		Every option and the model are in one request and are checked together.
MONTANA rules that tie several choices togetherOnly with care
The hillside variant needs a 7700 or 5500, wheels and a narrow header, so three rules must be kept in step.		The variant, the model, the tracks and the header are checked together on every call.
A stated net price that must match the computed priceOnly with workarounds
The net price is the list price of every machine less the discount, so a separate rule is needed to recompute it and compare it with the stated figure.		The stated net price is a field of the request and is compared with the computed net price in the same pass.
Every problem returned in one answerOnly with workarounds
Rules tend to fire as the quote 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
Click to expand
    
Every rule is checked on every call, in any order the choices arrive; one problem never hides another. Blocking findings stop the quote; approval findings need a person to sign off; everything else is computed.

    
1The CONVIO FLEX header on the quote is not in the modeled options for this LEXION model.
2The LEXION 8,900 is quoted on TERRA TRAC tracks only; the quote has wheels.
3TERRA TRAC tracks are modeled as not offered on the LEXION 5,500.
4The extended grain tank is modeled as an option for the LEXION 8700, 8,800 and 8,900 only.
5CEMOS AUTOMATIC is modeled as not offered on the LEXION 5,500.
6The MONTANA hillside variant is offered on the LEXION 7,700 and 5,500 only.
7A MONTANA hillside machine takes a header up to the F1,230 only.
8A MONTANA hillside machine is modeled on wheels; the quote also has TERRA TRAC tracks.
9The quote states a net price of 841,660 USD, but the quoted machines come to 851,660 USD.
10A 8 percent discount is above the 5 percent a salesperson can give; sales management should approve it.
11The quote gives a 11 percent discount; the modeled limit is 10 percent.
12An order for 3 machines is a fleet order; sales management should confirm delivery slots and terms.

The text of the narrated walkthrough, step by step.

    
    
      
  1. Welcome to a demo of Predictika's Validator. An AI sales agent prepares a quote for one or more CLAAS LEXION combine harvesters: the model, a CONVIO FLEX header, wheels or TERRA TRAC tracks, and more. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of how the machines and options fit together 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 one LEXION 8700 with the CONVIO FLEX 1530 header, on wheels. The quote gives a 3 percent discount. The rest of the request is on screen.
    4. 
      
  4. Before it goes out, the agent calls the validator.
    5. 
      
  5. Blocked, with one finding, all in one answer. The CONVIO FLEX header on the quote is not in the modeled options for this LEXION model.
    6. 
      
  6. The validator returned one blocking finding 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 headers that fit only 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 header to CONVIO FLEX 1380.
    10. 
      
  10. It calls the validator again.
    11. 
      
  11. This time the validator clears it.
    12. 
      
  12. The earlier finding is cleared.
    13. 
      
  13. One problem 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.
