An AI sales agent's F-MAX tractor quote, checked before it goes out

An AI sales agent prepares a quote for a Ford Trucks F-MAX tractor unit: the variant, the 5th wheel height, final drive ratio and tyres, the options, and the wheelbase, length and gross vehicle mass the quote states. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the technical leaflets Ford Trucks publishes and returns a verdict, every reason and the figures it computed.

Scope: Ford Trucks F-MAX, F-MAX L and F-MAX LL 4x2 tractors (Euro 6E, March 2024 leaflets): 5th wheel, final drive ratio and tyre combinations, option availability and dependencies, and the stated wheelbase, length and gross vehicle mass. No prices. See everything this validator covers

This validator models the three F-MAX 4x2 tractor variants described in the public Ford Trucks technical leaflets, not just the scenarios shown below.

  • 5th wheel, final drive ratio and rear tyre — each variant's leaflet lists the combinations that go together (for example 1150 mm only with the 2.64 ratio on the F-MAX); a combination that is not listed is blocked.
  • Front tyres and steering — the 385/55, 385/65 and 355/50 front tyres are offered only with EHPAS steering and only with the rear tyre the leaflet pairs them with.
  • Options and their conditions — the parking cooler is not available with 315/80 tyres, the wet type cab heater requires the park heater to be deleted, the no-lube 5th wheel plate is listed with a 1100 mm 5th wheel, and some options are listed for one variant only (for example the Lightweight Package for the F-MAX, fuel tank options by variant).
  • Stated figures — wheelbase, overall length and technically permissible gross vehicle mass (19000 kg with the F-MAX 7.5 T front axle option) are compared with the quote, and a combination weight above the 44000 kg GTM is blocked.
  • Market-dependent equipment — the leaflet says the DAB radio is standard or optional according to the market, so a quote with it needs a person to confirm.

Any F-MAX tractor quote that touches these rules is in scope — not only the scenarios pictured here. Not covered: prices (none are in the leaflets), the Cargo and other Ford Trucks ranges, other axle configurations, body and trailer compatibility, and options not named above. The leaflets state that they are not an assurance of specifications, so the model reflects the leaflets read in October 2026.

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
A 5th wheel, ratio and tyre combination the leaflet does not listOnly with care
A per-variant compatibility table that must be written and kept up to date for each variant.		The variant, 5th wheel height, ratio and tyre are in one request and checked together on every call.
An option that depends on another (EHPAS, deleted park heater, tyre size)Only with care
Each dependency is its own product rule, and rules for three variants multiply.		Dependencies are checked on every call, in any order the choices arrive.
A stated gross vehicle mass that disagrees with the optionsOnly with workarounds
The 19000 kg figure depends on a variant and an option; checking a stated figure against it takes extra rules and formulas.		The stated figure is a field in the request and is compared with the computed one.
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.

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.

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 a Ford Trucks F-MAX tractor unit: the variant, the 5th wheel height, final drive ratio and tyres, and more. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the technical leaflets Ford Trucks publishes 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 Ford Trucks F-MAX LL 4x2 tractor with a 980 mm 5th wheel, a 2.31 final drive ratio and 295/60 R22.5 rear tyres. The quote states a wheelbase of 3600 mm, an overall length of 5925 mm and a gross vehicle mass of 18,000 kg. The rest of the request is on screen.
    4. 
      
  4. Before it goes out, the agent calls the validator.
    5. 
      
  5. Blocked, with five findings, all in one answer. The 385/55, 385/65 and 355/50 front tyres are available only with the Electro-Hydraulic Power-Assisted Steering System (EHPAS), which is not on the quote. The front tyre option is not listed with the rear tyre on the quote for this variant. The wet type cab heater requires the park heater to be deleted (Less Park Heater), and the quote keeps it. 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 an option that depends on another (EHPAS, deleted park heater, tyre size), a rules-based CPQ is error-prone for this.
    8. 
      
  8. Now the agent resubmits.
    9. 
      
  9. The corrected request. It changes the variant to Ford Trucks F-MAX, the 5th wheel height to 1,100 mm, the final drive ratio to 2.47 and the rear tyre to 315/70 R22.5. It sets the EHPAS steering to yes.
    10. 
      
  10. It calls the validator again.
    11. 
      
  11. Still blocked, with two findings, all in one answer. The wet type cab heater requires the park heater to be deleted (Less Park Heater), and the quote keeps it. The quote states a technically permissible gross vehicle mass of 18,000 kg, but the quoted configuration gives 19,000 kg.
    12. 
      
  12. Four findings cleared; still blocked on wet type cab heater without deleting the park heater, and newly found: stated gross vehicle mass differs.
    13. 
      
  13. The agent resubmits once more.
    14. 
      
  14. The revised request. It changes the stated gross vehicle mass as to 19,000 kg. It sets the park heater deleted to yes.
    15. 
      
  15. It calls the validator once more.
    16. 
      
  16. This time the validator clears it.
    17. 
      
  17. Both earlier findings are cleared.
    18. 
      
  18. Five problems caught in one call, fixed in two passes, and a clean quote. That is the value of Predictika's validator: catching mistakes before they reach the customer.
    19.
