An AI sales agent's motorcoach configuration, checked before it goes out

An AI sales agent prepares a configuration for a J4500 or J3500 touring coach: the engine, the number of passenger seats, passive rear steering, and the axle, horsepower and alternator figures it orders. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the published MCI J-Series brochure and returns a verdict, every reason and the listed values it compared against.

Scope: MCI J4500 and J3500 coaches: engine for the model, seating capacity, passive rear steering, and stated horsepower, axle ratings and alternators. See everything this validator covers

This validator models availability and figures printed in the MCI J-Series brochure (updated May 2025) and the MCI J-Series specs page, not just the scenarios shown below.

  • Engine — the Cummins X12 (410 hp standard, 455 hp optional) is listed for the J4500 and the Cummins L9 (350 hp) for the J3500; an engine from the other model is blocked.
  • Seating — up to 60 passengers on the J4500 and up to 44 on the J3500.
  • Rear steering — the passive rear steering system is listed for the J4500 and is not listed for the J3500.
  • Stated figures — the horsepower, the front axle rating (J4500 17,000 lb; J3500 14,500 lb), the drive axle rating (J4500 23,000 lb; J3500 27,500 lb), the tag axle rating (J4500 16,500 lb; none listed for the J3500) and the alternators (J4500 two 250 A; J3500 two 180 A) are compared with what the order states.

Any configuration of these two coaches that touches these rules is in scope — not only the scenarios pictured here. Not covered: prices (MCI publishes no price list for its coaches, so there is no price build-up or line items); the J4500 CHARGE and the other MCI coaches; the Base, Preferred and High specification columns, which the brochure describes as typically included or not and not as rules; options that are listed the same way for both models (for example the 360-degree camera, seat styles, lighting, audio and the application groups); and the turning-radius figures, which the public specs table does not align reliably. The brochure says specifications are subject to change without notice.

The AI sales agentBuilds the coach configuration from the conversation 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
Engine and axle choices that exist for one model onlyOnly with care
The J4500 and J3500 share a platform but have different engines, axle ratings, alternators and rear steering, so each choice needs a rule against the model, and a pick-list copied from the other model has to be caught.		The model decides which engine and ratings are listed, and every choice is checked against it on every call.
A stated rating checked against the listed oneOnly with workarounds
The agent states a horsepower and axle and alternator figures, and each has to be compared with a value that depends on the model and engine; a mismatch has to stop the order.		The stated figures are fields in the order, and the validator blocks when one differs from the brochure.
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.

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.

The text of the narrated walkthrough, step by step.

    
    
      
  1. Welcome to a demo of Predictika's Validator. An AI sales agent prepares a configuration for a J4500 or J3500 touring coach: the engine, the number of passenger seats, passive rear steering, and more. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the published MCI J-Series brochure and returns a verdict, every reason and the listed values it compared against.
    2. 
      
  2. I will start with the first request by the agent.
    3. 
      
  3. The agent says. Please configure a J3500 coach with the Cummins L9 350 hp and 44 passenger seats, including the passive rear steering system. The order states a front axle rating of 17,000 lb, a drive axle rating of 27,500 lb and a tag axle rating of 16,500 lb. 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, all in one answer. The passive rear steering system is listed for the J4500 only; it is not listed (N/A) for the J3500. The order states a front axle rating of 17,000 lb; the brochure lists 14,500 lb for this model. The order states a tag axle rating of 16,500 lb; the brochure lists a 16,500 lb tag axle for the J4500 only and none for the J3500.
    6. 
      
  6. The validator returned three 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 order are checked against each other.
    7. 
      
  7. What this shows: for a stated rating checked against the listed one, a rules-based CPQ can do this only with workarounds.
    8. 
      
  8. Now the agent resubmits.
    9. 
      
  9. The corrected request. It changes the stated front axle rating to 14,500 lb. It removes the passive rear steering and stated tag axle rating.
    10. 
      
  10. It calls the validator again.
    11. 
      
  11. This time the validator clears it.
    12. 
      
  12. All three earlier findings are cleared.
    13. 
      
  13. Three 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.
    14.
