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

An AI sales agent prepares an order for an Irizar i6S integral coach: body length and height, engine, gearbox, retarder, a third steering axle, toilet, kitchen, bunk, wheelchair lift, seats and the figures it states for the coach. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the i6S and returns a verdict, every reason and the figures it computed. The length, height, luggage, engine, gearbox and option lists follow Irizar's public i6S page; the compatibility and seat rules are modeled from comparable coaches, not published by Irizar.

Scope: Irizar i6S integral coaches: length and height, engine, gearbox, retarder, third steering axle, toilet, kitchen, bunk, wheelchair lift and seats (modeled rules). See everything this validator covers

This validator models orders for the Irizar i6S integral coach, not just the scenarios shown below. The offered lengths, heights, luggage volumes, width, engines, gearboxes, retarders and option names follow Irizar's public i6S page; the compatibility, seat-count and approval rules are modeled from comparable coaches and are not Irizar's published rules.

  • Body — 10.78 m, 12.20 m, 12.92 m and 13.20 m lengths in the listed length and height pairings (3.731 m or 3.931 m), a 2,550 mm width and the listed luggage volume for each pairing.
  • Drivetrain — MX-11 (271, 291, 320) and MX-13 (340, 375) engines, ZF Ecolife or ZF AS Tronic gearboxes, ZF Power Retarder or Power Intarder, and the optional third steering axle.
  • Interior options — toilet, kitchen, driver bunk and wheelchair lift, each limited by body length in this model.
  • Seats and stated figures — the seat count against what the body takes, and the luggage volume and width the order states.

Any order for the i6S that touches these rules is in scope — not only the scenarios pictured here. Not covered: prices (this validator produces no price build-up or line-item quote), other Irizar models (i8, i6, i4, ie bus and others), the on-chassis versions, and market-specific homologation. Modeled, not published by Irizar: which engines and gearboxes pair, the Intarder pairing, which bodies take the third axle, toilet, kitchen, bunk and wheelchair lift, the seat limits per body, and the approval for the smallest engine on the longest body. Taken from Irizar's public i6S page: the lengths, heights, luggage volumes, width, engine ratings, gearboxes, retarders and option names.

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
Lengths that exist only with certain heightsOnly with care
A table of valid length and height pairs and a rule reading it.		The length and height are in one request; every pairing is checked on each call.
Engine, gearbox and retarder pairingsOnly with care
One compatibility rule per pairing, kept in step as engines are added.		All three choices arrive together and each pairing is checked.
Options that depend on body length, and a seat limit that falls with each optionOnly with workarounds
Rules per option plus a formula that lowers the seat limit for the toilet and lift.		The seat limit is computed from length and options and compared with the order.
A stated luggage volume or width that disagrees with the listed figureOnly with workarounds
Derived values need extra formulas to compare with what the order states.		The stated figures are fields in the request and are compared with the computed ones.
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 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 i6S is listed at 10.78 m and 12.92 m with a 3.731 m height, at 12.20 m with a 3.731 m or 3.931 m height, and at 13.20 m with a 3.931 m height; this length and height are not listed together.
2The 12.9 litre MX-13 engines are specified here for coaches of 12.20 m and longer; the 10.78 m body takes the MX-11 engines.
3The ZF Ecolife 6-speed automatic is paired here with the MX-11 engines; the MX-13 engines take the ZF AS Tronic 12-speed.
4The ZF Power Intarder is specified here with the ZF AS Tronic gearbox, not the Ecolife.
5The optional third steering axle is specified here for the 12.92 m and 13.20 m bodies only.
6A toilet is specified here for bodies of 12.20 m and longer; the 10.78 m body has none.
7A kitchen is specified here for the 12.92 m and 13.20 m bodies only.
8A driver bunk is specified here for the 12.92 m and 13.20 m bodies only.
9A wheelchair lift is specified here for bodies of 12.20 m and longer.
10The order has 54 seats; this body, with the toilet and wheelchair lift chosen, takes up to 53 seats.
11The order has 51 seats; this body, with the toilet and wheelchair lift chosen, takes up to 50 seats.
12The order has 49 seats; this body, with the toilet and wheelchair lift chosen, takes up to 48 seats.

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 an Irizar i6S integral coach: body length and height, engine, gearbox, and more. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the i6S and returns a verdict, every reason and the figures it computed. The length, height, luggage, engine, gearbox and option lists follow Irizar's public i6S page; the compatibility and seat rules are modeled from comparable coaches, not published by Irizar.
    2. 
      
  2. I will start with the first request by the agent.
    3. 
      
  3. The agent says. Please prepare an order for an Irizar i6S, 10.78 m long and 3.731 m high, with the MX-13 340 engine and the ZF Ecolife gearbox. The order states a luggage volume of 6,500 litres and a body width of 2,550 mm. The rest of the request is on screen.
    4. 
      
  4. Before it goes out, the agent calls the validator.
    5. 
      
  5. Blocked, with four findings, all in one answer. The 12.9 litre MX-13 engines are specified here for coaches of 12.20 m and longer; the 10.78 m body takes the MX-11 engines. The ZF Ecolife 6-speed automatic is paired here with the MX-11 engines; the MX-13 engines take the ZF AS Tronic 12-speed. A toilet is specified here for bodies of 12.20 m and longer; the 10.78 m body has none. The other one is on screen.
    6. 
      
  6. The validator returned four 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 engine, gearbox and retarder pairings, a rules-based CPQ is error-prone for this.
    8. 
      
  8. Now the agent resubmits.
    9. 
      
  9. The corrected request. It changes the length to 12.20 m, the engine to MX-11 320, the gearbox to ZF AS Tronic and the stated luggage volume as to 9,100 litres.
    10. 
      
  10. It calls the validator again.
    11. 
      
  11. This time the validator clears it.
    12. 
      
  12. All four earlier findings are cleared, and the validator's figure matches the order.
    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.
