An AI sales agent's elevator quote, checked against the shaft before it goes out

An AI sales agent prepares a quote for a synergy 100 passenger elevator: the rated load and cabin, the entrance and door, the door arrangement, the shaft the building has, the pit, the head, the speed and the number of passengers the quote states. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the published product brochure and returns a verdict, every reason and the minimum shaft it computed.

Scope: TK Elevator synergy 100 passenger elevator: cabin and load, entrance and door, shaft width and depth, pit, head, speed, stated passengers. See everything this validator covers

This validator models quotes for the synergy 100 passenger elevator at 1.0 m/s (and flags 1.6 and 1.75 m/s), not just the scenarios shown below. It follows the dimensions chart and the shaft layout in the public TK Elevator synergy 100 brochure.

  • Cabin and load — the 450 kg, 630 kg and 1000 kg rated loads, each with the cabin sizes the chart lists for it, and the passenger count listed for the load (6, 8 and 13).
  • Entrance and door — single or double entrance, side-opening (L2) or central-opening (C2) doors with 2 panels, and the door widths the chart lists for that combination; a combination the chart does not list is blocked.
  • Shaft size — the minimum shaft width and depth for the cabin, entrance, door and door arrangement (recess, full front, partially in shaft or in shaft); a shaft that is even 1 mm too narrow or too shallow is blocked.
  • Pit, head, car height and speed — a standard pit of 1000 mm and head of the car height plus 1200 mm; the brochure's reduced pit (from 425 mm) and reduced head (car height plus 490 mm, for a 2070 mm car) are sent to a person to confirm; car heights from 2070 to 2500 mm; speeds of 1.6 and 1.75 m/s are flagged because the chart is for 1.0 m/s.

Any quote for this product line is in scope — not only the scenarios pictured here. Not covered: prices (none are public, so no price build-up), other TK Elevator elevator models, the maximum travel height, machine room or equipment details, and local codes. The brochure says its values are for a generic installation and TK Elevator must confirm guaranteed shaft dimensions for a project.

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 minimum shaft width and depth that depends on cabin, entrance, door type, door width and door arrangementOnly with care
The chart has dozens of rows, and the depth changes again with the door arrangement, so a rep can quote a shaft that is a few millimeters short for the arrangement chosen.		The minimum width and depth are looked up from the combination on every call and compared with the shaft on the quote.
Combinations the chart does not listOnly with workarounds
A 900 mm central-opening door on the smallest cabin, or a full front arrangement with no listed values, needs its own exclusion rule for each gap.		Anything not in the chart is blocked, with the reason.
Reduced pit and reduced head that are allowed only with a person confirmingOnly with care
Pit and head each have a standard value, a reduced option that only applies to a 2070 mm car, and a floor below which nothing is offered, so the rules overlap.		Standard passes, reduced values need confirmation, and values below the floor are blocked.
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

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 shaft is 1494 mm wide; this cabin and door need at least 1495 mm.

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 synergy 100 passenger elevator: the rated load and cabin, the entrance and door, the door arrangement, and more. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the published product brochure and returns a verdict, every reason and the minimum shaft it computed.
    2. 
      
  2. I will start with the first request by the agent.
    3. 
      
  3. The agent says. Please quote a synergy 100 passenger elevator rated for 630 kg with a 1100 x 1400 mm cabin, a double entrance with central-opening 2-panel doors 900 mm wide. The shaft is 1850 mm wide and 1800 mm deep, with a 900 mm pit and a 3400 mm head. The rest of the request is on screen.
    4. 
      
  4. Before it goes out, the agent calls the validator.
    5. 
      
  5. Blocked, with two findings and one approval, all in one answer. The shaft is 1850 mm wide; this cabin and door need at least 1980 mm. The shaft is 1800 mm deep; this cabin, door and door arrangement need at least 1850 mm.
    6. 
      
  6. The validator returned two blocking findings and one approval 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 reduced pit and reduced head that are allowed only with a person confirming, a rules-based CPQ is error-prone for this.
    8. 
      
  8. Now the agent resubmits.
    9. 
      
  9. The corrected request. It changes the shaft width to 2,000 mm, the shaft depth to 1,870 mm and the pit to 1,000 mm.
    10. 
      
  10. It calls the validator again.
    11. 
      
  11. This time the validator clears it.
    12. 
      
  12. All three earlier findings are cleared, and the validator's figure matches the quote.
    13. 
      
  13. Three 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.
