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

An AI sales agent prepares an order of tilt and turn hardware for a window maker: which hardware range, the frame material, the sash width, height and weight, and the sash capacity the order promises. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the published SIEGENIA hardware limits and returns a verdict, every reason and the figures it computed.

Scope: SIEGENIA tilt and turn and lift and slide hardware: TITAN AF, ALU 5200, ALU axxent PLUS and PORTAL HS 4.0, with frame material, hinge groove, sash size and weight limits. See everything this validator covers

This validator models an order of SIEGENIA window and door hardware from five product lines, based on the published SIEGENIA UK features and benefits insert (October 2023), not just the scenarios shown below.

  • Frame material — TITAN AF is listed for timber, PVC and aluminium (16 mm groove); ALU 5200 and ALU axxent PLUS for aluminium; PORTAL HS 4.0 for timber.
  • Sash size — each range has its own width and height limits, for example 230 to 1650 mm wide and 434 to 3000 mm high for TITAN AF face fixed, and 380 to 1600 mm wide and 550 to 2800 mm high for ALU axxent PLUS. PORTAL HS 4.0 is listed up to 10,000 mm wide and 2800 mm high, with no minimum given.
  • Sash weight — 130 kg for TITAN AF face fixed, 150 kg for TITAN AF axxent 24+ (185 kg with the additional load transfer cable, which needs a person to confirm), 170 kg for ALU 5200, 150 kg for ALU axxent PLUS and 400 kg for PORTAL HS 4.0.
  • Grooves and the stated capacity — ALU axxent PLUS concealed hinges are listed for the A0004 and A0006 aluminium grooves, TITAN AF on aluminium for the 16 mm groove, and the sash capacity the order states must match the hardware.

Any order of these five hardware ranges that touches these limits is in scope — not only the scenarios pictured here. Not covered: prices (SIEGENIA publishes none, so this page shows no price build-up), other SIEGENIA products and ranges, sash weight limits that depend on other conditions in the insert, and fitting or installation.

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
Limits that depend on the hardware range chosenOnly with workarounds
Each range has its own width, height and weight limits. A rules-based CPQ needs a table or a rule per range, and every product update means editing them.		The range, the sash size and the sash weight arrive in one request and are compared with that range's limits on every call.
A weight limit that changes with an add-onOnly with care
The 150 kg limit becomes 185 kg only when the load transfer cable is added, so a rule must read the add-on and the weight together, and flag the order for a person.		The cable, the weight and the limit are evaluated together, and the order is flagged for approval.
Hardware available only for some frame materials and groovesOnly with care
A dependency between the range, the frame material and the groove is a cross-line rule that has to be kept in step with the catalog.		Range, material and groove are checked together on every call.
Capacity that the order statesOnly with care
The stated capacity is a free-entry field; a rule can compare it with the computed limit, but only if the limit itself is computed.		The stated capacity travels with the order and is compared with the computed limit on every call.
Every problem returned in one answerOnly with workarounds
Rules tend to fire as the order is saved or a step is completed, so a person 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.

    
1A sash width of 229 mm is less than the 230 mm minimum of the chosen hardware.
2A sash width of 1651 mm is more than the 1650 mm maximum of the chosen hardware.

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 of tilt and turn hardware for a window maker: which hardware range, the frame material, the sash width, and more. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the published SIEGENIA hardware limits 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 place an order of ALU axxent PLUS hardware for Northgate Façades, for 16 aluminium sashes, each 1,000 mm wide. The order states a sash capacity of 150 kg. 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, all in one answer. ALU axxent PLUS concealed hinges are listed for the A0004 and A0006 aluminium grooves; another groove was chosen. A sash height of 500 mm is less than the 550 mm minimum of the chosen hardware.
    6. 
      
  6. The validator returned two 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 hardware available only for some frame materials and grooves, a rules-based CPQ is error-prone for this.
    8. 
      
  8. Now the agent resubmits.
    9. 
      
  9. The corrected request. It changes the aluminium groove to A0004.
    10. 
      
  10. It calls the validator again.
    11. 
      
  11. Still blocked, with one finding, all in one answer. A sash height of 500 mm is less than the 550 mm minimum of the chosen hardware.
    12. 
      
  12. One finding cleared. Still blocking: sash lower than the hardware allows.
    13. 
      
  13. The agent resubmits once more.
    14. 
      
  14. The revised request. It changes the sash height to 1,400 mm.
    15. 
      
  15. It calls the validator once more.
    16. 
      
  16. This time the validator clears it.
    17. 
      
  17. The earlier finding is cleared, and the validator's figure matches the quote.
    18. 
      
  18. Two 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. Now you can try the other scenarios yourself.
    19.
