Predictika · Aluminium window and door orders

An AI sales agent's aluminium window and door order, checked before it goes out

An AI sales agent prepares an order for an aluminium window or door from a published system variant: the type, the sash or door size, the glass thickness, the burglar resistance class and the performance figures it states on the quote. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the published system datasheet and returns a verdict, every reason and the listed size limit it compared against.

Scope: Four published MB-86 variants (MB-86N, MB-86B, MB-86US, MB-86 Casement): listed window and door types, maximum sizes, glass thickness, security class and stated performance. See everything this validator covers

This validator models the technical specification published in the Aluprof MB-86N datasheet for these four variants, not just the scenarios shown below.

  • Types and sizes — each variant lists the window and door solutions it offers and a maximum sash or door height and width, separately for windows and doors; an unlisted type or a size above the listed maximum is blocked.
  • Glass — each variant lists a glazing thickness range for glass in the frame (fixed windows) and in the sash; a thickness outside the range is blocked. No door glazing range is given in the datasheet, so none is checked.
  • Security — the datasheet lists anti-burglary windows and doors up to RC4; a class above RC4 is blocked.
  • Stated performance — a stated U value better than the best value listed for the MB-86N, a U value or impact class stated where the datasheet lists none, an impact class above the listed class 3, or an air permeability class above the listed class 4 goes to a person for approval, because the listed figures are for reference sizes and glazing.

Any order for these four variants that touches these rules is in scope — not only the scenarios pictured here. Not covered: prices (Aluprof publishes no price list, so this validator produces no price build-up or line-item quote), water tightness and wind load classes (the datasheet table is ambiguous), thermal profile versions, colours, hardware and fabrication details, and other Aluprof systems.

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 differ by variant and by window or doorOnly with care
Each variant has its own maximum height and width, one set for windows and another for doors, so each needs its own product rules and the numbers have to be kept in step with the datasheet.		The variant and type are inputs; the limits for that combination are computed on each call and checked in the same pass.
Opening types that exist only on some variantsOnly with workarounds
Whether a hopper, awning or door is available depends on the variant chosen on another line, so it needs cross-line rules that interact with the rest.		Every choice is in one request, so a type the variant does not list is found whichever order the choices arrive in.
Glass ranges that depend on where the glass sitsOnly with care
The allowed thickness changes with the variant and with whether the glass is in the frame or the sash, so each combination needs its own comparison.		The glazing position follows from the type, and the right range is applied on every call.
Stated performance figures that the datasheet lists only for some variantsOnly with care
A U value or impact class is listed for some variants and not others, so each claim needs its own formula and a person to confirm any claim the datasheet does not support.		The listed values are computed on every call and compared with the figures the quote states; an unsupported claim goes to approval.
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.

  

  

    
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.

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 aluminium window or door from a published system variant: the type, the sash or door size, the glass thickness, and more. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the published system datasheet and returns a verdict, every reason and the listed size limit it compared against.
    2. 
      
  2. I will start with the first request by the agent.
    3. 
      
  3. The agent says. Please quote an MB-86 Casement hopper window, 2500 mm wide and 1400 mm high, with 36 mm glass. It is ready to send.
    4. 
      
  4. Before it goes out, the agent calls the validator.
    5. 
      
  5. Blocked, with two findings, all in one answer. The sash or door width is 2,500 mm; the listed maximum for this variant and type is 2,400 mm. The datasheet does not list the requested window or door type among the solutions for this variant.
    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 limits that differ by variant and by window or door, a rules-based CPQ is error-prone for this.
    8. 
      
  8. Now the agent resubmits.
    9. 
      
  9. The corrected request. It changes the type to awning window and the sash or door width to 2,300 mm.
    10. 
      
  10. It calls the validator again.
    11. 
      
  11. This time the validator clears it.
    12. 
      
  12. Both earlier findings are cleared.
    13. 
      
  13. Two 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.
