Predictika · Window and door quotes

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

An AI sales agent configures an order of windows and sliding doors: the window system, exterior and interior surfaces, opening type, glazing and size, with the installation method. Before the quote goes out, the agent sends it to Predictika, which checks it against a declarative model, compares the glazed element weight the agent states with the one it computes, and returns a verdict, every reason and the figures it computed.

Scope: Finstral FIN-Window and FIN-72 window systems, wood-aluminum windows, FIN-Slide and FIN-Scroll doors: surfaces, glazing, size, weight and installation. See everything this validator covers

This validator models orders for Finstral windows and sliding doors built from Finstral product names, not just the scenarios shown below.

  • Window systems — FIN-72 Classic-line 72 (all PVC), FIN-Window Classic-line C 90+8, Nova-line Twin N 90+8, FIN-72 Nova-line 72+8 and the Slim-line (PVC with an aluminum exterior), and the wood-aluminum windows.
  • Surfaces — PVC or aluminum exteriors in plain colors or wood decors, dark tones only as aluminum cladding, and a PVC, soft wood or hard wood interior.
  • Openings and glazing — fixed, tilt-and-turn, balcony door, FIN-Slide and FIN-Scroll elements, with double or Max-Valor triple glazing, sized against the weight each opening type can carry.
  • Installation and order size — slide-on installation or a FIN-Fix mounting frame, and the size and quantity of the order, with large elements and project orders sent to a person.

Any Finstral window or sliding door order that touches these rules is in scope, not only the scenarios pictured here. Product names are Finstral's own public names. The size limits, weight limits, which system takes which options and the approval thresholds are modeled from comparable window systems and are not Finstral-published rules. Not covered: prices (this validator produces no price build-up or line-item quote), entry doors, FIN-Fold, FIN-Vista window walls, shutters, sun protection and other accessories, and other Finstral product lines.

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
Which surfaces and interiors each system takesOnly with care
A product rule per system and surface works, but every new system or finish is more rules to maintain and keep consistent.		Each system, exterior and interior is checked together on every call.
Glazed element weight against what the opening can carryOnly with workarounds
The weight depends on width, height and glazing on the same line and is compared with a limit that depends on the opening type; it needs a calculation field and a comparison rule that interact.		Weight is computed from size and glazing and compared with the opening limit on every call.
Stated weight that must match the glassOnly with care
A stated figure is a free-entry field; a rule can compare it with a computed one, but someone has to write and maintain that comparison.		The stated weight travels with the quote and is compared with the computed weight on every call.
Installation method against a mounting frameOnly with care
A cross-option rule; it works, but it is one of many that must be kept in step.		Installation method and mounting frame are checked together.
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.

The text of the narrated walkthrough, step by step.

    
    
      
  1. Welcome to a demo of Predictika's Validator. An AI sales agent configures an order of windows and sliding doors: the window system, exterior and interior surfaces, opening type, and more. Before the quote goes out, the agent sends it to Predictika, which checks it against a declarative model, compares the glazed element weight the agent states with the one it computes, 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 quote 24 tilt-and-turn windows on the FIN-Window Nova-line Twin N 90+8, 110 by 130 centimeters, with a dark-tone PVC exterior in a wood decor and a hard wood interior. Each glazed element weighs 28,600 grams. 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. Dark tones are offered only as aluminum cladding; the quote has a dark tone on a PVC exterior. This system has an aluminum exterior; the quote has a PVC exterior. A wood interior is only offered on the wood-aluminum windows; the quote has a wood interior on another system.
    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 quote are checked against each other.
    7. 
      
  7. What this shows: for which surfaces and interiors each system takes, a rules-based CPQ is error-prone for this.
    8. 
      
  8. Now the agent resubmits.
    9. 
      
  9. The corrected request. It changes the exterior to aluminum exterior in a plain color.
    10. 
      
  10. It calls the validator again.
    11. 
      
  11. Still blocked, with one finding, all in one answer. A wood interior is only offered on the wood-aluminum windows; the quote has a wood interior on another system.
    12. 
      
  12. Two findings cleared. Still blocking: wood interior needs the wood-aluminum system.
    13. 
      
  13. The agent resubmits once more.
    14. 
      
  14. The revised request. It changes the window system to wood-aluminum window.
    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. Three 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.
