Predictika · Window and door orders

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

An AI sales agent prepares an order for triple-glazed windows and lift and slide doors: the series, design style, opening type, glazing, security class, blinds and extras. Before the order goes out, the agent sends it to Predictika, which checks it against a declarative model, compares the thermal and noise figures the agent states with what the series reaches, and returns a verdict, every reason and the figures it computed.

Scope: Internorm uPVC-aluminium and timber-aluminium windows, lift and slide doors and panorama glazing (KF, KV, HF, HV, KS, HS and HX series): styles, openings, glazing, security, blinds and size. See everything this validator covers

This validator models orders for Internorm windows and doors built from Internorm product names and the figures in its public UK brochure, not just the scenarios shown below.

  • Series and styles — KF 510, KF 410, KF 310, KV 440, KV 350, HF 510, HF 410, HV 450, KS 430, HS 330 and HX 300, with the design styles home pure, home soft, ambiente and studio offered for each series.
  • Openings and glazing — fixed, turn and tilt, sliding window, doors, low-threshold doors, outward-opening doors and lift and slide doors, by series; triple glazing, laminated or toughened safety glass, Juliet balconies and low glazing.
  • Performance and security — the best Uw, the highest noise reduction and the highest security class (RC1N, RC2, RC3) each series reaches, compared with what the order states; RC3 is available on request.
  • Options — blinds between the panes with I-tec Shading (KV and HV series), I-tec Ventilation, lockable handles, Comfort Drive on lift and slide doors, timber and uPVC interiors, lift and slide sash weight (up to 400 kg), lift and slide size (up to 650 x 280 cm) and panorama glazing (up to 10.5 square metres).

Any Internorm window or door order that touches these products and rules is in scope, not only the scenarios pictured here. Product names, Uw, noise, security, opening types, design styles and the lift and slide and panorama limits come from the Internorm UK brochure. The size limits of the other series, the compatibility rules not stated there (for example which series take I-tec Ventilation, the lockable handle on the KF 510, safety glass for low glazing) and the discount thresholds are modeled from comparable window systems and are not Internorm-published. Not covered: prices (this validator produces no price build-up or line-item quote), front doors, uPVC-only windows without aluminium, fly screens, shutters and raffstores, colours and handles, and installation.

The AI sales agentBuilds the window and door order from the conversation and says it is ready.
Predictika validatorChecks every rule at once and returns the verdict, each finding, and the computed figures.

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
Design styles that are only offered for some seriesOnly with care
A product rule per style and series; it works, but every new series or style is more rules to maintain.		Style, series and opening are in one request and checked together on every call.
Stated thermal and noise figures that must not beat the seriesOnly with care
A stated figure is a free-entry field; a rule can compare it with a limit, but someone has to write and keep that comparison for every series.		The stated figures travel with the order and are compared with each series on every call.
Safety glass that depends on the opening, the sill height and a Juliet balconyOnly with workarounds
Glass type depends on choices on several lines (opening, sill, balcony), so it needs cross-line rules that interact with each other.		Every choice is in one request, so the conflict is found whichever order the choices arrive in.
Blinds, solar shading and ventilation that only some series takeOnly with workarounds
The options depend on the series and on each other (shading needs a blind), so one change can invalidate another choice.		Series and options are checked together, and each missing dependency is reported.
Lift and slide doors with size, sash weight and glass limitsOnly with care
Several numeric limits for one product family; each works alone, but they have to be kept in step.		Size, weight and glass are checked together and the heavy-sash approval is raised alongside.
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.

    
1The design style on the order is not offered for the chosen series (home pure suits every series; home soft, ambiente and studio are limited to some).
2The opening type on the order is not offered for the chosen series (for example outward-opening doors only come with KF 410, KF 310 and HF 410).
3The order states a Uw of 61 hundredths of W/m2K, better than the 62 the series reaches at best.
4The order states a Uw of 68 hundredths of W/m2K, better than the 69 the series reaches at best.
5The order states a noise reduction of 48 dB, above the 47 dB this series reaches.
6The security class asked for (RC3) is above the highest class the chosen series offers (RC2).
7The highest security class (RC3) is available on request; a person should confirm it with Internorm.
8The KF 510 reaches its higher security classes with its integrated locking and a lockable handle; the order has none.
9Blinds between the glass panes come only with the KV 440, KV 350 and HV 450 series.

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 triple-glazed windows and lift and slide doors: the series, design style, opening type, and more. Before the order goes out, the agent sends it to Predictika, which checks it against a declarative model, compares the thermal and noise figures the agent states with what the series reaches, 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 order 8 Internorm KF 310 units, turn and tilt, 120 x 135 cm with the glass 90 cm above the floor. The order states a Uw of 0.66 W/m2K and a noise reduction of 40 dB. 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 and one approval, all in one answer. The design style on the order is not offered for the chosen series (home pure suits every series; home soft, ambiente and studio are limited to some). The order states a Uw of 66 hundredths of W/m2K, better than the 69 the series reaches at best. The security class asked for (RC3) is above the highest class the chosen series offers (RC2).
    6. 
      
  6. The validator returned three 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 design styles that are only offered for some series, a rules-based CPQ is error-prone for this.
    8. 
      
  8. Now the agent resubmits.
    9. 
      
  9. The corrected request. It changes the series to KF 510, the design style to home pure and the lockable handle to yes.
    10. 
      
  10. It calls the validator again.
    11. 
      
  11. Not blocked, but held for a person.
    12. 
      
  12. The three blocking findings are cleared; one approval remains for a person: RC3 security is on request.
    13. 
      
  13. The agent resubmits once more.
    14. 
      
  14. The revised request. It changes the security class to RC2.
    15. 
      
  15. It calls the validator once more.
    16. 
      
  16. This time the validator clears it.
    17. 
      
  17. The earlier finding is cleared.
    18. 
      
  18. Four 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.
