Predictika · Window and lift-slide door orders

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

An AI sales agent prepares an order for PVC windows, balcony doors and a terrace lift-slide door: an IGLO system, the unit type, sash size, glazing thickness, profile colour, spacer, delivery time and a stated Uw value. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the product line and returns a verdict and every reason.

Scope: Drutex IGLO 5 Classic, IGLO Energy, IGLO Edge, IGLO Premier and IGLO HS: windows, balcony doors, fixed glazing and the terrace lift-slide door. See everything this validator covers

This validator models Drutex IGLO window and door orders, not just the scenarios shown below.

  • Systems and units — which unit types each IGLO system takes: the lift-slide door only on IGLO HS, no balcony door on IGLO Premier, and window units on the other systems.
  • Glazing and size — the glazing thickness each system accepts, maximum sash width and height, fixed glazing size, the sash lifter on tall IGLO 5 Classic sashes, and the weight of a lift-slide leaf.
  • Colour and spacer — the profile colours each system is ordered in, veneers, and the warm-edge spacer that IGLO HS glazing uses.
  • Stated figures and approvals — the Uw value stated on the order against the value the system lists, large orders, rush orders and veneers on IGLO HS that a person must confirm.

Any Drutex IGLO order that touches these rules is in scope — not only the scenarios pictured here. Not covered: IGLO Light, IGLO Energy Classic, PSK variants, aluminum lines, prices and taxes. The validator produces no price build-up.

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 unit goes with which systemOnly with care
Each IGLO system takes some unit types and not others, so every pairing needs its own compatibility rule.		The system and the unit are fields of one order and are checked together on every call.
Limits that differ by systemOnly with care
Glazing thickness and sash size limits change with the system, so each limit needs a version for every system.		The system, glazing and sash size are in one order and compared on every call.
A lift-slide leaf weight computed from glassOnly with workarounds
The leaf weight is derived from size and glazing, so a separate formula rule is needed before the 400 kg limit can be checked.		The weight is computed from the order fields and compared with the limit on every call.
A stated Uw that must match the systemOnly with workarounds
A rule has to look up the system value and compare it with the figure on the order for each system.		The stated value is a field of the order and is compared with the system value 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 rep often fixes one error and meets the next.		All findings come back together, whatever order the choices arrived in.

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 PVC windows, balcony doors and a terrace lift-slide door: an IGLO system, the unit type, sash size, and more. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the product line and returns a verdict and every reason.
    2. 
      
  2. I will start with the first request by the agent.
    3. 
      
  3. The agent says. Please order 120 tilt-turn window units in IGLO Energy, each 1,450 mm wide and 1,400 mm high, with 56 mm glazing, an anthracite profile and a steel spacer. Delivery is in 3 weeks. The rest of the request is on screen. The Uw value is 0.86.
    4. 
      
  4. Before it goes out, the agent calls the validator.
    5. 
      
  5. Blocked, with four findings and one approval, all in one answer. The glazing package is 56 mm thick; the system on the order takes up to 52 mm. The sash is 1,450 mm wide; the system on the order takes sashes up to 1,400 mm. IGLO Energy profiles come in white or brown; use a veneer for an anthracite look. The other one is on screen.
    6. 
      
  6. The validator returned four 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 order are checked against each other.
    7. 
      
  7. What this shows: for limits that differ by system, a rules-based CPQ is error-prone for this.
    8. 
      
  8. Now the agent resubmits.
    9. 
      
  9. The corrected request. It changes the width to 1,400 mm, the glazing to 52 mm, the profile colour to brown, the delivery to 6 weeks and the Stated Uw value to 0.71.
    10. 
      
  10. It calls the validator again.
    11. 
      
  11. This time the validator clears it.
    12. 
      
  12. All five earlier findings are cleared.
    13. 
      
  13. Five problems caught in one call, fixed in one pass, and a clean order. That is the value of Predictika's validator: catching mistakes before they reach the customer. Now you can try the other scenarios yourself.
