An AI sales agent's tilt and turn hardware order, checked before it goes out

An AI sales agent prepares an order for the concealed tilt and turn hardware of an aluminium window or patio door sash: the sash size and weight, the opening angle, the hinge-side set and the extra components the size and weight call for. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the manufacturer's assembly instructions and returns a verdict, every reason and the figures it computed.

Scope: SIEGENIA ALU axxent PLUS-DK concealed tilt and turn hardware for single-sash square aluminium windows and patio doors (eurogroove 15/20). See everything this validator covers

This validator models orders for the SIEGENIA ALU axxent PLUS-DK hardware (single-sash square tilt and turn, aluminium eurogroove 15/20, chamber dimension 21, profile versions A0004, A0006 and A0022) as set out in SIEGENIA assembly instructions H48.axntLS010EN-10 (10.2022), not just the scenarios shown below.

  • Size, weight and angle — windows 450 to 1600 mm wide and 600 to 2000 mm high, patio doors 450 to 1300 mm wide and 2000 to 2600 mm high; sash weight classes of 100, 130 and 150 kg (no heavier sash); an opening angle of at most 110 degrees, and at most 90 degrees above 130 kg.
  • Hinge-side set — size 1 only for a sash up to 600 mm wide and 100 kg, otherwise size 2, by profile version and hand; the validator names the article number and checks that the quote has the right size and that the stated weight class matches the sash.
  • Components the size and weight call for — the additional stay (over 1250 mm wide, or over 1020 mm wide and over 100 kg), the accessory set over 100 kg, the centre lock (MV) over 1250 mm high, the MV slider over 1250 mm wide, and the short or long sash brake with damper over 130 kg (850 to 1000 mm and over 1000 mm wide).
  • Handles and sets — Si-line and Globe handles go with a coupling set (chosen by rebate height and dimension Y), TITAN and Globe RR handles with the gear set; the A0022 profile version needs the A0022 accessory set, which goes only with the A0006 hinge-side set.

Any order for this hardware that touches these rules is in scope — not only the scenarios pictured here. Not covered: prices (the assembly instructions list article numbers and pack sizes, not prices, so this validator produces no price build-up or line-item quote), other SIEGENIA hardware (TITAN AF, the turn-only ALU axxent PLUS-D/ZV, other ALU systems, timber and PVC hardware, sliding doors), double-sash and non-square windows, and top stay sizes, locking parts for sashes over 2400 mm high and installation positions. Assumptions: an item listed with a condition in the hardware list (for example “FB > 1250”) is treated as required when the condition holds; the A0022 accessory set is treated as required for the A0022 profile version; and combinations of rebate height and dimension Y for which the document lists no coupling set are blocked.

The AI sales agentBuilds the hardware order from the conversation and says it is ready.

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
Components that become mandatory from the sash width, height and weightOnly with care
Each component has its own threshold, some on width, some on height, some on width and weight together, so a product rule is needed per component and a change to one threshold is easy to miss in the others.		All thresholds are computed from the sash size and weight on every call and compared with what is on the quote.
Hinge-side set size and sash brake length that follow from size and weight bandsOnly with care
The correct variant depends on two or three quantities at once, so a rule must be written for each band and checked against the variant on the order.		The required variant is derived on every call and compared with the one quoted.
A stated weight class that must match the sash weight, and an opening angle limit that depends on that weightOnly with workarounds
The stated class is a free field that has to be compared with a class derived from the weight, and the angle limit is a second, weight-dependent rule on a different line.		The stated class and the angle are part of the request and are checked against the derived class and limits on every call.
Handle families that need a particular set, with set variants chosen by rebate height and dimension YOnly with workarounds
The pairing and the table lookups span several lines and every new handle or set variant adds rules that interact with the others.		The handle, the sets and the rebate dimensions are in one request and the pairing and lookups are checked together.
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.

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 the concealed tilt and turn hardware of an aluminium window or patio door sash: the sash size and weight, the opening angle, the hinge-side set and the extra components the size and weight call for. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the manufacturer's assembly instructions 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 the ALU axxent PLUS-DK tilt and turn hardware set for an aluminium window sash 1,400 mm wide and 1,900 mm high weighing 140 kg. The sash opens to 100 degrees. The rest of the request is on screen.
    4. 
      
  4. Before it goes out, the agent calls the validator.
    5. 
      
  5. Blocked, with six findings, all in one answer. A sash of 140 kg may open to at most 90 degrees, but the opening angle is 100 degrees. The quote states the 130 kg weight class, but a sash of 140 kg needs the 150 kg class. A sash 1,400 mm wide and 140 kg needs the additional stay, which is not on the quote. The other three are on screen.
    6. 
      
  6. The validator returned six 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 a stated weight class that must match the sash weight, and an opening angle limit that depends on that weight, a rules-based CPQ can do this only with workarounds.
    8. 
      
  8. Now the agent resubmits.
    9. 
      
  9. The corrected request. It changes the opening angle to 90 degrees, the additional stay to yes, the accessory set to yes, the MV slider to yes, the sash brake with damper to long and the stated weight class to 150 kg.
    10. 
      
  10. It calls the validator again.
    11. 
      
  11. This time the validator clears it.
    12. 
      
  12. All six earlier findings are cleared, and the validator's figure matches the quote.
    13. 
      
  13. Six 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.
