An AI sales agent's Modus casement window quote, checked before it goes out

An AI sales agent prepares a trade quote for Eurocell Modus casement windows: the sash style, the opening type and size, the glazing, the reinforcing, the sill, the colour and the guarantee. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the public Modus technical data sheets and returns a verdict, every reason and the listed U-value and energy index it compared against.

Scope: Eurocell Modus flush sash and slim rebate sash PVC-U casement windows only: opening type and size limits, glazing units, reinforcing, sills, colours and the guarantee. See everything this validator covers

This validator models rules stated in the public Modus technical data sheets, not just the scenarios shown below.

  • Size limits — top hung, side hung and fixed lights each have a listed width and height range (for example a side hung sash is 400 to 750 mm wide and 320 to 1,500 mm high); a fixed light has listed maximums.
  • Glazing — the listed double and triple glazed units, each with its U-value and window energy index; the figures differ between the flush and slim rebate sash for some units, and the Clearvision unit is listed for the slim rebate sash only. Triple units need full thermal reinforcing.
  • Reinforcing and accessories — steel in transoms between 1,600 and 2,000 Pa; Cavalok cavity closers for 100 to 300 mm cavities; sill depths of 85, 125, 150, 180 and 225 mm.
  • Colour and guarantee — the standard colour range, with architectural and other colours going to a person; the 12-year guarantee applies to the White profile only.

Any quote for these two sash styles that touches these rules is in scope — not only the scenarios pictured here. Not covered: prices (no public Eurocell trade price list was found for these products, so this validator produces no price build-up or line-item quote), the standard casement, tilt and turn windows, doors and the other Eurocell products.

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
Size limits that depend on the opening typeOnly with care
Each opening type has its own width and height range, so every window line needs the right range chosen from its type.		The ranges are held once as data and every window is compared with the range for its own opening type.
Glazing figures that depend on the sashOnly with workarounds
The same glazing unit lists a different U-value and energy index on the flush and slim rebate sash, so a stated figure must be looked up by sash and glazing together.		The model looks up the listed values for the chosen sash and glazing and compares the quote's stated figures with them.
Conditions that come from the choicesOnly with care
Triple glazing needs thermal reinforcing, a transom at high wind load needs steel, and a cavity closer has a cavity range.		These conditions are evaluated together on every call, in whatever order the choices arrive.
Blocks and approvalsOnly with workarounds
A colour or sill that the sources list differently needs a person, which must be told apart from a hard mismatch.		Blocks and approvals are separate findings in one answer, and the Execute step is refused until each one is cleared.
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 prepares a trade quote for Eurocell Modus casement windows: the sash style, the opening type and size, the glazing, and more. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the public Modus technical data sheets and returns a verdict, every reason and the listed U-value and energy index it compared against.
    2. 
      
  2. I will start with the first request by the agent.
    3. 
      
  3. The agent says. Please quote 6 Modus flush sash top hung windows, 1250 mm wide by 1400 mm high, double-glazed (4/20/4, Clearvision and Planibel A, Argon). The quote states a 12-year guarantee. 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 width of 1,250 mm is above the listed maximum of 1,200 mm for this opening type. A height of 1,400 mm is above the listed maximum of 1,350 mm for this opening type. The Clearvision and Planibel A double-glazed unit is listed only for the slim rebate sash, not the flush sash. 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 glazing figures that depend on the sash, a rules-based CPQ can do this only with workarounds.
    8. 
      
  8. Now the agent resubmits.
    9. 
      
  9. The corrected request. It changes the sash to slim rebate sash, the width to 1,200 mm and the height to 1,350 mm. It sets the steel in transom to yes.
    10. 
      
  10. It calls the validator again.
    11. 
      
  11. Still blocked, with two findings, all in one answer. The Cavalok cavity closer is listed for cavities of 100 to 300 mm; the quote has 350 mm. The quote states a 12-year guarantee; the Modus guarantee of 12 years applies to the White profile only.
    12. 
      
  12. Four findings cleared. Still blocking: Cavalok cavity closer size not listed and the 12-year guarantee applies to White only.
    13. 
      
  13. The agent resubmits once more.
    14. 
      
  14. The revised request. It changes the colour to white and the cavity to 300 mm.
    15. 
      
  15. It calls the validator once more.
    16. 
      
  16. This time the validator clears it.
    17. 
      
  17. Both earlier findings are cleared.
    18. 
      
  18. Six 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.
