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

An AI sales agent prepares an order for Essential double hung windows from the public Marvin technical specifications: the call size, sash configuration, glass, egress listing, site altitude and grilles. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of those published tables and returns a verdict, every reason and the figures it computed.

Scope: Marvin Essential double hung windows (single units): call sizes, sash configuration, glass and altitude limits, egress listing and grilles-between-the-glass. See everything this validator covers

This validator models single Essential double hung window orders using the public Marvin Essential Technical Specifications catalog and the Essential double hung elevations sheet, not just the scenarios shown below.

  • Call sizes — the seven listed width calls (16 to 40) and ten height calls (20 to 66), with the rough opening each one gives.
  • Sash configuration — equal, cottage and reverse cottage sash, and the rule that cottage sashes are not made at the 20, 60 and 66 call heights.
  • Egress — the units the catalog lists as meeting national egress codes (5.7 sq ft, 20 in. clear width, 24 in. clear height, equal sash only), the 44 in. floor-to-sill limit, and the egress rating stated on the order.
  • Glass and altitude — the maximum site altitude Marvin lists for each size with annealed or tempered glass, in the standard and the sound-rated (STC/OITC) glass packages, and the altitude limit stated on the order.
  • Grilles — the standard rectangular grilles-between-the-glass cut, with other lite cuts sent to a person.

Any single Essential double hung unit order is in scope — not only the scenarios pictured here. Not covered: prices (Marvin publishes no Essential price list, so this validator produces no price build-up), mulled and multiple-unit assemblies, other Marvin products and collections, finishes and hardware, performance grades and local code. Assumptions: the sound-rated altitude table is taken to apply to the STC/OITC glass package, and the egress units are taken from the equal-sash egress table.

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
Sizes that exist and the sashes made in themOnly with care
A size matrix of seven widths and ten heights, with a sash rule that depends on the height, to keep in step with the catalog.		The listed sizes and the sash availability by height are checked together on every call.
Egress from size, sash and sill heightOnly with workarounds
A list of egress sizes that depends on sash type, plus a separate sill-height rule.		The egress listing, the sash type and the 44 in. sill limit are checked together and each failure is reported.
Altitude limit by size, glass and glass packageOnly with workarounds
A lookup of about 280 values across size, annealed or tempered glass and two glass packages, and an extra rule to compare the site with it.		The listed limit is looked up from the size and glass and compared with the site altitude on every call.
A stated figure that disagrees with the catalogOnly with workarounds
The stated egress rating and altitude limit are separate fields and each needs its own rule against the published figure.		Each stated figure is part of the request and is compared with the listed figure on every call.
A choice that depends on product type and sizeOnly with workarounds
Rules know pass or fail; a lite cut that needs confirming has to be built as a special rule.		It goes to a person as needs approval, neither passed nor blocked.
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.

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 Essential double hung windows from the public Marvin technical specifications: the call size, sash configuration, glass, and more. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of those published tables 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 6 Essential double hung windows, width call 30 by height call 50, cottage sash, annealed standard glass, as bedroom egress windows with the clear opening 48 in. above the floor. The order states that the unit meets national egress codes. The rest of the request is on screen. It states an altitude limit of 8,000 ft.
    4. 
      
  4. Before it goes out, the agent calls the validator.
    5. 
      
  5. Blocked, with three findings, all in one answer. Egress is required, but only equal sash double hung units are listed as meeting egress codes; cottage and reverse cottage units are not. Egress is required, but the clear opening is 48 in. above the floor; the egress listing is for a floor to sill height of 44 in. at most. The quote states egress rating 1 (1 means meets egress codes, 0 means does not), but the catalog listing for this unit gives 0.
    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 egress from size, sash and sill height, 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 equal sash and the clear opening above floor to 42.
    10. 
      
  10. It calls the validator again.
    11. 
      
  11. This time the validator clears it.
    12. 
      
  12. All three earlier findings are cleared.
    13. 
      
  13. Three 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.
