An AI sales agent's Pleiad G4 downlight order, checked before it goes out

An AI sales agent prepares an order for Pleiad G4 downlights: a variant and diameter, lumen package, colour rendering and temperature, control, beam, protection rating, accessories, sensors, a discount and a net price. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model and returns a verdict, every reason and the figures it computed. The product family, variant names and main options come from public Fagerhult pages; several rules and all prices are modeled for this demonstration and are not Fagerhult's.

Scope: Fagerhult Pleiad G4 downlights (Recessed, Surface, Square Recessed, Robust Recessed): diameter, lumen package, CRI, colour temperature, control, beam, IP rating, accessories, sensors, discount and an illustrative price. See everything this validator covers

This validator models one Pleiad G4 order at a time, not just the scenarios shown below. It separates what is public from what is modeled.

  • Public, from Fagerhult pages — the Pleiad G4 family with Recessed, Surface, Square Recessed and Robust Recessed variants; Surface in 128 and 168 mm; CRI 80 and 90; 3000 K and 4000 K plus Tunable White; DALI and On/Off control; medium, wide and extra wide beams; white or black finish; IP64 only when recessed in a suspended ceiling and IP20 otherwise; Surface 168 accessories (cable pendant, wire suspension, IP23 cover plate, sloping-ceiling cylinder); one Organic Response sensor for at most four luminaires.
  • Modeled, not published as rules by the company — the lumen maximum for each diameter, which diameters the Square Recessed and Robust Recessed variants offer, Tunable White at CRI 80 only, extra wide beam limits, the emergency option limit, sensors needing DALI, the discount limits (10 percent without approval, 30 percent maximum), the project-order and black-finish approvals, and every price.
  • What is checked — variant against diameter, lumen package, CRI and colour temperature, control, beam, protection rating and ceiling, accessories, emergency option, sensors per luminaire, discount, and the net price the agent states, which must equal the computed one.

Any Pleiad G4 order that touches these rules is in scope — not only the scenarios pictured here. Not covered: other Fagerhult families (Notor, Pleiad Nano, DTI and others), track and wallwasher variants, drivers and emergency battery sizing, lighting design calculations, freight and taxes, and any real Fagerhult price or term. The customer and the prices on this page are fictional or illustrative.

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
Variants that offer only some diameters, beams and accessoriesOnly with workarounds
Each variant has its own diameters, beams and accessories. A rules-based CPQ needs a compatibility table or one rule per variant, edited again whenever the range changes.		Variant, diameter, beam and accessories arrive in one request and are compared on every call.
Lumen package limited by diameterOnly with care
A maximum per diameter is a lookup that has to be kept beside the package list.		The limit is looked up for the chosen diameter and compared with the package on every call.
Options that exclude each other (Tunable White and CRI, IP rating and ceiling, sloping cylinder and pendant)Only with workarounds
Pairwise exclusions multiply as options are added, and each needs its own message.		Each exclusion is one rule, all evaluated together, each with its own reason.
Sensors per luminaireOnly with care
A ratio of luminaires to sensors needs a calculation rule outside the catalog.		The ratio is computed from the order and checked with everything else.
A net price that depends on options, accessories, sensors and discountOnly with care
Several price rules stack, and a stated net price has to be recomputed and compared.		The price build-up is computed on every call and compared with the net price the agent states.
Every problem returned in one answerOnly with workarounds
Rules tend to fire as the quote is saved or a step is completed, so a person 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

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 Pleiad G4 downlights: a variant and diameter, lumen package, colour rendering and temperature, and more. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model and returns a verdict, every reason and the figures it computed. The product family, variant names and main options come from public Fagerhult pages; several rules and all prices are modeled for this demonstration and are not Fagerhult's.
    2. 
      
  2. I will start with the first request by the agent.
    3. 
      
  3. The agent says. Please quote 40 Pleiad G4 Surface luminaires, 165 mm, at 3,500 lm, CRI 90, Tunable White, Tunable White control and a wide beam in white. The discount is 0 percent and the order states a net price of $8,280.00. The rest of the request is on screen.
    4. 
      
  4. Before it goes out, the agent calls the validator.
    5. 
      
  5. Blocked, with five findings, all in one answer. A diameter of 165 mm is not available for this Pleiad G4 variant; Recessed comes in 70, 125, 165 and 205 mm, Surface in 128 and 168 mm, Square Recessed and Robust Recessed in 165 and 205 mm. A lumen package of 3,500 lm is above the 3,200 lm this diameter offers. Tunable White is offered with CRI 80 only. The other two are on screen.
    6. 
      
  6. The validator returned five 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 options that exclude each other (Tunable White and CRI, IP rating and ceiling, sloping cylinder and pendant), a rules-based CPQ can do this only with workarounds.
    8. 
      
  8. Now the agent resubmits.
    9. 
      
  9. The corrected request. It changes the diameter to 168 mm, the CRI to 80, the control to DALI, the protection rating to 20 IP and the stated net price to 7,240.00. It sets the colour temperature to 4,000 K.
    10. 
      
  10. It calls the validator again.
    11. 
      
  11. This time the validator clears it.
    12. 
      
  12. All five earlier findings are cleared, and the validator's total, $7,240.00, matches the quote.
    13. 
      
  13. Five 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.
