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

An AI sales agent prepares an order for FIREROD cartridge heaters: the diameter and length, the voltage and watts, the leads, an optional thermocouple, the service level, a discount and the total. Before the order goes out, the agent sends it to Predictika, which checks it against a declarative model of what fits what and returns a verdict, every reason and the total it computed.

Scope: Watlow FIREROD cartridge heaters: diameter, length, voltage, watts, watt density, leads, thermocouple, zones, service level, discount and total. See everything this validator covers

This validator models FIREROD cartridge heater orders, not just the scenarios shown below.

  • Size and voltage — the seven diameters from 1/8 to 1 inch, the lengths each diameter allows and the voltages each diameter is offered in.
  • Watts and current — the watt density must stay within the limit for the use (lower in free air than in a bore) and the current within the limit for the diameter.
  • Leads and temperatures — fiberglass, MGT, PTFE, silicone and mineral-insulated leads each have a voltage and temperature rating, and the sheath has a temperature limit.
  • Options and service — thermocouple, heat zones, low leakage, dual voltage, bending, termination and fast track service each restrict the choices.
  • Discount and total — a discount above 15 percent needs approval and the total the order states is compared with the total computed from the modeled price list.

Any FIREROD order that touches these rules is in scope — not only the scenarios pictured here. Dimensions, voltages, watt density limits, temperature ratings and lead facts follow the public FIREROD data sheet. Some limits and thresholds (for example the current limits of two diameters, the discount thresholds and the fast track restrictions) and every price are modeled from comparable cartridge heaters, not published by Watlow; all prices are illustrative.

The AI sales agentBuilds the heater order from the conversation with the customer and says it is ready.
Predictika validatorChecks every rule at once and returns the verdict, each finding, and the computed figures.

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
A watt density limit that depends on the useOnly with care
The limit is lower in free air than in a bore, so a rule must read the use, the watts, the diameter and the length together.		The watt density is computed inside the model and compared with the limit on every call.
Leads that depend on the voltageOnly with workarounds
Each lead type has its own voltage and temperature rating, so a table or one rule per lead type is needed and edited when a lead is added.		The lead, the voltage and the temperature are checked together on every call.
A fast track length limit that depends on the service levelOnly with care
Fast track service accepts only short heaters, so a rule must read the service and the length across lines.		The service and the length are fields of one request and are checked in the same pass.
A total reconciled with a stated oneOnly with workarounds
The total comes from the diameter, length, leads, thermocouple, quantity tier and discount, and a separate calculation is needed to compare it with the figure the order states.		The total is computed inside the model and compared with the stated one 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 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
Click to expand
    
Every rule is checked on every call, in any order the choices arrive; one problem never hides another. Blocking findings stop the order; approval findings need a person to sign off; everything else is computed.

    
1A sheath length of 0.75 inches is below the 7 eighths minimum for this diameter.
2480 V is offered on the 5/8 inch to 1 inch diameters; the 1/8 inch to 1/2 inch sizes are 240 V maximum.
3Fiberglass leads are rated 300 V and mineral-insulated leads 240 V; 480 V needs MGT, PTFE or silicone leads.
4The heater draws 100 tenths of an amp; this diameter allows 97 tenths.
5An internal thermocouple does not fit the 1/8 inch diameter.
6The heater runs at 513 watts per square inch; the limit for this use is 400.
7A sheath temperature of 1,401 F is above the 1,400 F limit for this sheath material.
8The lead area reaches 483 F; this lead type is rated 482 F.
94 heat zones requested; this diameter supports up to 3.
10Low electrical leakage is offered on the 3/8 inch to 3/4 inch diameters.
11Fast track service is limited to heaters of 24 inches or less; this one is 25 inches.
12Mineral-insulated leads are not part of fast track service.
13A lead length of 73 inches is outside the 1 to 72 inch range.
14Stainless hose or braid lead protection is not offered on the 1/8 inch diameter.
15This length is above the recommended maximum for the diameter (36 inches); longer lengths may be available and a person should confirm.
16A discount of 16 percent is above the 15 percent a sales agent may give.
17A discount of 51 percent is outside the 0 to 50 percent range.
18Dual voltage is a made-to-order option; engineering should confirm it.
19A bent heater with a sheath above 1,000 F needs Watlow to confirm.
20The order has 0 heaters; at least 1 is needed.

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 FIREROD cartridge heaters: the diameter and length, the voltage and watts, the leads, and more. Before the order goes out, the agent sends it to Predictika, which checks it against a declarative model of what fits what and returns a verdict, every reason and the total it computed.
    2. 
      
  2. I will start with the first request by the agent.
    3. 
      
  3. The agent says. Please order 12 FIREROD cartridge heaters, 1/4 inch diameter, 26.25 inches long, 120 volts, 300 watts, with MGT leads 18 inches long. The order states a total of 794.16 dollars. The rest of the request is on screen.
    4. 
      
  4. Before it goes out, the agent calls the validator.
    5. 
      
  5. Blocked, with one finding and two approvals, all in one answer. Fast track service is limited to heaters of 24 inches or less; this one is 26.25 inches.
    6. 
      
  6. The validator returned one blocking finding and two approvals 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 a fast track length limit that depends on the service level, a rules-based CPQ is error-prone for this.
    8. 
      
  8. Now the agent resubmits.
    9. 
      
  9. The corrected request. It changes the length to 8, the discount to 10 percent and the total stated on the order to 450.96. It removes the dual voltage.
    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 order. That is the value of Predictika's validator: catching mistakes before they reach the customer. Now you can try the other scenarios yourself.
