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

An AI sales agent prepares an order for an ELGi EN Series lubricated rotary screw air compressor for a food packaging plant: the model and working pressure, fixed or variable speed, base or tank mounting, a mounted dryer, the air the plant needs and the compressor room it will stand in. Before the order goes out, the agent sends it to Predictika, which checks it against a declarative model of what the public ELGi EN Series brochure says and returns a verdict, every reason and the figures it computed. The customer is fictional.

Scope: ELGi EN Series (60 Hz, EN 3 to EN 37) oil-lubricated rotary screw compressors only: model, pressure, drive, mounting, dryer, air delivery, noise, ambient and room. See everything this validator covers

This validator models orders for the ELGi EN Series encapsulated lubricated rotary screw air compressors, models EN 3 to EN 37 at 60 Hz, based on the public ELGi EN Series brochure, not just the scenarios shown below.

  • Model and pressure — the ten models EN 3, 4, 5, 7, 11, 15, 18, 22, 30 and 37 and the 100, 125, 150 and 175 psi g working pressures; the EN 3 is not listed at 100 psi g, and 175 psi g is on request, so it goes to a person.
  • Air delivery — the free air delivery the brochure gives for each model and pressure, compared with the air the plant needs and with the figure the order states.
  • Variable speed drive — listed for the EN 7, EN 11 and EN 15 only; its air delivery is given at 125 psi g, so other pressures go to a person.
  • Mounting and dryer — tank mounting for models up to the EN 15, a duplex arrangement (two compressors on one tank) only on a tank, and a mounted refrigerated or desiccant dryer; arrangements the brochure does not list go to a person.
  • Noise, ambient and room — the sound level against the site limit, ambient temperature up to 115 F, and for base-mounted units the footprint, height and weight against the room and floor rating.

Any order of an EN Series compressor that touches these rules is in scope — not only the scenarios pictured here. Not covered: other ELGi compressor families (oil-free, piston, portable, railway), 50 Hz models, prices (ELGi does not publish them), delivery, service plans, and filters or other accessories.

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
Air delivery that depends on several choicesOnly with care
The air a model delivers depends on the model, the working pressure and whether it is fixed or variable speed. A rules-based CPQ can store the table, but it has to be kept in step and compared with the air the plant needs.		The model, pressure and drive are read together and the brochure figure is computed on every call.
Options that exist on only some modelsOnly with care
Variable speed is listed for three of the ten models and tank mounting for models up to the EN 15. Each is a product rule per model that has to be written and maintained.		Each availability limit is checked together with the model on every call.
The figure the order statesOnly with care
The air delivery stated in the order is a free-entry field; a rule has to look up the right table row and compare.		The stated figure is a field in the request, compared with the figure for the model, pressure and drive on every call.
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.

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 an ELGi EN Series lubricated rotary screw air compressor for a food packaging plant: the model and working pressure, fixed or variable speed, base or tank mounting, and more. Before the order goes out, the agent sends it to Predictika, which checks it against a declarative model of what the public ELGi EN Series brochure says and returns a verdict, every reason and the figures it computed. The customer is fictional.
    2. 
      
  2. I will start with the first request by the agent.
    3. 
      
  3. The agent says. Please quote an ELGi EN 11, fixed speed and base mounted, at 125 psi g with no mounted dryer. The plant needs 60 cfm of air, the compressor must stay under 80 dB(A), and the ambient temperature is 95 F. The rest of the request is on screen. The quote states an air delivery of 60 cfm.
    4. 
      
  4. Before it goes out, the agent calls the validator.
    5. 
      
  5. Blocked, with two findings, all in one answer. The plant needs 60.0 cfm; this model delivers 55.0 cfm at the selected pressure. The order states 60.0 cfm; the brochure gives 55.0 cfm for this model and pressure.
    6. 
      
  6. The validator returned two 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 air delivery that depends on several choices, a rules-based CPQ is error-prone for this.
    8. 
      
  8. Now the agent resubmits.
    9. 
      
  9. The corrected request. It changes the model to EN 15 and the stated air delivery to 68.
    10. 
      
  10. It calls the validator again.
    11. 
      
  11. This time the validator clears it.
    12. 
      
  12. Both earlier findings are cleared, and the validator's figure matches the quote.
    13. 
      
  13. Two 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.
