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

An AI sales agent prepares a valve order from the BHEL valves range: a valve family, pressure class, body material, size and operation. Before it goes out, the agent sends it to Predictika, which checks it against the ranges printed in the BHEL valves brochure and returns a verdict and every finding at once.

Scope: 22 BHEL valve families (power plant, industry and oil and gas): pressure class or rating, body material, size, class variants, blow down orifice and actuation. See everything this validator covers

This validator models orders for the 22 valve families in the BHEL valves product range brochure it was built from, not just the scenarios shown below.

  • Family, class and size — for each family the pressure classes or ratings, body materials and size range the brochure lists, for example cast steel gate valves in classes 150, 300 and 600 from 2 to 38 inches, or high pressure gate valves in classes 900 to 3500.
  • Variants and orifice — the SPL and LTD class variants of the forged steel high pressure globe and check valves (for example 3000 SPL and 3000 LTD but not a plain 3000), and the 1/8 to 1 inch orifice of the forged blow down valve.
  • Operation and quantity — at least one valve per order; motorized, pneumatic or gear operation is listed for gate, globe and check valves, so the same request on another family goes to a person.

Any valve order that touches these rules is in scope — not only the scenarios pictured here. Not covered: prices (the brochure lists none, so this validator produces no price build-up), oilfield equipment such as wellheads and Christmas trees, the product catalogue on the Tiruchirappalli unit site (not reachable), and whether a particular combination of class, material and size inside the listed ranges is actually manufactured.

The AI sales agentBuilds the valve order from the conversation and says it is ready.

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
Class, material and size limits that differ per valve familyOnly with workarounds
Each of the 22 families lists its own pressure classes, body materials and size range, so a rules-based CPQ needs a table of limits per family, and every new family adds rows to keep in step.		The valve family is part of the model, so every limit is looked up from it on every call.
Class variants that depend on the classOnly with care
A class of 3000 is valid only with an SPL or LTD variant, and 3500 only as SPL, on two families; the combination has to be written as its own rule or it slips through.		Class and variant are checked together on every call.
Options listed for some families onlyOnly with workarounds
Orifice sizes exist only for the blow down valve and SPL or LTD variants only for two forged families; a CPQ usually leaves such fields open on every other family.		The family decides which fields may be used, whatever order the choices arrived in.
Operation that the brochure lists for some families onlyOnly with workarounds
Motorized, pneumatic and gear operation are listed for gate, globe and check valves; a rules-based CPQ must either block the same request on other families or allow it, with no way to ask a person.		Where the brochure is silent, the validator returns an approval request instead of guessing.
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 a valve order from the BHEL valves range: a valve family, pressure class, body material, and more. Before it goes out, the agent sends it to Predictika, which checks it against the ranges printed in the BHEL valves brochure and returns a verdict and every finding at once.
    2. 
      
  2. I will start with the first request by the agent.
    3. 
      
  3. The agent says. Please quote 6 cast steel gate valve, class or rating 900, A105 body, 42 inch, manual operation. It is ready to send.
    4. 
      
  4. Before it goes out, the agent calls the validator.
    5. 
      
  5. Blocked, with three findings, all in one answer. A pressure class of 900 is not offered for the cast steel gate valve; the brochure lists classes 150, 300 and 600. A105 is not a body material the brochure lists for the cast steel gate valve, such as WCB and WCC. A size of 42.0 inches is not offered for the cast steel gate valve; the brochure lists 2 to 38 inches.
    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 class, material and size limits that differ per valve family, a rules-based CPQ can do this only with workarounds.
    8. 
      
  8. Now the agent resubmits.
    9. 
      
  9. The corrected request. It changes the class or rating to 600, the body material to WCB and the size to 36 inch.
    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.
    14.
