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

An AI sales agent prepares an order for an EEG amplifier and NeuroWorks software from public product pages, with the channels, DC inputs, sampling rate and software version a study needs. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the published specifications and returns a verdict, every reason and the figures it computed.

Scope: Natus NeuroWorks EEG amplifiers (Quantum LTM, EMU40EX, Brain Monitor): application, channels, DC inputs, sampling rate and NeuroWorks version. See everything this validator covers

This validator models orders for three Natus EEG amplifiers used with NeuroWorks software, based on the public Natus product pages, not just the scenarios shown below.

  • Amplifiers — Natus Quantum LTM (up to 256 channels, 16 DC inputs, sampling up to 16 kHz), Natus EMU40EX wireless LTM (40 channels, 4 DC inputs, up to 1,024 Hz) and Natus Brain Monitor (up to 64 channels, up to 16 DC inputs, up to 4 kHz).
  • Application — the NeuroWorks page lists the Brain Monitor for routine EEG, the Quantum, EMU40EX and Brain Monitor for long-term monitoring, and the Brain Monitor and EMU40EX for ICU; an amplifier not listed for the application is rejected.
  • Software — the Quantum and Brain Monitor need NeuroWorks 9 or newer, autoSCORE is available exclusively with NeuroWorks 10, and a stated channel capacity is compared with the product pages; Natus says availability varies by country, so an unconfirmed ship-to country needs a person to confirm.

Any order for these amplifiers that touches these rules is in scope — not only the scenarios pictured here. Not covered: prices (none are published, so this validator produces no price build-up or line-item quote), the rest of the Natus range (sleep, newborn care, EMG), accessories, service and licences.

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
An amplifier that does not support the study's channel count or sampling rateOnly with care
Each amplifier has its own channel, DC and sampling limits, so each limit becomes a separate rule per model that must be kept in step with the product pages.		The study requirements and the amplifier are in one request and compared with every limit on every call.
An amplifier listed for one application but not anotherOnly with care
Which amplifier suits routine EEG, long-term monitoring or ICU is a compatibility table, usually maintained by hand per product.		The amplifier and the application are checked together against the published list on every call.
A software option that needs a newer NeuroWorks versionOnly with workarounds
The option (autoSCORE) and the amplifier each depend on a software version, so the rules span several products and versions and break quietly when one changes.		The version is part of the request and is compared with each requirement on every call.
A stated capacity that disagrees with the product pageOnly with workarounds
The figure the agent states is free text or a separate field, so it takes an extra rule that compares it with the amplifier's own capacity.		The stated figure is part of the request and is compared with the published capacity on every call.

  

  

    
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.

    
1The study needs 257 EEG channels; the selected amplifier offers at most 256 (Quantum 256, EMU40EX 40, Brain Monitor 64).
2The study needs a sampling rate of 16,001 Hz; the selected amplifier samples at up to 16,000 Hz (Quantum 16 kHz, EMU40EX 1,024 Hz, Brain Monitor 4 kHz).
3The study needs 17 DC inputs; the selected amplifier offers at most 16 (Quantum 16, EMU40EX 4, Brain Monitor 16).
4The quote has NeuroWorks version 8; the selected amplifier requires NeuroWorks 9 or newer.
5The NeuroWorks page does not list the selected amplifier for the selected application (routine EEG: Brain Monitor; long-term monitoring: Quantum, EMU40EX, Brain Monitor; ICU: Brain Monitor, EMU40EX).
6The study needs 41 EEG channels; the selected amplifier offers at most 40 (Quantum 256, EMU40EX 40, Brain Monitor 64).
7The study needs 5 DC inputs; the selected amplifier offers at most 4 (Quantum 16, EMU40EX 4, Brain Monitor 16).
8The study needs a sampling rate of 2,048 Hz; the selected amplifier samples at up to 1,024 Hz (Quantum 16 kHz, EMU40EX 1,024 Hz, Brain Monitor 4 kHz).

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 EEG amplifier and NeuroWorks software from public product pages, with the channels. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the published specifications 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 a Natus Brain Monitor EEG amplifier for routine EEG, with 40 EEG channels and 4 DC inputs sampled at 1,000 Hz, on NeuroWorks version 8 with autoSCORE. The quote states a maximum of 64 channels for this amplifier. The rest of the request is on screen.
    4. 
      
  4. Before it goes out, the agent calls the validator.
    5. 
      
  5. Blocked, with two findings, all in one answer. The quote has NeuroWorks version 8; the selected amplifier requires NeuroWorks 9 or newer. The autoSCORE option is quoted with NeuroWorks version 8; Natus says autoSCORE is available exclusively with NeuroWorks 10.
    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 a software option that needs a newer NeuroWorks version, a rules-based CPQ can do this only with workarounds.
    8. 
      
  8. Now the agent resubmits.
    9. 
      
  9. The corrected request. It changes the NeuroWorks version to 9.
    10. 
      
  10. It calls the validator again.
    11. 
      
  11. Still blocked, with one finding, all in one answer. The autoSCORE option is quoted with NeuroWorks version 9; Natus says autoSCORE is available exclusively with NeuroWorks 10.
    12. 
      
  12. One finding cleared. Still blocking: autoSCORE needs NeuroWorks 10.
    13. 
      
  13. The agent resubmits once more.
    14. 
      
  14. The revised request. It changes the NeuroWorks version to 10.
    15. 
      
  15. It calls the validator once more.
    16. 
      
  16. This time the validator clears it.
    17. 
      
  17. The earlier finding is cleared.
    18. 
      
  18. Two problems caught in one call, fixed in two passes, 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.
