An AI sales agent's CyberKnife system quote, checked before it goes out

An AI sales agent prepares a quote for a CyberKnife S7 or M6 system for a hospital: the collimators and the Xchange collimator changer, the couch, the tracking options and packages, the patient and target size, a discount, years of service and the total. Before the quote goes out, the agent sends it to Predictika, which checks it against a declarative model of what the system allows and returns a verdict, every reason and the totals it computed.

Scope: CyberKnife M6 and S7 systems: collimators and Xchange, couch payload, tracking compatibility, packages, discount, service and the stated total. See everything this validator covers

This validator models CyberKnife system quotes, not just the scenarios shown below.

  • Collimators and field size — Fixed and Iris collimators reach a 60 mm field and the InCise 2 MLC reaches 115 mm; more than one housing on the quote needs the Xchange Robotic Collimator Changer.
  • Couch — the standard couch supports 159 kg and the RoboCouch 227 kg, and the patient's weight is checked against the couch quoted.
  • Tracking and imaging — Synchrony works with fiducial, Xsight Lung and Xsight Spine Prone tracking, InTempo works with fiducial, 6D Skull and Xsight Spine tracking, tracking options must be on the quote, and fiducial tracking needs at least three fiducials.
  • Packages and options — the Lung, Spine Prone, Prostate, CNS and Clinical Efficiency packages contain options, and an option that is also in a quoted package is a duplicate line.
  • Discount, service and totals — a discount above 10 percent needs approval and one above 20 percent is blocked, and the total the quote states is compared with the total computed from the system, options, couch, discount and service years.

Any CyberKnife system quote that touches these rules is in scope — not only the scenarios pictured here. Not covered: the Radixact system, planning-software seats and financing. Product names, options, packages and compatibilities follow Accuray's public CyberKnife technical specifications as Predictika read them (S7 is assumed to share the M6 option compatibilities). All prices, service tiers, the discount thresholds and the duplicate-option and Xchange rules are modeled from comparable products and are illustrative, not published by Accuray.

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
Several collimator housings without XchangeOnly with care
Whether Xchange is needed depends on how many housings the quote holds across Fixed, Iris and MLC, so the rule has to count them rather than test one field.		The housings are counted inside the model and the rule is checked in the same pass as all the others.
Tracking and imaging options that must fit togetherOnly with workarounds
Synchrony and InTempo each work with some tracking methods and not others, and the tracking option itself must be on the quote or inside a package, so several fields have to be read together.		Each compatibility and each missing option is a separate finding, all returned together.
Options also contained in a quoted packageOnly with workarounds
A package contains options, so the same option can be quoted twice. Finding that needs the package contents compared with the separate lines.		The overlap is computed inside the model and reported as one finding.
Patient weight against the couch quotedOnly with care
The limit depends on which couch is on the quote, so the rule must look up the payload before it compares the weight.		The payload for the quoted couch is looked up and compared on every call.
A stated total reconciled with the computed oneOnly with workarounds
The total is built from the system, options, couch, discount and service years, and a separate calculation is needed to compare it with the figure the quote 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 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
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 quote; approval findings need a person to sign off; everything else is computed.

    
1The quote has 2 collimator housings (Fixed plus Iris and/or InCise 2 MLC); switching between them needs the Xchange Robotic Collimator Changer.
21 option(s) are quoted separately and also come with a quoted package; remove the duplicate line(s).
3The treatment plan needs Synchrony respiratory tracking and the quote has neither the Synchrony option nor a package that includes it.
4Synchrony works with fiducial, Xsight Lung, Xsight Spine Prone and 1-View lung tracking; it cannot be combined with 6D Skull or Xsight Spine tracking.
5The treatment plan needs InTempo adaptive imaging and the quote has neither the InTempo option nor the Prostate Package.
6InTempo works with fiducial, 6D Skull and Xsight Spine tracking; it cannot be combined with Xsight Lung or Xsight Spine Prone tracking.
7The plan uses Xsight Lung tracking and the quote has neither the Xsight Lung option nor the Lung Package.
8The plan uses Xsight Spine Prone tracking and the quote has neither that option nor the Spine Prone Package.
9Lung Optimized Treatment is quoted without Xsight Lung; add Xsight Lung or the Lung Package.
10The patient weighs 160 kg; the quoted couch supports 159 kg.
11The largest target field is 70 mm; the quoted collimators reach 60 mm (Fixed and Iris to 60 mm, InCise 2 MLC to 115 mm).
12A 15 percent discount is above the 10 percent a sales director can give (modeled threshold); a person should approve it.
13A 21 percent discount is above the 20 percent limit (modeled, not company-published).
14The quote states a total of $5,000,000; the validator computes $6,052,500.
15Fiducial tracking needs at least three fiducials for 6D correction; the plan has 2. A physicist should confirm the plan.

The text of the narrated walkthrough, step by step.

    
    
      
  1. Welcome to a demo of Predictika's Validator. An AI sales agent prepares a quote for a CyberKnife S7 or M6 system for a hospital: the collimators and the Xchange collimator changer, the couch, the tracking options and packages, and more. Before the quote goes out, the agent sends it to Predictika, which checks it against a declarative model of what the system allows and returns a verdict, every reason and the totals it computed.
    2. 
      
  2. I will start with the first request by the agent.
    3. 
      
  3. The agent says. Please quote a CyberKnife S7 system with the Fixed collimators and the Iris collimator. The quote includes the Lung Package and Xsight Lung. The rest of the request is on screen. The sales rep offers a discount of 25 percent and 3 years of Advanced service and the quote states a total of 5,002,500 dollars.
    4. 
      
  4. Before it goes out, the agent calls the validator.
    5. 
      
  5. Blocked, with five findings, all in one answer. The quote has 2 collimator housings (Fixed plus Iris and/or InCise 2 MLC); switching between them needs the Xchange Robotic Collimator Changer. 1 option(s) are quoted separately and also come with a quoted package; remove the duplicate line(s). The patient weighs 160 kg; the quoted couch supports 159 kg. 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 also contained in a quoted package, a rules-based CPQ can do this only with workarounds.
    8. 
      
  8. Now the agent resubmits.
    9. 
      
  9. The corrected request. It changes the xchange collimator changer to yes, the separate options to none, the couch to RoboCouch and the total stated on the quote to 5,197,500.
    10. 
      
  10. It calls the validator again.
    11. 
      
  11. Still blocked, with two findings, all in one answer. The largest target field is 70 mm; the quoted collimators reach 60 mm (Fixed and Iris to 60 mm, InCise 2 MLC to 115 mm). A 25 percent discount is above the 20 percent limit (modeled, not company-published).
    12. 
      
  12. Three findings cleared. Still blocking: target field larger than the collimator allows and discount over the limit.
    13. 
      
  13. The agent resubmits once more.
    14. 
      
  14. The revised request. It changes the collimators to Fixed collimators, Iris collimator, InCise 2 MLC, the discount to 8 percent and the total stated on the quote to 6,483,600.
    15. 
      
  15. It calls the validator once more.
    16. 
      
  16. This time the validator clears it.
    17. 
      
  17. Both earlier findings are cleared.
    18. 
      
  18. Five 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.
    19.
