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

An AI sales agent prepares a quote for manual wheelchairs: the chair class, the seat width, the patient weight, the arms and leg rests, the add-ons and the number of chairs. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the product rules and returns a verdict and every reason. This validator models no prices, so the page shows no price build-up.

Scope: McKesson Brand manual wheelchairs: standard, lightweight and bariatric dual axle chairs, seat width, patient weight against capacity, arms, leg rests, add-ons and quantity. See everything this validator covers

This validator models quotes of this kind, not just the scenarios shown below.

  • Chair class and seat width — standard, lightweight and bariatric chairs, each offered in its own seat widths, with the widest bariatric seat treated as a special order.
  • Weight capacity — the patient weight against the capacity of the chair, with a clinician check when the weight comes within 10 percent of it.
  • Options and quantity — elevating leg rests that need desk length arms and are not offered on the smallest seat, the oxygen tank holder that is not offered on the standard chair, anti-tippers on bariatric chairs, and bulk orders that need contract terms confirmed.

Any chair quote that touches these rules is in scope — not only the scenarios pictured here. The product classes and option names follow public McKesson information; the seat widths, weight capacities, option compatibility and the review thresholds are modeled from comparable wheelchairs and not published by McKesson. No prices are modeled. Not covered: powered chairs, other McKesson product lines and 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
Seat widths that differ by chair classOnly with workarounds
Standard and lightweight chairs come in 16, 18 and 20 inch seats and bariatric chairs in 22, 24 and 26 inch seats, so a width is valid only for some classes.		The class and the seat width are checked together on every call.
A weight capacity that depends on class and widthOnly with care
The capacity changes with the class and, for bariatric chairs, with the seat width, and a weight close to the capacity needs a person to confirm.		The capacity is worked out on every call and compared with the patient weight, and weights within 10 percent of it are flagged for a clinician.
Options that depend on each otherOnly with workarounds
Elevating leg rests need desk length arms and a seat wider than 16 inches, the oxygen holder is closed to the standard chair, and bariatric chairs are quoted with anti-tippers.		Every dependency is evaluated on every call, whatever order the options were chosen in.
Bulk and special-order approvalsOnly with care
A 26 inch seat and an order of 25 chairs or more each go to a person to confirm stock, lead time or contract terms.		Each approval is raised on every call and listed with the others.
Every problem returned in one answerOnly with care
Rules tend to fire as a step is saved or 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 a quote for manual wheelchairs: the chair class, the seat width, the patient weight, and more. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the product rules and returns a verdict and every reason. This validator models no prices, so the page shows no price build-up.
    2. 
      
  2. I will start with the first request by the agent.
    3. 
      
  3. The agent says. Please quote 4 standard wheelchairs with a 16 inch seat, full length arms and elevating leg rests, plus an oxygen tank holder, for a patient weighing 280 lbs. It is ready to send.
    4. 
      
  4. Before it goes out, the agent calls the validator.
    5. 
      
  5. Blocked, with four findings, all in one answer. A patient weight of 280 lb is above the 250 lb capacity of this chair. Elevating leg rests are offered only with desk length arms. Elevating leg rests are not offered on a 16 in seat. The other one is on screen.
    6. 
      
  6. The validator returned four 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 seat widths that differ by chair class, a rules-based CPQ can do this only with workarounds.
    8. 
      
  8. Now the agent resubmits.
    9. 
      
  9. The corrected request. It changes the chair class to bariatric, the seat width to 22 in, the arms to desk length and the add-ons to anti-tippers, an oxygen tank holder.
    10. 
      
  10. It calls the validator again.
    11. 
      
  11. This time the validator clears it.
    12. 
      
  12. All four earlier findings are cleared.
    13. 
      
  13. Four 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.
