Predictika · Dental sterilizer orders

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

An AI sales agent prepares an order for a dental steam sterilizer for a practice, with a model, a sterilization cycle, a load, the longest instrument and the practice mains supply. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the product page rules and returns a verdict, every reason and the figures it computed.

Scope: W&H Lisa 17 and Lisa 22 dental steam sterilizers: load limits, usable chamber space, cycle time and mains supply. See everything this validator covers

This validator models orders for the two Lisa sterilizer sizes on the public W&H dental product page, not just the scenarios shown below.

  • Load limits — the maximum solid load (4.5 kg on the Lisa 17, 6 kg on the Lisa 22), porous load (1.5 kg and 2 kg) and container load (9 kg on both) against the load the practice plans to run.
  • Chamber space — the longest item against the usable chamber depth (312 mm on the Lisa 17, 400 mm on the Lisa 22) and the item width and height against 195 mm.
  • Supply and cycle time — a mains supply of 200 to 240 V AC at 50 or 60 Hz, and a cycle time stated on the order compared with the datasheet range for the selected model and cycle (B-Universal 134, B-Prion 134, B-Universal 121 or Fast Cycle).

Any order for these two sterilizers that touches these rules is in scope — not only the scenarios pictured here. Not covered: prices (W&H publishes no list prices on its product page, so this validator produces no price build-up or line-item quote), handpieces, treatment units and other W&H products, the Lisa Mini and the medical-line Lisa, accessories and their compatibility, and dealer terms.

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
A load limit that differs by model and by load typeOnly with care
Each model has its own solid, porous and container limit, so each needs its own rule, and a new model adds more rules to maintain.		The model, the load type and the load are in one request and compared on every call.
A chamber depth that depends on the modelOnly with workarounds
The longest item must be compared with a value that depends on a different choice, so it takes a lookup that must be kept in step with the product page.		The model and the item length are in one request and the limit is worked out and compared on every call.
A stated cycle time that must sit in a range set by model and cycleOnly with workarounds
The range depends on two other choices, and the figure the agent states is free text or a separate field, so it takes an extra rule for every combination.		The stated figure is part of the request and is compared with the range for the chosen model and cycle on every call.
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.

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 a dental steam sterilizer for a practice, with a model, a sterilization cycle. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the product page rules 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 W&H Lisa 22 sterilizer for a porous load of 2,500 g on the B-Universal 121 cycle, with a longest item of 420 mm and a cross-section of 200 mm. The quote states a cycle time of 75 minutes. The rest of the request is on screen.
    4. 
      
  4. Before it goes out, the agent calls the validator.
    5. 
      
  5. Blocked, with five findings, all in one answer. The load of 2,500 g is above the 2,000 g maximum for this model and load type. The longest item is 420 mm; the usable chamber space of the selected model is 400 mm deep. The item cross-section of 200 mm is above the 195 mm usable chamber width and height. 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 a stated cycle time that must sit in a range set by model and cycle, a rules-based CPQ can do this only with workarounds.
    8. 
      
  8. Now the agent resubmits.
    9. 
      
  9. The corrected request. It changes the load to 2,000 g, the longest item to 400 mm and the stated cycle time as to 70 minutes.
    10. 
      
  10. It calls the validator again.
    11. 
      
  11. Still blocked, with two findings, all in one answer. The item cross-section of 200 mm is above the 195 mm usable chamber width and height. The mains supply of 110 V is outside the 200 to 240 V AC range.
    12. 
      
  12. Three findings cleared. Still blocking: item too wide or tall for the chamber and mains voltage outside 200 to 240 V.
    13. 
      
  13. The agent resubmits once more.
    14. 
      
  14. The revised request. It changes the item width and height to 190 mm and the mains supply to 230 V.
    15. 
      
  15. It calls the validator once more.
    16. 
      
  16. This time the validator clears it.
    17. 
      
  17. Both earlier findings are cleared, and the validator's figure matches the quote.
    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.
