Predictika · Compact tractor implement quotes

An AI sales agent's compact tractor and implement quote, checked before it goes out

An AI sales agent prepares a quote for a compact tractor with the implements a customer wants. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the published implement limits and returns a verdict, every reason and the figures it computed.

Scope: Kubota BX1880, BX2380 and BX2680 compact tractor quotes with mowers, cutters, tillers, blades, snow blowers, loaders, trailer loads and backhoe or non-Kubota implement requests. See everything this validator covers

This validator models implement quotes for the Kubota BX80 series tractors (BX1880, BX2380, BX2680), not just the scenarios shown below.

  • Size limits — the largest mid-mount mower, one-blade rotary cutter, rear-mount mower, rotary tiller and front blade for each tractor, and the largest snow blower, front loader and trailer load.
  • Companion parts — a front blade and a snow blower each need a sub frame on the quote.
  • Not allowed or to confirm — backhoes cannot be attached and implements not sold or approved by Kubota are blocked; forestry use goes to a person, because these tractors have no protective structures for it.

Any quote for these three tractors that touches these limits is in scope — not only the scenarios pictured here. Not covered: prices (this validator has no price build-up or line-item quote), the BX23S tractor-loader-backhoe, other Kubota series, implement weights and the other limits on Kubota's sheet, and soil or operating conditions. Assumptions: the BX2380 and BX2680 share the same limits on Kubota's sheet; the implement count is the number of mowers, cutters, tillers, blades, snow blowers and loaders with a width on the quote.

The AI sales agentBuilds the tractor and implement quote 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
Size limits that differ by tractor: mower, cutter, tiller and blade widthsOnly with care
A product rule per tractor and implement. It works, but every limit has to be kept in step with the manufacturer sheet.		Limits are looked up from the tractor and every one is checked together.
Stated implement counts that must equal what the quote actually holdsOnly with care
A stated figure is a free-entry field; a rule can compare it with a computed count, but only if the count is kept in step with every line.		The stated count travels with the quote and is compared with the computed count on every call.
A part that one implement needs: sub frames for front blades and snow blowersOnly with workarounds
The requirement depends on the implement on one line and a part on another, so it needs a cross-line rule that interacts with the others.		The implements and parts are in one request and the requirement is checked with the rest.
An implement that can never be fitted: a backhoe on these tractorsOnly with workarounds
A prohibition across the catalog is often modelled as an incompatibility between two products, and it is easy to miss when a line is added later.		The prohibition is one rule that applies to every quote.
Every problem returned in one answerOnly with workarounds
Rules tend to fire as the quote 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
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 a mid-mount mower 55 inches wide; this tractor allows at most 54 inches.
2The quote has a one-blade rotary cutter 43 inches wide; this tractor allows at most 42 inches.
3The quote has a rear-mount mower 49 inches wide; this tractor allows at most 48 inches.
4The quote has a rotary tiller 43 inches wide; this tractor allows at most 42 inches.
5The quote has a front blade 55 inches wide; this tractor allows at most 54 inches.
6A front blade needs a sub frame and the quote has none.
7The quote has a snow blower 51 inches wide; this tractor allows at most 50 inches.
8A snow blower needs a sub frame and the quote has none.
9The quote has a front loader 49 inches wide; this tractor allows at most 48 inches.
10The quote has a trailer load of 1766 pounds; this tractor allows at most 1765 pounds.
11Backhoes cannot be attached to this tractor.
12The quote includes an implement that is not sold or approved by Kubota.
13The tractor has no protective structures for forestry; Kubota limits it to transport and stationary work, so a person should confirm the use.
14The quote states 5 implements; the quoted widths give 3.

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 compact tractor with the implements a customer wants. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the published implement limits 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 Kubota BX1880 compact tractor with a 60-inch mid-mount mower, a 50-inch rotary tiller and a 48-inch front loader. The quote states 3 implements. 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 a mid-mount mower 60 inches wide; this tractor allows at most 54 inches. The quote has a rotary tiller 50 inches wide; this tractor allows at most 42 inches.
    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 size limits that differ by tractor: mower, cutter, tiller and blade widths, a rules-based CPQ is error-prone for this.
    8. 
      
  8. Now the agent resubmits.
    9. 
      
  9. The corrected request. It changes the tractor to Kubota BX2380.
    10. 
      
  10. It calls the validator again.
    11. 
      
  11. This time the validator clears it.
    12. 
      
  12. Both earlier findings are cleared, and the validator's figure matches the quote.
    13. 
      
  13. Two 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.
