An AI sales agent's stubble cultivator order, checked before it goes out

An AI sales agent prepares an order for an OPTIMER independent disc stubble cultivator with a model, discs, linkage, roller, seed drill and options, and states the working width and disc count. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the published leaflet rules and returns a verdict, every reason and the figures it computed.

Scope: OPTIMER independent disc stubble cultivators, 3 to 12 metres (mounted, folding and trailed): tractor power, working depth, discs, linkage, rollers, seed drills, options and stated figures. See everything this validator covers

This validator models orders for the OPTIMER range in the leaflet, not just the scenarios shown below.

  • Models — the L (510 mm discs) and XL (620 mm discs) versions of the mounted OPTIMER 300, 350 and 400, the folding 400 R, 500 R and 600 R, and the trailed 4000, 5000, 6000, 7500, 9000 and 12000, 21 models in all, each with its leaflet working width, disc count, tractor power range and working depth range.
  • Equipment — the linkage, roller and seeding implement the leaflet lists for each family, mechanical or hydraulic depth adjustment, and the options the leaflet ties to particular models: levelling board (L versions of the trailed 4000 to 7500), shredder roller, gauge wheels, Steady Control and the mass kit.
  • Stated figures — the working width and number of discs an order states are compared with the leaflet values; a tractor power or required working depth that falls outside the listed range is blocked.

Any order for these OPTIMER models that touches these rules is in scope — not only the scenarios pictured here. Not covered: prices (neither the leaflet nor KUHN's public product page lists any, they come from KUHN dealers), the intermediate harrow, seed drill selectors and hydraulic adaptation, transport dimensions and weights, the 12.5 metre model that appears only on the web page, and delivery, financing and service.

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
Tractor power window that differs for every one of 21 modelsOnly with care
A lookup per model for the minimum and maximum kW. It works, but the table must be rebuilt for every model and kept in step with the leaflet.
The model, tractor power and working depth travel in one request and each is checked against that model's leaflet range.
Rollers and seed drills that are offered for some model families and not othersOnly with workarounds
Ten family-by-option rules, each a cross-field rule between the model and the choice.
Every roller and seed drill is checked against the family on every call, whatever order the choices arrive in.
Options tied to particular models, such as the levelling board on L versions of the trailed 4000 to 7500 onlyOnly with workarounds
A rule per option and per version, easy to miss when a model is added.
Each option is checked against the model on every call and the finding names the model.
Stated working width and disc count that disagree with the leafletOnly with care
A computed field is easy; comparing the figure the quote states with it is a separate validation rule someone must add.
The stated width and disc count travel with the order and are compared with the computed values.

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 tractor power of 76 kW is below the 77 kW minimum the leaflet lists for the OPTIMER L 350.
2The tractor power of 222 kW is above the 221 kW maximum the leaflet lists for the OPTIMER L 6000.
3The required working depth of 12 cm is outside the 3 to 10 cm the leaflet lists for the OPTIMER L 400.
4The required working depth of 4 cm is outside the 5 to 15 cm the leaflet lists for the OPTIMER XL 400.

Narration transcript

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 OPTIMER independent disc stubble cultivator with a model, discs, linkage, roller. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the published leaflet rules and returns a verdict, every reason and the figures it computed.
  2. I will start with the first request by the agent.
  3. The agent says. Please quote a KUHN OPTIMER XL 9000 stubble cultivator for Hollis Ridge Farms, with 620 mm discs, a tow ring. It will be pulled by a 250 kW tractor and has to work at 8 cm. The rest of the request is on screen.
  4. Before it goes out, the agent calls the validator.
  5. Blocked, with five findings, all in one answer. The tractor power of 250 kW is below the 264 kW minimum the leaflet lists for the OPTIMER XL 9000. The quote states a working width of 1200 cm, but the leaflet lists 900 cm for the OPTIMER XL 9000. The tow ring linkage is not among the linkages the leaflet lists for the trailed OPTIMER 9000 and 12000: ball joint, K80 or crossbar. The other two are on screen.
  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. What this shows: for tractor power window that differs for every one of 21 models, a rules-based CPQ is error-prone for this.
  8. Now the agent resubmits.
  9. The corrected request. It changes the model to OPTIMER L 9000, the discs to 510 mm, the linkage to K80, the depth adjustment to hydraulic and the stated working width to 900 cm.
  10. It calls the validator again.
  11. Still blocked, with one finding, all in one answer. The leaflet lists the levelling board as front-end equipment for the trailed OPTIMER 4000 to 7500 only, not for the OPTIMER L 9000.
  12. Four findings cleared; still blocked on levelling board not listed for this model.
  13. The agent resubmits once more.
  14. The revised request. It changes the levelling board to no.
  15. It calls the validator once more.
  16. This time the validator clears it.
  17. The earlier finding is cleared, and the validator's figure matches the quote.
  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.
