Predictika · Backhoe loader driveline orders

An AI sales agent's backhoe loader driveline order, checked before it goes out

An AI sales agent prepares an order for a number of backhoe loader driveline sets: a front axle, a rear axle, a torque converter transmission, optional ECU, Direct Drive and ECOlogy modules, a differential, and the wheel mounting and loads of the machine. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the Carraro Drive Tech driveline recommendations and returns a verdict, every reason and the totals it computed.

Scope: Carraro Drive Tech backhoe loader drivelines: front and rear axles, the TCB56 2WD, TCB80, TCB80 SPS and TCB90 PS transmissions, ECU, Direct Drive and ECOlogy modules, widths, wheel mounting, steering angle and loads. See everything this validator covers

This validator models Carraro Drive Tech backhoe loader driveline orders, as described in the public Carraro backhoe loader drivelines brochure, not just the scenarios shown below.

  • Recommended driveline for the engine — for engines from 50 to 88 kW, two-wheel-steer or four-wheel-steer machines, the front axle, rear axle and transmission that the brochure recommends for that power band.
  • Electronics and modules — the ECU needed with the TCB80 SPS and TCB90 PS transmissions; the Direct Drive and ECOlogy Mode modules, which the validator allows only with those two transmissions.
  • Axle fit — dynamic load capacity, maximum steering angle, wheel mounting (8 M18x1.5 studs on 275 mm or 10 M22x1.5 on 335 mm) and the overall widths offered for each axle.
  • Order terms — the quantity, a pre-series quantity below 5 sets and an order above 2,000 sets (both go to a person), the discount (a person approves above 12 percent, blocked above 25 percent), and the stated total against the computed total.

Any Carraro backhoe loader driveline order that touches these rules is in scope — not only the scenarios pictured here. Not covered: agricultural tractor, telehandler and other Carraro axle lines. All prices are illustrative and are not Carraro list prices; the series minimum, the order-size and discount thresholds, the limited-slip option and the module compatibility are modeled from comparable suppliers and are not published by Carraro.

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 driveline that must match the engine powerOnly with care
Each power band recommends different axles and a transmission for two-wheel and four-wheel steer, so every band needs its own set of product rules, and a new band means editing all of them.		The engine power, the steering type and every part are in one request and checked together against the recommendation table on every call.
Parts that depend on each otherOnly with care
The ECU is needed with some transmissions and the modules only work with those same transmissions, so the rules must read the transmission from another line.		The transmission, the ECU and the modules are fields of the same request and are checked together.
Axle limits such as load, steering angle and wheelsOnly with care
Each axle has its own load capacity, steering angle and wheel mounting, so a lookup and a comparison rule are needed for every axle.		Each axle's limits are compared with the machine's values directly on every call.
A stated total that must match the computed totalOnly with workarounds
The total is built from several parts, a quantity and a discount, so a separate rule is needed to recompute it and compare it with the stated figure.		The stated total is a field of the request and is compared with the computed total 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.

  

  

    
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 machine engine is 45 kW; the Carraro backhoe driveline recommendations cover 50 to 88 kW.
2The machine engine is 95 kW; the Carraro backhoe driveline recommendations cover 50 to 88 kW.
3The four-wheel-steer driveline recommendations start at 71 kW; the engine is 65 kW.
4This front axle is not the recommended one for the machine steering type and engine power.
5This rear axle is not one of the recommended ones for the machine steering type and engine power.
6This transmission is not one of the recommended ones for the machine steering type and engine power.
7The TCB80 SPS and TCB90 PS transmissions are electronically controlled and need the Carraro ECU; the quote has none.
8The Direct Drive and ECOlogy Mode modules are modeled for the TCB80 SPS and TCB90 PS transmissions only.
9The front axle load is 96 kN; this front axle has a dynamic load capacity of 95 kN.
10The rear axle load is 85 kN; this rear axle has a dynamic load capacity of 80 kN.
11The machine needs a 58 degree steering angle; this front axle allows 55 degrees.
12The front wheels do not match the axle wheel mounting (the 26.16, 26.22 and 26.24 axles take 8 M18x1.5 studs on 275 mm; the 26.32 and 26.43 take 10 M22x1.5 on 335 mm).
13A front overall width of 2,000 mm is not offered for this front axle.
14A rear overall width of 1,800 mm is not offered for this rear axle.
15The order has 3 driveline sets, below the modeled series minimum of 5; a person should confirm it is a prototype order.
16The order has 2,500 driveline sets; a person should confirm capacity.
17The order gives a 18 percent discount; discounts above 12 percent need a person to approve.
18The order gives a 30 percent discount; this model allows at most 25 percent.
19The order states 62,700,100 cents in total; the components quoted add up to 62,700,000 cents.
20The order has no driveline sets.

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 number of backhoe loader driveline sets: a front axle, a rear axle, a torque converter transmission, and more. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the Carraro Drive Tech driveline recommendations 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 400 driveline sets for a four-wheel-steer backhoe loader whose engine is rated at 85 kW: the 26.32 front axle. The front wheels are 8 stud M18, the overall widths are 2105 mm front and 2105 mm rear, the machine needs a 45 degree steering angle. The rest of the request is on screen.
    4. 
      
  4. Before it goes out, the agent calls the validator.
    5. 
      
  5. Blocked, with four findings, all in one answer. This front axle is not the recommended one for the machine steering type and engine power. The TCB80 SPS and TCB90 PS transmissions are electronically controlled and need the Carraro ECU; the quote has none. The front axle load is 95 kN; this front axle has a dynamic load capacity of 90 kN. 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 a driveline that must match the engine power, a rules-based CPQ is error-prone for this.
    8. 
      
  8. Now the agent resubmits.
    9. 
      
  9. The corrected request. It changes the front axle to 26.43, the ECU on the order to yes, the front wheel mounting to 10 x M22x1.5 and the total stated on the order to $3,135,600.
    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 $3,135,600 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.
