Predictika · Engine-powered forklift quotes

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

An AI sales agent prepares a quote for a 1 to 3.5 ton engine-powered forklift with a fuel, an engine and a few options. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the model line's published catalog table and returns a verdict, every reason and the figures it computed.

Scope: Toyota 8FG/8FD (1.0 to 3.5 ton) forklift quotes: model, engine, rated capacity, facility fit and options. See everything this validator covers

This validator models Toyota 8FG (gasoline) and 8FD (diesel) 1.0 to 3.5 ton forklift quotes, not just the scenarios shown below.

  • Models and engines — the ten model sizes (10, 15, 18, K20, 20, K25, 25, K30, 30 and J35) in gasoline and diesel; the 4Y gasoline engine, the 1DZ-II diesel engine, and the 2Z diesel engine, which the catalog lists only for the 20, 25, 30 and J35 diesel models.
  • Capacity and fit — the rated capacity of each model at its 500 mm load center is compared with the load on the quote and with the capacity the quote states; the overhead guard height and the outside turning radius are compared with the doorway and turning space on the quote; a load center beyond 500 mm is sent for approval.
  • Options — the diesel particulate filter is an option for diesel models only, and the Active Steering Synchronizer is not installed when optional dual front tires are fitted.

Any 8FG/8FD quote that touches these rules is in scope — not only the scenarios pictured here. Not covered: prices (the catalog has no price list, so this validator produces no price build-up or line-item quote), masts, forks and lift heights, attachments, other option dependencies, other Toyota forklift families (electric, 4-ton and larger, warehouse trucks) and regional availability, which the catalog says varies by market. The doorway and turning space are limits stated on the quote, not Toyota rules.

The AI sales agentBuilds the forklift 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
Engines listed only for certain models and fuelsOnly with care
A product rule per engine, fuel and model size. It works, but every new engine or model is another set of rules to maintain.		Model, fuel and engine are in one request and every combination is checked together.
A stated capacity that must match the modelOnly with care
A stated figure is a free-entry field; a rule can compare it with the model's rated capacity, but someone has to write and maintain that comparison for each size.		The stated figure travels with the quote and is compared with the rated capacity on every call.
Truck dimensions that must fit the customer's doorway and aisleOnly with workarounds
The truck's guard height and turning radius sit on the product, the doorway and aisle on the customer line; each comparison needs its own cross-line rule that interacts with the rest.		Truck figures are computed from the model and compared with the limits on the quote on every call.
Option notes that conflict with other optionsOnly with care
Dual front tires against the steering synchronizer, particulate filter against fuel: each is a rule between two lines that must be kept in step with the options list.		Options and requirements travel together and every conflict is checked on every call.
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

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 catalog lists the 4Y engine with the gasoline 8FG models, the 1DZ-II engine with every diesel 8FD model and the 2Z engine only with the diesel 8FD20, 8FD25, 8FD30 and 8FDJ35; the selected engine is not listed for the selected model and fuel.
2The quote needs to lift 1,001 kg, but the selected model is rated for 1,000 kg.
3The quote states a rated capacity of 3,000 kg, but the catalog gives 2,500 kg for the selected model.
4The quote states a rated capacity of 2,500 kg, but the catalog gives 2,000 kg for the selected model.
5The rated capacity applies at a 500 mm load center, but the quote has a 501 mm load center; the catalog gives no capacity for it, so a person should confirm the capacity.
6The quote needs to lift 2,600 kg, but the selected model is rated for 2,500 kg.
7The rated capacity applies at a 500 mm load center, but the quote has a 600 mm load center; the catalog gives no capacity for it, so a person should confirm the capacity.
8The selected model has an overhead guard height of 2,110 mm, which is taller than the 2,109 mm doorway clearance on the quote.
9The selected model has an overhead guard height of 2,170 mm, which is taller than the 2,150 mm doorway clearance on the quote.
10The selected model has an outside turning radius of 2,280 mm, which is larger than the 2,279 mm available on the quote.
11The selected model has an outside turning radius of 2,430 mm, which is larger than the 2,400 mm available on the quote.
12The diesel particulate filter (DPF-II) is an option for the diesel 8FD models; it is not available on a gasoline 8FG model.
13The Active Steering Synchronizer is not installed when the forklift is equipped with optional dual front tires, but the quote requires it.

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 1 to 3.5 ton engine-powered forklift with a fuel, an engine and a few options. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the model line's published catalog table 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 Toyota 8FG25 forklift with the 2Z diesel engine to lift 2,800 kg on a 500 mm load center. It has to pass a 2,200 mm doorway and turn within 2,500 mm. The rest of the request is on screen. The quote states a rated capacity of 2,800 kg.
    4. 
      
  4. Before it goes out, the agent calls the validator.
    5. 
      
  5. Blocked, with three findings, all in one answer. The catalog lists the 4Y engine with the gasoline 8FG models, the 1DZ-II engine with every diesel 8FD model and the 2Z engine only with the diesel 8FD20, 8FD25, 8FD30 and 8FDJ35; the selected engine is not listed for the selected model and fuel. The quote needs to lift 2,800 kg, but the selected model is rated for 2,500 kg. The quote states a rated capacity of 2,800 kg, but the catalog gives 2,500 kg for the selected model.
    6. 
      
  6. The validator returned three 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 engines listed only for certain models and fuels, a rules-based CPQ is error-prone for this.
    8. 
      
  8. Now the agent resubmits.
    9. 
      
  9. The corrected request. It changes the model to 8FD30 and the stated rated capacity to 3,000 kg.
    10. 
      
  10. It calls the validator again.
    11. 
      
  11. This time the validator clears it.
    12. 
      
  12. All three earlier findings are cleared, and the validator's figure matches the quote.
    13. 
      
  13. Three 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.
