Predictika · New-vehicle order validation

An AI sales agent's Tata Nexon order, checked before it goes out

An AI sales agent prepares an on-road quote for a new Tata Nexon, with a trim, engine, gearbox, edition, discount, accessories, extended warranty and finance terms. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the Nexon variants and order limits and returns a verdict, every reason and the on-road total it computed.

Scope: Tata Nexon new-vehicle orders: ten trims, petrol, diesel and CNG, manual, AMT and dual-clutch gearboxes, Dark editions, dual-tone roof, discount, accessories, warranty and finance. See everything this validator covers

This validator models Tata Nexon order quotes, not just the scenarios shown below.

  • Variants — the ten Nexon trims from Smart to Fearless+ PS with petrol, diesel and CNG engines, the manual, AMT and DCA gearboxes, the Dark and Red Dark editions and the dual-tone roof, and which combinations are offered.
  • Order limits — retail orders of one or two vehicles, fleet orders of five or more, a discount limit with a manager approval band, an accessories limit, an extended warranty of up to three years, and a manager sign-off for very large fleet orders.
  • Finance and total — the down payment and loan tenure for a financed order, and the on-road total the quote states, which must match the total computed from the ex-showroom price, registration, insurance, warranty, accessories and discount.

Any Tata Nexon order quote that touches these rules is in scope — not only the scenarios pictured here. Not covered: the Nexon EV, other Tata models, and trade-in or insurance products. Trim, fuel, gearbox and edition names follow the public Nexon variant lists; the variant availability matrix, every price, tax and insurance percentage, and the discount, accessory, warranty and finance limits are modeled from comparable products and are not published by Tata Motors, so all figures are illustrative. The validator shows a computed on-road total but no line-item table.

The AI sales agentBuilds the Nexon order quote from the conversation and says it is ready.
Predictika validatorChecks every rule at once and returns the verdict, each finding, and the computed figures.

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 variant matrix of engine, gearbox, trim and editionOnly with care
Each trim allows different engine and gearbox pairs and only some editions, so a table of allowed combinations has to be built and kept up to date.		The trim, engine, gearbox and edition are in one request and checked together on every call.
A roof option that depends on trim and editionOnly with care
The dual-tone roof is allowed on some trims and never with a Dark edition, which needs rules that refer to two other choices.		The roof, trim and edition are all in the request, so the combination is checked on every call.
A discount with a block limit and an approval bandOnly with workarounds
A block above one percentage and an approval above another need separate rules that must agree with each other and with the ex-showroom price of the chosen variant.		The discount is compared with the computed ex-showroom price on every call and returns a block, an approval or nothing.
A stated on-road total that must match the computed totalOnly with workarounds
The total is built from the price, registration, insurance, warranty, accessories and discount, so a separate rule must recompute it and compare it with the stated figure.		The stated total is a field of the request and is compared with the computed on-road total 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.

The text of the narrated walkthrough, step by step.

    
    
      
  1. Welcome to a demo of Predictika's Validator. An AI sales agent prepares an on-road quote for a new Tata Nexon, with a trim, engine, gearbox, and more. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the Nexon variants and order limits and returns a verdict, every reason and the on-road total it computed.
    2. 
      
  2. I will start with the first request by the agent.
    3. 
      
  3. The agent says. Please quote a retail order for 3 Tata Nexon Smart diesel with the AMT gearbox, in the Dark edition with the dual-tone roof. It is ready to send. The rest of the request is on screen.
    4. 
      
  4. Before it goes out, the agent calls the validator.
    5. 
      
  5. Blocked, with six findings, all in one answer. A retail order is for 1 or 2 vehicles; this one has 3. Orders of 5 or more are placed as a fleet order. The Smart trim is not offered with a diesel engine. The AMT gearbox is not offered on this trim with this fuel. The other three are on screen.
    6. 
      
  6. The validator returned six 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 order are checked against each other.
    7. 
      
  7. What this shows: for a roof option that depends on trim and edition, a rules-based CPQ is error-prone for this.
    8. 
      
  8. Now the agent resubmits.
    9. 
      
  9. The corrected request. It changes the vehicles to 2, the trim to Creative+ S, the dual-tone roof to no, the discount per vehicle to 30,000 rupees and the on-road total stated on the quote to 3,357,950 rupees.
    10. 
      
  10. It calls the validator again.
    11. 
      
  11. This time the validator clears it.
    12. 
      
  12. All six earlier findings are cleared.
    13. 
      
  13. Six problems caught in one call, fixed in one pass, and a clean order. That is the value of Predictika's validator: catching mistakes before they reach the customer. Now you can try the other scenarios yourself.
    14.
