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

An AI sales agent prepares a consumer mobile plan quote of the kind a carrier sends: an eximo, irumo or ahamo plan with a device, discounts and options, in Japanese yen. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the plan rules, compares the monthly total the quote states with the computed one, and returns every finding together with the line-item quote. This is an illustrative model built from public plan information; it is not NTT docomo's internal rule set.

Scope: consumer mobile plan quotes for NTT docomo's eximo, irumo and ahamo plans, with devices, discounts and options, priced in yen. See everything this validator covers

This validator models one product line: consumer mobile plan quotes for eximo, irumo and ahamo, including the device, the discounts and the options on the same quote. It handles any quote that combines these plan, discount and device choices, not only the scenarios shown on this page. It does not cover docomo's business lines, IoT or machine-to-machine contracts, or other carriers' plans.

  • Covered: plan fit — the data cap of each plan tier, the ahamo Oomori option, and call-option eligibility and redundancy.
  • Covered: eligibility — holder age, the online-only channel for ahamo, and the family group limit.
  • Covered: discounts and pricing — fiber, home 5G, electricity and d Card discounts with their eligibility and stacking rules, and the line-item monthly total.
  • Covered: devices — the Kaedoki return program's device eligibility, 24-installment payments, and credit screening above a price threshold.
  • Covered: stated total and release — the monthly total the agent states against the computed total, and the release step, which is accepted only for an allowed quote or an approved one.
  • Not covered — business, IoT and other carriers' plans, promotions and campaigns, and real docomo price schedules. Other areas can be added.
  • Labeled as assumptions — every price, discount, fee, data cap and rule on this page is an illustrative estimate based on public plan structure, not docomo's data.

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 typical CPQ products) 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
ahamo is online only and already includes 5-minute callsOnly with care
Both are product facts, but each depends on other choices on the same quote (channel, call option), so each combination needs its own rule or a reviewer.		Channel, plan and call option are checked together on every call, and each finding says what to change.
Return program limited to eligible devices, with different payment countsOnly with care
Eligibility is a property of the device, and the monthly amount changes with the program (23 payments with a residual waived, against 24 installments).		Eligibility and the monthly device amount are computed together, and the line-item quote reconciles to the total.
Set discounts that depend on the plan and cannot be combinedOnly with workarounds
The fiber and home 5G discounts differ by plan, are absent on some, and exclude each other. Rules-based CPQ usually handles this with custom code or manual review.		Each discount is looked up per plan and the stacking rule is checked on every call, with the discount shown as its own line.
Credit screening above a device price on installmentsEasy
A price threshold on one line is a standard approval rule.		The same check runs on every call, and the finding names the device and price that triggered it.
Stated total that must match the computed totalOnly with workarounds
A validation rule can compare a stated figure with a calculated one only if the stated figure is a field on the quote, which it rarely is.		The total the agent states travels with the quote and is compared with the computed total on every call.

  

  

    
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.

    
1ahamo already includes 5-minute calls, so that option is blocked as redundant
2A device above ¥120,000 on installments needs credit screening (approval)
3Expected data use must fit the plan cap (irumo tiers, ahamo 30 GB, plus 80 GB with Oomori)
4The Kaedoki return program is limited to eligible devices
5A family group is limited to 20 lines
6Any contract holder must be 18 or older
7The Oomori extra 80 GB option is available only on ahamo
8The Hikari fiber and home 5G set discounts cannot both apply
9The monthly total the agent states must match the validator's computed total
10An ahamo contract holder must be 20 or older
11ahamo is sold online only; a docomo shop cannot take the application
12Prices, discounts and fees are computed per plan: eximo usage steps, family, set, electricity and d Card discounts, options, device installments and the shop fee
