Fix the first question
Define the business question and success condition before implementation starts.
Process and pricing
Start with what
you verify.
Free diagnosis, fixed-scope mathematical prototype, production system development, and continuous improvement. Each phase ends with a clear artifact and decision gate.
- Start smallUse the first phase to verify the question and representative data.
- Separate costsA one-time prototype and monthly development capacity are different contract units.
- Decision gatesProceed, reframe, or stop after each phase.

Cost noteThe page explains standard models, not a binding estimate. Estimates and contracts take precedence over page text, and effect numbers or delivery dates are not guaranteed in advance.
How we reduce rework
Reduce rework before trying to reduce development cost.
For mathematical automation, the largest uncertainty is not the number of screens. It is whether the data, rules, and comparison criteria can be represented together.
Split the conditions
Separate hard constraints from preferences so the system can explain trade-offs.
Compare with the baseline
Compare against the current plan using the same metrics: time, violations, delay, or load.
Stop by phase
Each phase has a point where continuing, reframing, or stopping is acceptable.

Phases and gates
Put a decision at the end of every phase.
Each phase is described by input, activity, deliverable, and gate. The goal is to keep the next investment decision visible.
Phase 00
Free diagnosis
Clarify the target work and missing data.Recommended entry
Check the target work, frequency, current procedure, sample data, and the first measurable question.
First output
Workflow, field definitions, representative cases, and conditions for moving to prototype.

Pricing
Separate one-time validation from monthly development capacity.
The most important distinction is contract unit. A one-time prototype and a monthly development frame are not the same product, even if a number looks similar.
One-timeMathematical automation prototype

JPY 298,000
One business area and one representative dataset. Verifies feasibility before production build.

All prices are before tax. Cloud, maps, notifications, external APIs, licenses, devices, audits, travel, and special legal or security review are actual costs or separate estimates. The estimate and contract take precedence.

Cost factors
Screens are not the only reason costs change.
The checker does not issue an automatic price. It shows which areas need preparation before the estimate.

Bring the current procedure, one representative dataset, the people who decide, and the metric that tells whether the next phase is worth continuing.
Finite Field side
Finite Field side
Finite Field separates hard constraints, preferences, data gaps, and delivery capacity, then turns them into a prototype, system design, or monthly development queue.
Working model
Do not throw a specification over the wall. Run decisions together.
The page is designed to reduce unclear handoffs. The first conversation should already know what data, decision owner, and next gate are needed.

Gate: CONTINUE / CHANGE / CLOSEFAQ
Common questions about process and pricing.
The answers separate one-time validation, monthly development capacity, and contract conditions so the first discussion is not dominated by price confusion.
01Do we need a monthly contract from the start?
No. Start with the free diagnosis, then choose a fixed-scope prototype only if you need to verify feasibility before production development.
02How is the prototype different from the Light plan?
The prototype is a one-time validation package. Light is a monthly development frame for Web maintenance or small improvements. The price may look similar, but the contract unit and deliverables differ.
03Is this page a fixed estimate?
The page shows standard models and decision criteria. Formal scope, tax, payment, acceptance, cancellation, IP, and external costs are fixed by estimate and contract.
04Are server and external service costs included?
Cloud, maps, notifications, external APIs, store registration, licenses, devices, audits, and travel are handled as actual costs or separate estimates.
