Spare-parts substitution review desk

An MVP, or minimum viable product, is the smallest version that your users can actually work with. It is not a cheap version of the full solution. It is a test, built to answer the questions that decide whether the rest is worth building.

1. Pick the riskiest assumption. Here: will industrial maintenance procurement teams use it to solve "alternative parts are considered without complete compatibility evidence"?
2. Build only what tests it. One team, one use case, a few core modules. People do the rest by hand for now.
3. Run a paid pilot. Agree the acceptance criteria, input limits and reviewer responsibilities before starting.
4. Measure, then decide. Track unverified attributes and engineering review time. Then expand, change course or stop, with evidence instead of opinions.

MVP scope for this solution. Costed pilot: Document comparison; engineers approve compatibility and safety. Start with one buyer organization and a bounded set of representative inputs. Implement the first two modules: extract specified attributes; compare dimensions. Support the third task through an assisted review queue: flag missing tolerances. Handle the remaining required functions manually until validated. Include input upload, source references, user correction, a reviewer approval step and export of engineer-reviewed substitution comparison. Authentication, account isolation, deletion controls and basic operational logging are included. Specialized production certification, live write integrations and broader rollout are not included unless explicitly stated.

After the MVP. After paying customers repeatedly accept engineer-reviewed substitution comparison, automate link certifications; draft supplier questions; export review matrix. Add one tested read integration, reusable customer configuration and scheduled repeat delivery. Increase supported formats or teams only when evaluation cases and reviewer capacity cover the new scope. Document comparison; engineers approve compatibility and safety.

What the build depends on. Document alignment, field provenance, unit normalization, missing-value handling and reviewer correction. Similar-looking documents may contain materially different terms. Obtain representative authorized inputs, an agreed review rubric and a buyer-side owner. Specific scope: Document comparison; engineers approve compatibility and safety.

Pricing to test

Test USD 300-1,500 for one bounded comparison package, then USD 150-600 monthly for recurring volume with review limits. Complex expert interpretation is separately priced. Figures are hypotheses. For this buyer, package the first sale around compare three candidate parts and the defined engineer-reviewed substitution comparison. Record actual review effort before offering a recurring allowance. The commercial pilot fee is distinct from the platform development budget.

Message to test

Make missing substitution evidence explicit before ordering. Demonstrate the result with compare three candidate parts for industrial maintenance procurement teams. Use a concrete before-and-after example without promising unmeasured savings.

Where to find buyers

Maintenance associations and parts distributors

Lead magnet

Compare three candidate parts

The first 30 days

1. Week 1: interview five prospective buyers from industrial maintenance procurement teams and inspect how they handle alternative parts are considered without complete compatibility evidence.
2. Week 2: prepare compare three candidate parts using authorized or synthetic material.
3. Week 3: share the demonstration through maintenance associations and parts distributors and seek one bounded paid pilot.
4. Week 4: measure unverified attributes and engineering review time, review delivery effort and ask for a repeat purchase. This is a validation schedule, not a promise that the full product can be built in thirty days.

Paid pilot

Agree the acceptance criteria, input limits and reviewer responsibilities before starting. Run compare three candidate parts and deliver engineer-reviewed substitution comparison. Compare unverified attributes and engineering review time with the buyer's current process on comparable cases; include corrections, missed issues and reviewer time. Seek payment and repeat use. Stop or revise the scope if data access, accuracy or unit economics fail.

Success metrics

Unverified attributes and engineering review time

Retention and expansion

Build repeat use around engineer-reviewed substitution comparison. Save approved configurations and review decisions with permission, revisit unresolved exceptions and show progress on unverified attributes and engineering review time. Offer a recurring volume allowance after repeat demand; expand to adjacent tasks only when the buyer asks and delivery quality remains acceptable.

Why clients would pick it

A niche comparison schema, reviewed extraction examples and clear handling of the differences that matter to a specific buyer. For this concept, accumulate permissioned examples and reviewer corrections around make missing substitution evidence explicit before ordering. The durable asset is reliable task-specific execution and trusted customer configuration, not access to a general-purpose AI model.

Alternatives and positioning

Spreadsheet comparisons, professional reviewers, document diff tools and manual quote or contract review. Position this concept around make missing substitution evidence explicit before ordering. Compare it against the customer's current process on the same representative task. This is proposed differentiation; no exhaustive competitor study or uniqueness claim has been established.

Main delivery costs

Document parsing, field alignment, source verification, expert interpretation, clarification rounds and changing document formats. Initial validation additionally budgets for engineering review. Track model usage, storage, reviewer minutes, exception handling and customer support per accepted deliverable.
