Production tier calculator

Model v0.1

Five questions about a product map it to a production tier. The result is encoded in the page address — copy the link and the exact scenario travels with it. The model is a draft, published to be challenged.

Batch size per production run

Recurrence

Product stability

Quality and traceability requirements

Portability

Record scenario in the addressComputation needs JavaScript, which is disabled here. Submitting still encodes your scenario into the page address — share that link and the result appears for anyone opening it with JavaScript on. The model rules are documented in full below, so the tier can also be read off by hand.

How the model works — v0.1

Each answer scores points in the order its options are listed, counting from zero: batch size 0–4, recurrence 0–3, stability 0–2, quality 0–2, portability 0–2. The scores are weighted — batch size ×1, recurrence ×1.5, stability ×2, quality ×2, portability ×3 — for a maximum total of 22.5, and the tier is 1 + (4 × total ÷ 22.5), rounded to the nearest whole number. Two floors apply on top: certified quality requires at least Tier 4, and multi-hub portability requires Tier 5. One cap applies last: a design that is still changing fast is held at Tier 2, because standardization ahead of stability is wasted work — if a floor and the cap collide, the cap wins and the tool says so.

Status

This is model v0.1 — a deliberately simple draft, published so it can be corrected in the Stage 0 expert interviews. Weights, thresholds, and missing factors (BOM structure, energy, tariffs, proximity to demand) are exactly the things to challenge. Corrections: shk@moduloa.com.
