The road from TKO to SOP.

A practical milestone model for turning product definition into a stable production system — with tooling, trials, validation, PPAP and launch readiness connected.

MILESTONE LOGIC

Build maturity step by step.

01 · TKO

Tooling Kick-Off

Freeze the industrial assumptions, supplier feasibility, tooling scope, timing, risks and inputs required to start.

02 · TOOLING

Design & Build

Progress tool design, manufacturing, try-outs and modifications against product and process requirements.

03 · FOT / OFF-TOOL

First Production Evidence

Use representative tools/process conditions to expose geometry, material, process and quality gaps early.

04 · PV / VALIDATION

Prove the System

Run dimensional, functional, material and process validation; correlate simulation and physical results.

05 · PPAP

Evidence & Approval

Assemble the evidence package, close non-conformities and obtain the required approval status.

06 · BUILD MATURITY

Vehicle / Plant Builds

Check integration, assembly sequence, ergonomics, quality loops, logistics and real line behavior.

07 · LRM / LAUNCH

Readiness Decision

Confirm that critical risks are closed or controlled before the authorization of sellable production.

08 · SOP

Start of Production

Launch with controlled configuration, capacity, quality reaction plans and a ramp-up feedback loop.

PROJECT CONTROL

What belongs in the industrialization plan?

Product maturity

Design freeze, technical specifications, interface maturity, change status and validation plan.

Process maturity

Process flow, tooling, workstations, controls, FMEA/control plan, cycle time and capacity.

Supplier maturity

Feasibility, tooling progress, samples, validation, PPAP, packaging and escalation actions.

Plant maturity

Equipment, operators, logistics, quality loops, capacity demonstration and build feedback.

Issue closure

Prioritize issues by launch impact, define containment and permanent corrective action, verify effectiveness.

Change control

Link every significant change to affected parts, tools, validation, stock, documents and application date.

PRACTICAL EXAMPLE

A tooling issue is not just a tooling issue.

A dimensional deviation can propagate through tolerance chains, assembly interfaces, vehicle geometry, validation results, PPAP and SOP risk. The industrialization engineer therefore connects the technical root cause to the project milestone and the decision path.
