Do I need a paid ChatGPT, Claude or Gemini plan to use this?

You need a plan that supports project-level file uploads or a persistent custom instructions area, which is available on the standard paid tiers of ChatGPT, Claude and Gemini. The guide itself works with whichever of the three you already use.

Which guide should I start with?

Start with The First Principles Factory - it's free and sets up the method the other five guides build on. From there, pick the guide that matches your most pressing problem: ERP, Lean, Manufacturing Engineering, Supply Chain and Inventory, or Quality.

Guides & AI Decision Tools

Guides Built to Be Argued With, Not Just Read.

Q: What does "upload into your AI" actually mean?

Each guide is written so you can load the PDF into a ChatGPT, Claude or Gemini project. Once it's loaded, your AI uses the guide's method and examples to question your specific situation - testing readiness, challenging assumptions and pushing back on shortcuts - instead of giving you generic advice.

Five practical guides on ERP, Lean, Manufacturing Engineering, Supply Chain and Quality - each written from fifteen years on real factory floors, and each built to be loaded into your AI as a decision tool. Start with the free guide, or go straight to the problem you're facing.

How These Guides Work

Not Just a PDF.
An AI You Can Argue With.

Every guide below is written twice over - once as a book you read, and once as a set of rules an AI can apply. Upload the PDF into a ChatGPT, Claude or Gemini project and it stops being a document. It becomes a specialist that knows the method and won't let you skip the hard parts.

Upload Once, Get a Specialist

Load the PDF into a project in ChatGPT, Claude or Gemini and every conversation afterwards draws on the guide's method and real examples - not generic advice pulled from the open internet.

Built to Disagree With You

Each guide is written to push back - testing whether your process is actually ready, demanding numbers instead of estimates, and refusing to let you automate or spend your way past a problem that hasn't been fixed.

Works With What You Already Use

No new software, no login. If you already have a paid ChatGPT, Claude or Gemini plan, you have everything you need to turn any of these guides into a working adviser this afternoon.

The First Principles
Factory

Most manufacturers are losing output and money to problems they cannot see, because they are too close to the operation to spot them. This free guide gives you the method to find them: strip any manufacturing problem back to physics, cost and constraint, then rebuild it.

Every chapter is explained in plain language with a real example behind it - including a £700,000 cost reduction, an assembly line tripled from one module a day to three, and £272,000 a year found inside a few seconds of cycle time. Every chapter ends with questions you can ask on your own floor this week.

Loaded into ChatGPT, Claude or Gemini, this guide becomes a first-principles manufacturing tool. It challenges your assumptions instead of agreeing with them, refuses to accept a number you can't derive, and pushes you to fix the process before buying a system. A focused second opinion on your real decisions, available any time.

ERP & MRP Implementation

ERP Without the Disaster

Most manufacturers have heard the horror stories: the two-year project that never delivered, the system nobody uses properly, where the real planning still happens in a spreadsheet.

The software is rarely the cause. This guide shows what actually decides whether a manufacturing system earns its money - from fixing the operation before you buy, to writing requirements before demonstrations, to choosing the partner as carefully as the software.

Loaded into your AI, this guide becomes an implementation adviser. It tests whether your process is ready before discussing software, challenges vendor claims, and refuses to let you automate a broken workflow.

What's inside - 12 chapters

What ERP and MRP Actually Do
Why Implementations Disappoint
Fix the Operation Before You Buy
Writing Requirements Before Demonstrations
Choosing the Partner as Carefully as the Software
The Four Data Foundations

Lean Manufacturing

Lean That Actually Sticks

Most manufacturers have tried lean. Many describe it as something that did not work for them - yet the tools have been proven across decades, so when a programme fails, the cause is somewhere else.

This guide covers both: the tools that genuinely move output, and the six reasons improvement programmes quietly die. Real examples throughout, including a 12% productivity improvement delivered with no new equipment, a product travelling 400 metres through a 60 metre building, and an assembly line taken from one module a day to three.

Loaded into your AI, this guide becomes a lean decision tool. It separates value from waste, insists you observe before deciding, and refuses to accept an improvement plan that starts with buying something.

Manufacturing Engineering

Manufacturing Engineering That Pays

Most factories do not need more machines. They need the ones they own to stop waiting.

This guide shows you how to find the seconds, the stations and the steps quietly costing you output, then design them out for good - covering cycle time, takt time, bottlenecks, line balancing, SMED changeover reduction, jigs and fixtures, and automation readiness. Real numbers throughout, including £272,000 a year found inside a few seconds of cycle time at half a million parts a week.

Loaded into your AI, this guide becomes a manufacturing engineering decision tool. It hunts for your constraint, demands measured cycle times rather than estimates, and refuses to let you buy capacity you already own.

What's inside - 12 chapters

Takt Time
Finding the Bottleneck
Line Balancing

Supply Chain & Inventory

Supply Chain and Inventory That Pays

Most manufacturers are sitting on cash they cannot see. On one site, £197,000 of a £984,000 stock holding was dead, with write-offs of £20,000 to £30,000 every quarter that nobody tracked as a single number.

This guide shows you how to find yours, release it, and stop the shortages that stop your line - covering dead stock, stock accuracy, ABC analysis, lead time reduction, safety stock, reorder points, supplier performance, and why MRP disappoints.

Loaded into your AI, this guide becomes a supply chain decision tool. It converts your stock into cash figures, hunts the dead lines nobody has looked at, and refuses to let you carry safety stock that's really covering an unfixed problem.

Quality Engineering

Quality Engineering That Pays

Most quality problems are not quality problems. They are process problems that nobody traced back to the source.

This guide shows you how to build quality into manufacturing so failure becomes hard, catch what escapes before it reaches the customer, and stop paying for the same mistake twice - covering cost of quality, Right First Time, FMEA, error proofing, root cause analysis, SPC, and ISO 9001. Includes how one manufacturer lifted Right First Time from 70% to 99.8% and recovered around £700,000.

Loaded into your AI, this guide becomes a quality engineering decision tool. It interrogates your defect data, hunts the root cause instead of the symptom, pushes prevention over inspection, and refuses to accept a quality claim you can't back with a number.

What's inside - 12 chapters

Cost of Quality
Right First Time
FMEA
Error Proofing

Statistical Process Control
