The Unchained Toolbox

You can learn a quality method in a day. Knowing when to use it takes judgment.

The Unchained Toolbox is the hands-on companion to Unchained Quality. Across twenty chapters, Muhammad Fahmy teaches the working core of the quality toolbox: what each tool does, how to use it, where it breaks, and how to choose. Every tool chapter runs the same frame: what the tool is, what it is for, a worked example, where it breaks, and exercises to make it yours. Each chapter ends with an Unchained note that ties the tool back to the judgment rules of the first book.

Inside you will work through examples and exercises on the seven basic tools, control charts, Pareto analysis, the fishbone diagram and the 5 Whys, process mapping, DMAIC, root cause analysis, CAPA, design of experiments, A3 problem solving and kaizen, value stream mapping, kanban, standard work and 5S, theory of constraints, ISO 9001, auditing, benchmarking, the Kano model, and FMEA. The final chapter is the diagnosis-first selector: start with your real problem and find the tools that fit.

The worked examples and exercise numbers are constructed for teaching and labeled as such. Where a story is real, it comes from the author's own career at sea, in oil and gas, in manufacturing and in certification auditing, and it is identified.

For quality managers, operations leaders, auditors, continuous improvement practitioners, engineers and anyone who was handed a toolbox and never properly taught the tools. Read it front to back, or arrive with a problem and enter through the selector.

Use the tool. Preserve the capability.
