MARTZINE JOURNAL
Ideas worth taking into the work.
Practical writing about business decisions, digital execution, technology, marketing, operations and the systems that make work easier to understand and improve.

Research, decisions and practical execution.
Each article starts with a real business question and works toward a useful next step. The aim is to make the reasoning visible, not to add more noise to an already crowded internet.

Cut List Planning and Sheet Yield: Make the Material Plan Match the Parts
A good cut list plan starts with finished parts and works backward to the sheets, boards or panels that can produce them. Yield is a layout problem as much as a quantity problem.

Board Feet, Yield and Waste: Buying Rough Lumber With Less Guesswork
