How to Use This Skill

• Without arguments - load the core decision frameworks below.
• With a topic - use the Topic Index to find the relevant chapter, then read that chapter file.
• With a chapter - ask for ch06 or a chapter title to load its formulas and worked example.
• For quick decisions - read cheatsheet.md; use glossary.md for terms and patterns.md for repeatable methods.

This skill synthesizes the textbook into decision rules and worked examples. It does not replace current GAAP, tax, legal, regulatory, or company-specific guidance.

Core Frameworks and Mental Models

1. Start with the decision and cost object

Define what management is deciding and what receives the cost: job, product, process, department, customer, segment, or investment. Then classify costs as direct or indirect relative to that object. Trace what is economically traceable; allocate what is not. Cost behavior and relevance are relational, not inherent labels.
