ABC Task System

Overview

The ABC Task System is a triage framework for classifying tasks by priority level. Each task is assigned one of three letter categories to guide how it should be handled within the workday.

Priority Levels

• A (Must-Do Today): Critical tasks with significant consequences if not completed. These demand immediate attention and should be tackled first.
• B (Should-Do Today): Important tasks with moderate consequences. These should be addressed after all A tasks are complete.
• C (Nice to Have): Optional tasks with minimal consequences if deferred. These provide value but can be postponed or dropped if time runs out.

How It Works

• Review your full list of tasks at the start of the day
• Assign each task an A, B, or C designation based on its urgency and impact
• Complete tasks in order: all A tasks first, then B, then C
• Optionally, further differentiate within categories using sub-numbers (A1, A2, B1, etc.)

Benefits

• Provides a simple, intuitive framework for triaging tasks
• Reduces the anxiety of facing an undifferentiated to-do list
• Helps identify tasks that can safely be deferred without negative consequences
• Easy to learn and apply without tools or software

Origin

The ABC method has been a staple of time management training for decades and is widely taught in productivity literature and courses.
