TPI Daily: A Simplified Three-Dimensional Decision Algorithm for Practical Task Management

A Simplified Three-Dimensional Decision Algorithm for Practical Task Management introduces a low-overhead, rule-based framework for prioritizing daily tasks using three orthogonal dimensions Impact (value), Urgency (time-sensitivity), and Duration (execution time). Unlike traditional systems such as GTD or the Eisenhower Matrix, TPI Daily operates with O(1) computational complexity per task and requires less than five minutes of daily overhead. The algorithm deterministically classifies tasks into five actionable categories: Do Now, Do Today, Deep Work, Schedule, and Delegate/Drop. The paper formalizes the decision rules, proves complete input-space coverage, and outlines daily and weekly operational protocols that reduce decision fatigue while maintaining high completion rates and cognitive focus. Key contributions include: A three-dimensional task classification model (I/U/D) A constant-time deterministic decision algorithm A complete practical workflow integrating morning and evening reviews Quantitative performance metrics for evaluating success (completion rate, deep work frequency, decision overhead) TPI Daily is designed for professionals seeking a minimal yet rigorous task management method that balances efficiency, clarity, and cognitive simplicity.
