Design of Experiments (DoE)

Design of Experiments (DoE, DOX, or experimental design) is a formal way to design a task that explains the variation under conditions.

Purpose

DoE provides a systematic approach to:

• Identify which factors influence outcomes
• Understand relationships between variables
• Optimize processes and systems
• Make data-driven decisions with controlled experiments

Key Principles

• Control: Compare experimental groups to control groups
• Randomization: Reduce bias by random assignment
• Replication: Repeat experiments to verify results
• Blocking: Account for known sources of variation

Applications

• Scientific research
• Product development and optimization
• Process improvement
• A/B testing and experimentation
• Quality control
