Direct Measurement
Direct measurement is a methodology in software development and data analysis that involves collecting data directly from a system or process without inference or estimation. It focuses on obtaining precise, objective metrics through tools like logs, sensors, or monitoring systems to assess performance, behavior, or outcomes. This approach is essential for empirical validation, debugging, and optimization in technical environments.
Developers should use direct measurement when they need accurate, real-time insights into system performance, such as monitoring application latency, tracking user interactions, or validating code efficiency. It is crucial for performance tuning, quality assurance, and data-driven decision-making, as it reduces reliance on assumptions and provides actionable evidence for improvements.
