Rule Of Thumb Estimates
Rule of thumb estimates are quick, approximate calculations or judgments based on practical experience rather than precise measurements. They provide rough, ballpark figures for planning, decision-making, or initial assessments in software development and project management. This technique is often used when detailed analysis is impractical or unnecessary, offering a rapid way to gauge effort, cost, or time.
Developers should use rule of thumb estimates during early project phases, such as brainstorming or feasibility studies, to quickly assess scope and resource needs without investing excessive time. They are valuable for back-of-the-envelope calculations, prioritization, and setting realistic expectations when exact data is unavailable, helping to avoid analysis paralysis and accelerate initial planning.
