What Is Volatility?
Volatility is the possibility of rapid and unpredictable change. In a volatile environment, conditions that were true yesterday may not hold today, making fixed long-range plans risky.
In Practice
Volatile markets, technologies or requirements demand short planning horizons and the ability to re-plan quickly. Teams respond with rolling-wave planning, buffers, options thinking and frequent delivery so they can adjust course before a change becomes costly. The aim is resilience, not perfect prediction.
PMBOK 8 Context
Volatility is part of the Uncertainty performance domain in the PMBOK Guide, 8th Edition, and is often cited as the “V” in VUCA (volatility, uncertainty, complexity, ambiguity). See also complexity and ambiguity.
