What is Half-Life of Skills?
Definition
The half-life of skills is the amount of time it takes for a skill to lose half its value or relevance in the marketplace due to technological or business change. For example, if a skill has a five-year half-life, a competency at year five is worth half what it was at year zero. This concept underscores the urgency of continuous upskilling.

This accelerating depreciation means organizations and individuals cannot rely on knowledge acquired years ago. Training budgets and learning culture become competitive necessities. Individuals who embrace continuous learning maintain marketability; those who do not risk rapid obsolescence.
