From job descriptions to skill portfolios: rewriting the HR contract

The job description was invented for a world where roles changed slowly. AI breaks that assumption. The half-life of a task is shrinking, while the half-life of a skill is what increasingly defines value.

The shift

From	To
Role-based hiring	Skill-based deployment
Annual reviews	Continuous skill signals
Training catalogs	Personalised learning paths

Where to start

Pick one critical job family. Map it as a portfolio of skills with proficiency levels. Then ask three questions:

• Which skills will AI augment?
• Which will AI replace?
• Which become more uniquely human?

That single exercise reframes reskilling from "training spend" into a strategic capability investment.
