In a world of rapid change being adaptable is paramount. Thinking about what skills are needed is only one side of the equation. 

The other consideration is which skills are durable (half-life more then 7 years) and which ones are perishable (half-life less then 2.5 years). 

Think of a tree. Durable skills form the roots and trunk of the tree. The branches create a semi-durable framework and the leaves are coming and going with the changing seasons. These are the perishable skills.

Durable skill are for example project management practices or emotionally intelligent behaviour. Communication skills or critical thinking are also durable.

Perishable skills on the other hand are often related to a specific context. For example, skills related to organisational processes, IT platforms or packages.

Skill durability may be another lens to consider when planning to invest time, energy and budget.
