At a time when skill needs are changing ever more quickly, and headlines feature looming skills gaps and obsolescence, a focus on cultivating underlying essential human capabilities can give business leaders a sustainable way of finding the talent they need.Interestingly, they differentiate between innate capabilities - ones that can be amplified, and developed capabilities - ones that can be developed through experience and practice.
Their list of capabilities include imagination, empathy, curiosity, resilience, creativity, emotional intelligence, teaming, social intelligence, sense making, critical thinking and adaptive thinking.

The article is well worth a read.
