Improving work, leadership and organisations through evidence-based psychology.

A CENTRAL AREA OF PRACTICE

When the person is not the problem—
but the fit is.

Person–job fit describes the alignment between a person's abilities, needs, values and preferred ways of working—and the actual demands, resources and conditions of their role.
