Every single minute...
probably several ten or even hundred thounsands of HR decisions are being made in companies, enterprises, and institutions all around the world.
Regardless who has to make all these decisions, whether an organisation's HR department as an internal service provider, or a contracted service provider external to the organisation in need of making a specific HR decision, both have at least one thing in common:
They have to accomplish an occupational assessment preceding the decision, in order to enable it being made at all.
And, the more appropriate the preceding occupational assessment process is, the more appropriate and the less inaccurate the consecutive HR decision based on it will be for the organisation, teams, or individuals involved into it.
