Consultancy is an easy business model.

In companies there are people who are paid to decide things. They also have budgets. Often they are called managers. There are consequences with decisions.

Managers learned a trick: Give the money of your budgets to consultants to make the decision your company pays you for.

If the decision was a good one: The manager was the one who hired the consultants!

If the decision was a bad one: Who could blame the manager, even the top consultants of BCG/Berger/McKinsey couldn't make the right decision, he hired the best!

Either way: The manager outsourced the work he was supposed to do but still gets paid and freed himself from the consequences. Heaven!
