Many of today's enterprises are hardly fit to play a leading role in today's world. They are designed on the past-world premises of stability and high predictability, of repetitive work with easily scalable results. They experience profound difficulties having to navigate the predominantly uncertain and unpredictable seas of today's world.
An increase in agility is needed. They adopt Scrum. But rather than updating their past-world structures while introducing Scrum, they twist Scrum to fit their current organization. An illusion of agility is created as a result.
