That's right...it will *lead* to more worries. Management will eventually realize that the benefits they expected are not accruing, and they'll wonder why.
Using an existing terminology could make them feel less anxious to begin with, because it would imply continuity rather than change. Genuine change is needed, however, if an organization is to implement Scrum and obtain its associated benefits. Using Scrum's own terminology emphasises the fact that it involves a different way of working, and that change may neither be comfortable nor something that can be taken for granted.
