Which disadvantage of the matrix structure comes from managers rather than staff?

1. Functional and product managers may hold different goals and different management styles. 2. That clash at the top of the two chains produces power struggles. 3.

Increased feelings of ownership are an advantage of the matrix, so the last option reverses it. _Source: OpenStax Introduction to Business (CC BY 4.0), Ch 7 "Designing Organizational Structures", section 7.2 Contemporary Structures_
