What do staff positions contribute to a line-and-staff organization?

1. Staff positions are added to a line organization as the firm grows more complex. 2. They provide specialized advisory and support services to line managers. 3. Producing goods and services is the work of line positions, not staff positions. 4. Final authority stays with the line, and ownership is a matter of capital rather than structure. _Source: OpenStax Introduction to Business (CC BY 4.0), Ch 7 "Designing Organizational Structures", section 7.1 Line-and-Staff Organization_
