Answer 1

Business Unit Level Strategy

  

A strategic business unit may be any profit center that can be planned independently from the other business units of your corporation. At the business unit level, the strategic issues are about both practical coordination of operating units and about developing and sustaining a competitive advantage for the products and services that are produced

Many companies feel that a functional organizational structure is not an efficient way to organize activities so they have reengineered according to processes or strategic business units (called SBUs). A strategic business unit is a semi-autonomous unit within an organization. It is usually responsible for its own budgeting, new product decisions, hiring decisions, and price setting. An SBU is treated as an internal profit centre by corporate headquarters. Each SBU is responsible for developing its business strategies, strategies that must be in tune with broader corporate strategies
