Changes in strategy often require changes in the way an organization is structured :
•Structure largely dictates how objectives and policies will be established. The structural format for developing objectives and policies can significantly impact all other strategy-implementation activities.
•Structure dictates how resources will be allocated. Eg. Allocation of resources will be determined by whether structure is based on customer groups or along functional areas.
