Lesson Content/Board Summary
Organizational Structure
Meaning of Organizational Structure
Organizational structure is the arrangement of positions, duties, and reporting lines in an organization to show how work is coordinated and who is responsible to whom.
Types of Organizational Structure
The following are common types of organizational structure:
- Line structure: authority flows from the top to the lower levels in a straight chain of command.
- Functional structure: departments are created based on functions, and workers report to heads of their functional units.
- Line-and-staff structure: line officers have direct authority, while staff officers provide advice and specialist support.
Line Structure
Line structure is a structure where each worker receives instructions from one superior in a clear chain of command.
The following are advantages of line structure:
- simple to understand and operate.
- clear authority and responsibility.
- fast decision making because control is direct.
The following are disadvantages of line structure:
- too much work and pressure on top managers.
- limited specialist advice for decision making.
- may not suit large organizations with complex tasks.
Functional Structure
Functional structure is a structure where the organization is divided into departments based on functions such as administration, finance, production, and marketing.
The following are advantages of functional structure:
- specialization improves efficiency and quality of work.
- clear grouping of similar activities.
- better use of skilled personnel in each department.
The following are disadvantages of functional structure:
- slow decision making when many departments must agree.
- possible conflict between departments.
- workers may focus on department goals and ignore overall organizational goals.
Line-and-Staff Structure
Line-and-staff structure is a structure where line officers direct the main work while staff officers give advice and technical support.
The following are advantages of line-and-staff structure:
- expert advice improves quality of decisions.
- reduces workload on line managers through support services.
- suits medium and large organizations with complex tasks.
The following are disadvantages of line-and-staff structure:
- conflict may arise between line officers and staff officers.
- more costly because specialists and staff services are needed.
- delay may occur when advice and approval are required.

Note for teachers using this lesson plan
Use simple, clear charts and relate each structure type to familiar examples such as school administration and small businesses. Emphasize short definitions, listed types, and advantages and disadvantages to match examination requirements.
