Foundations of Organization Structure Notes
Key Elements of Organizational Structure
Organizational structure is defined as the system that dictates how job tasks are formally divided, grouped, and coordinated within an organization. When designing a structure, managers must address six key elements:
Work specialization: The degree to which tasks in the organization are subdivided into separate jobs.
Departmentalization: The basis by which jobs are grouped together.
Chain of command: The continuous line of authority from the top of the organization to the lowest level.
Span of control: The number of subordinates a manager can efficiently and effectively direct.
Centralization and decentralization: The degree to which decision-making is concentrated at a single point.
Formalization: The degree to which jobs within the organization are standardized.
Work Specialization (Division of Labor)
Work specialization, or division of labor, refers to the practice of dividing tasks into separate jobs where each step is completed by a different person.
Benefits of Work Specialization
Efficiency: It makes efficient use of employee skills.
Skill Development: Repetition increases employee skills over time.
Productivity: Minimizing between-job downtime allows for higher output.
Training: Specialized training is more efficient and less costly.
Equipment: It encourages the use of specialized, high-efficiency equipment.
Theoretical Foundations: Adam Smith
In his observations of a pin factory, Adam Smith noted the power of division of labor, stating: "Men are much more likely to discover easier and readier methods of attaining any object, when the whole attention of their minds is directed towards that single object, than when it is dissipated among a great variety of things."
Evolution and "Human Diseconomies"
During the first half of the century, managers viewed work specialization as an infinite source of productivity. However, by , it became clear that it could be carried too far. Once a certain threshold is surpassed, "human diseconomies" emerge, including:
Boredom and fatigue.
Increased stress.
Poor quality of work.
Increased absenteeism.
Higher employee turnover.
Modern Perspective
Managers today view work specialization as an important mechanism but recognize it is not a source of ever-increasing productivity. While companies like McDonald’s use high specialization for efficiency, other organizations like American Express and Ford Australia have broadened job scopes to reduce work specialization and improve engagement.
Departmentalization
Jobs are grouped together based on several criteria to ensure coordinated effort. Common types of departmentalization include:
Functional: Grouping jobs by the functions performed (e.g., Finance, Engineering, Marketing). This allows for efficiencies from putting specialists together.
Product: Grouping jobs by product line. This provides clear responsibility for product performance but can lead to duplication of services.
Geographical: Grouping jobs based on territory or geography (e.g., Western Region, Southern Region). This is effective for handling regional issues.
Process: Grouping jobs on the basis of product or service flow (e.g., testing, assembly).
Customer: Grouping jobs by the type of customer and their specific needs.
Contemporary Trends in Departmentalization
Large organizations often use a combination of these forms. Current trends include an increase in customer departmentalization to monitor customer needs better, and the use of cross-functional teams. For instance, Ford’s material planning and logistics division utilizes a cross-functional team featuring specialists from finance, purchasing, engineering, and quality control alongside members from outside logistics suppliers to improve work processes.
Chain of Command
The chain of command is the continuous line of authority clarifying who reports to whom. It relies on three core concepts:
Authority: The rights inherent in a managerial position to give orders and expect them to be followed.
Responsibility: The obligation or expectation of an employee to perform assigned duties.
Unity of Command: The principle (originally from Fayol’s 14 Principles of Management) that a person should have only one boss. Reporting to multiple bosses can lead to conflicting demands.
Current View on Chain of Command
Traditional concepts of authority and unity of command are considered less relevant in modern organizations due to Information Technology (IT). Employees can now communicate with anyone across the organization without following formal channels. Furthermore, the rise of self-managed and cross-functional teams has made the traditional linear chain of command less necessary.
Span of Control
This refers to the number of employees a manager can supervise effectively. Traditionally, wider spans are seen as more efficient because they require fewer levels of management.
Narrow vs. Wide Spans
Narrow Span Drawbacks:
Expense of adding many layers of management.
Complexity in vertical communication (messages get lost or distorted).
Tight supervision that discourages employee autonomy.
Width Determinants: The width of the span is influenced by the skills of the manager, the characteristics of employees, the complexity and similarity of tasks, physical proximity of subordinates, and the strength of organizational culture.
Current Trend
The modern trend is toward wider spans of control to reduce costs, speed up decision-making, and empower employees. However, to maintain performance, companies are investing heavily in employee training so that workers can perform effectively with less direct supervision.
Centralization and Decentralization
Centralization: The degree to which decision-making is concentrated at the top levels of the organization. Top managers make all decisions.
Decentralization: The degree to which decision-making is pushed down to the managers closest to the action.
Employee Empowerment: A subset of decentralization where decision-making authority is increased for lower-level employees.
Factors Influencing the Amount of Centralization
More Centralization is favored when:
The environment is stable.
Lower-level managers lack experience in decision-making.
The company is facing a crisis or risk of failure.
Decisions are minor or when high control is needed for strategy implementation.
More Decentralization is favored when:
The environment is complex and uncertain.
Lower-level managers are capable and want a voice.
The company is geographically dispersed.
The culture is open and flexible.
Modern Trend example
Honeywell Pacific transitioned from a hierarchical structure to a flatter, team-based, decentralized model. This resulted in increased revenues and more intimate knowledge of major customer needs.
Formalization
Formalization refers to the degree to which jobs are standardized.
High Formalization: Roles are clearly defined with many rules and procedures, leaving employees with little discretion.
Low Formalization: Roles are less structured, and employees have more freedom in how they perform their work.
Common Organizational Designs
1. Simple Structure
Characterized by low departmentalization, wide spans of control, authority centralized in a single person, and little formalization.
Practiced in: Small businesses where the owner and manager are one.
Strengths: Fast, flexible, inexpensive, clear accountability.
Weaknesses: Inadequate as an organization grows; high centralization causes information overload at the top.
2. Bureaucracy
The hallmark of bureaucracy is standardization. It involves highly routine operating tasks, formalized rules, functional departmentalization, centralized authority, and narrow spans of control.
Strengths: Highly efficient at performing standardized activities; economies of scale; minimal duplication of personnel.
Weaknesses: Subunit conflicts; obsessive concern with rules; lack of discretion to handle unique problems.
3. Matrix Structure
The matrix configuration combines functional and product departmentalization, creating dual lines of authority.
Practiced in: Aerospace, R&D labs, construction, hospitals, and consulting firms.
Strength: Facilitates coordination of complex and interdependent activities; efficient allocation of specialists (avoids monopolizing talent in one department).
Weakness: Breaks the unity-of-command concept (employees have two bosses—a functional manager and a product manager); increases ambiguity, power struggles, and stress.
Why Structures Differ: Mechanistic versus Organic Models
Mechanistic Model
High specialization and rigid departmentalization.
Clear chain of command and narrow spans of control.
High centralization and high formalization.
Limited, downward-only information network.
Organic Model
Cross-functional and cross-hierarchical teams.
Wide spans of control and decentralization.
Low formalization and free flow of information.
Participative decision-making and empowered employees.
The Survival of Bureaucracy
Despite the "Bureaucracy is Dead" sentiment, the model survives because:
Large organizational size often necessitates it.
Environmental turbulence can often be managed through standardization.
Technology helps maintain control.
Standardization is achieved by hiring people with extensive educational training who internalize professional rules.
Organizational Design and Employee Behavior
Research indicates the following trends regarding structure and behavior:
Specialization: Generally leads to higher productivity but lower job satisfaction as employees look for more intrinsically rewarding work.
Span of Control: No single best span; its effect on performance depends on individual employee abilities and task structures.
Centralization/Decentralization: Decentralized structures that allow for participative decision-making are positively correlated with higher job satisfaction.
