Today, we will discuss the types of organizational structures.

Every company has an organizational structure built around its goals and business objectives. If the work is short-term, the structure should allow for temporary hires and seasonal employment.

However, if the company relies mainly on repeat business and regular tasks, the structure should support activities that help maintain its operation.

Organizational structure is a system that determines employee hierarchy, functions, and workflow, and also provides a transparent and fair reporting system. It is an enterprise environmental factor guiding how an organization runs its operations.

As organizations grow, their requirements change, and the structure must adapt to support its objectives.

Now you might wonder about the relative significance of the organizational structure, the invisible yet vital scaffolding supporting business activity. 

The market is competitive; therefore, organizations must rapidly adapt to market demand and be responsive to shifting business objectives.

Companies with poor organizational structures will not survive.

A well-defined organizational structure helps businesses realize their potential and support their objectives.

For example:

Let us say your company is producing a good. Your customers are satisfied and not very demanding, so what kind of organizational structure would you select?

The functional organizational structure serves this company best because it supports production operations.

Let’s consider another case.

Suppose your organization has ten employees and deals with small projects. As soon as you complete a project, you start looking for the next one.

In this case, what kind of structure would you select?

You would opt for the projectized organizational structure since your company mainly works with temporary projects.

Now, the final case.

Your organization is enormous. The work environment is dynamic and diverse. Customer requirements and market demands frequently change.

What kind of structure would you select?

The functional structure won’t work because it does not allow for quick changes to its operations and isn’t as responsive to market nuance.

You also cannot select the projectized structure. Although it supports a dynamic nature, this isn’t adequate for a large organization. Your company is big, and you need permanent departments to keep your organization functioning smoothly. This is not possible with the classic projectized structure.

Hence, you will select a matrix organizational structure. It combines the qualities of both functional and projectized organizational structures and will support your operations and help achieve your business objectives.

Types of Organizational Structure

An organizational structure guides how activities in your company are carried out to achieve its goals. It determines how information flows within the organization and between departments. It defines the chain of command and job responsibilities.

The organizational structure depends on many factors, such as governing style, leadership style, workflow, hierarchy, and many more.

The PMBOK Guide defines eight types of organizational structures:

1. Organic or Simple Organization

2. Functional or Centralized Organization

3. Multi-divisional Organization

4. Matrix Organization

5. Project-oriented (Composite or Hybrid) Organization

6. Virtual Organization (Network Structure)

7. Hybrid Organization

8. PMO (Project Management Office)

Wikipedia lists six types of organizational structures:

1. Pre-bureaucratic Structure

2. Bureaucratic Structure

3. Post-bureaucratic Structure

4. Functional Structure

5. Divisional Structure

6 Matrix Structure

Some other sources divide them into the following categories:

◉ Simple Organization

◉ Functional Organization

◉ Divisional Organization

◉ Matrix Organization

◉ Team-based Organization

◉ Network-based Organization

◉ Modular Organization

On the Internet, you will find many different types of organizational structures. However, the classifications above are the most popular.

Since this blog follows PMI’s guidelines, we will focus on the PMBOK Guide’s classification and explain the other organizational structures briefly.

Organic or Simple Organizational Structure

Here, you work alone or side by side with another employee.

You may be the only employee in your company.

Instances of this type are a solopreneur, OPC (One Person Company), or a freelancer.

Functional (Centralized) Organizational Structure

Functional organizational structure is the most commonly used organizational structure. Here, the organization comprises various departments; each department has workers with similar skills: sales, marketing, finance, to name a few.

This helps organizations maximize the efficiency of each functional group.

Multi-Divisional Organizational Structure

Here, you may have many functional divisions with a little centralization. Generally, these divisions are independent. Although they will guide a part-time staff, project managers do not have much authority.

Under a multi-divisional structure, the organization is divided into various divisions. Employees with diverse skills are kept together in groups based on a similar product, service, or geographic location. Each division has the resources required to function and can work independently.

Matrix Organizational Structure

Matrix organizational structure is a hybrid of a functional and projectized organizational structure. Here you have two command structures: vertical and horizontal. An employee may belong to a functional group and work on a project, so this structure combines the best of both worlds.

A matrix organizational structure can be of three types:

1. Strong Matrix Structure

2. Balanced Matrix Structure

3. Weak Matrix Structure

Strong Matrix Structure

Strong matrix organizations are closer to a projectized organization. The project managers have the highest authority, control over the budget, and a full-time team reporting to them.

Balanced Matrix Structure

A balanced matrix has properties of both functional and projectized structures. Here, project managers have a low-to-moderate authority and a part-time team. Both the project manager and the functional manager manage the budget.

Weak Matrix Structure

A weak matrix is closer to a functional structure. With a weak matrix, project managers have low authority and no control over the budget; they will have a part-time team.

Project-Oriented (Composite or Hybrid) Organizational Structure

As its name suggests, projectized organization deals with projects. Project managers have a full-time role and comprehensive authority to complete the project successfully. They control the budget and have a full-time team report to them.

A team-based structure is another name for a projectized organizational structure.

Virtual Organization or Network Structure

Many experts call this a virtual corporation. The central organization is connected to outside firms via the internet. The outside firm can be a vendor, client, or associate. This structure helps businesses achieve corporate growth and a greater profit. In a network structure, the organization keeps its core business to itself while adjunct processes are outsourced. 

This structure is also known as a hollow corporation, hollow organization, or network structure.

In a virtual organization, the project manager has a low-to-moderate authority, mixed control over the budget, and they may or may not have a full-time team reporting them.

Hybrid Organizational Structure

True to its name, this structure may use any combination of the organizational structures.

Suppose yours is a functional organization whose typical needs are easily met by conventional departments In some cases, however, your organization will create a separate project team to complete unique tasks.

Hybrid Organization is a mixed structure that serves organizations with diverse needs. Responsibility, authority, and other factors are also mixed depending on the structure.

PMO (Project Management Office)

PMO is also a mixed organizational structure. Here, project managers have the highest authority. They control the budget and have a full team reporting to them.

This concludes the summary of organizational structures.

Next, we will discuss those organizational structures not mentioned in the PMBOK Guide. Note that I am describing these organizational structures for your information only. You will not see any questions in your PMP exam about these types of structures. 

The Simple Structure

This organizational structure is suitable for small organizations in their early stages. They have just started and are still in the development phase. In these companies, authority rests in a single person. These structures have few rules, and work is relatively straightforward.

Some scholars call this a pre-bureaucratic structure.

The Modular Structure

In this structure, the organization outsources some parts of a product.

Note that in the network structure the company outsources the processes, while in a modular structure outsources only a few parts of the product.

Pre-Bureaucratic Structure

Pre-bureaucratic organizations do not have standard procedures and policies. Small-scale and young companies use this structure. This organizational structure has a few employees who handle simple tasks. It has a central command with one decision-maker in the top position.

Communication takes place on a one-on-one basis, and it usually is informal.

Bureaucratic Structure

This organizational structure is suitable for huge organizations with complex operations that need smooth administration. They have standard procedures and processes.

An example of this organizational structure is the food and beverage industry, with strict rules and regulations that govern processes.

Post-Bureaucratic Structure

Post-bureaucratic organizations are quite developed and have complex standards and procedures. These organizations have a central command comprising several board members; decisions are made through a democratic process.

This encourages employee participation, trust, responsibility, and respectful interpersonal relationships.

Key Elements of Organizational Structure

The followings are five key elements of an organizational structure:

1. Job Description

2. Division of Department

3. Chain of Command

4. Span of Control

5. Formalization

Job Description

A job description defines the task managed by each employee of the organization. 

It is the most important element of organizational structure as it distinguishes one role from another and separates and defines the responsibilities.

Division of Department

An organizational structure can have many departments, such as finance, human resources, and quality control.

Each department has a unique set of activities and a department head. Sometimes, departments are known as sections and led by the section head.

Chain of Command

This shows the line of command from top to bottom.

For example, quality control supervisors report to quality control engineers, and quality control engineers report to the quality control head.

However, the head of quality control and human resource are equal and report to the organization’s CEO. 

Span of Control

This shows how many departments the organization has; moreover, it defines how many employees a manager or department head can control.

The span of control determines the chain of command and provides shape to the organizational structure.

Formalization

Formalization defines how employees should behave and communicate through the chain of command. 

Formalization standardizes the workflow in organizations.

The Impact of Growth on Organizational Structure

The structure of an organization cannot be fixed, especially when the business is growing. 

When the company is small or starting up, it will have a simple structure.

As it grows bigger, but still handles a single project at a time, it can function well with a pure projectized organization. 

If the company is creating products and growing, it may shift to a functional organizational structure.

But as the business continues to grow, it cannot rely on a pure project or functional structure. It will require elements of both structures to support its needs. In such cases, the business can have a strong matrix or weak matrix structure.

As the company expands, it will need to have a hybrid structure to support its business objective.

The Advantages of an Organizational Structure

An organizational structure has a well-defined reporting structure, reducing friction among employees by clarifying roles and responsibilities.

Having a proper organizational structure can bring immense benefits to any organization. A well-chosen structure
