Product Breakdown Structure: Benefits, and How to Create One

Can managing complex projects with multiple components be a struggle sometimes? The Product Breakdown Structure (PBS) offers a clear solution. PBS is a hierarchical framework that provides a detailed view of a product’s components and sub-components. It simplifies Project Management by breaking down complex products into manageable parts, ensuring better oversight and planning.  

Read this blog to discover how implementing a Product Breakdown Structure can streamline your project processes. Also learn how it helps improve communication and enhance efficiency.

Understanding Product Breakdown Structure (PBS) 

The Product Breakdown Structure (PBS) is a hierarchical framework that outlines the deliverables or outcomes of a project. It helps the project team identify all the components needed to create the final product. Additionally, it ensures that all necessary tasks are clearly defined for successful completion. 

Key Points: 

a) Hierarchical Framework: Organises project deliverables in a structured manner. 

b) Component Identification: Ensures all components needed for the final product are identified. 

c) Task Definition: Clearly defines all necessary tasks for successful completion. 

d) Enhanced Communication: Improves communication among team members and stakeholders. 

e) Risk Management: Helps anticipate and mitigate potential risks. 

f) Progress Tracking: Allows effective tracking of project progress.
 

Key Benefits of PBS 

The key benefits of using a PBS include: 

a) Defining Project Scope: Clearly outlines the scope of the project. 

b) Focusing the Team: Directs the team’s attention to what needs to be produced. 

c) Detailing Product Content: Encourages the team to consider specifics, such as the type of database, the number of records, and the format. 

d) Establishing Quality Criteria: Defines the quality standards for the product, how it will be reviewed, and the skills required for the review. 

e) Creating a Work Breakdown Structure: Serves as a foundation for developing the Work Breakdown Structure (WBS). 

How to Create a PBS? 

We hope that you understand what a Product Breakdown Structure is. Now, it’s time to learn how to make a PBS to have a product log for your project. First, you need to assemble your product development team and begin the process of identifying the products in your project. 

Step 1: Identify Products 

a)  Assemble your product development team. 

b) Each team member lists the products needed to achieve the final deliverable. 

Step 2: Consolidate Product List 

a) Share and combine all individual product lists into one master list. 

b) Remove any duplicate items. 

Step 3: Divide into Related Groups 

a) Organise related products into groups, known as work packages. 

b) For example, in a car project, group all engine-related items (pistons, cylinders, etc.) together. 

c) Write a product description for each item. 

Repeat these steps to ensure a complete collection of products for your project. This process helps you build a structured and detailed PBS, starting from the top-level product (e.g., a car). It then breaks the product down into major components (e.g., engine, chassis) and further into smaller parts.

PBS Example 

The Product Breakdown Structure (PBS) is a versatile tool in product management, originating from the PRINCE2 methodology. It is used to analyse, document, and communicate project outcomes. Consider the example of a project plan for building a book website, illustrated in the image below. 

The PBS starts with the final deliverable, the book website, at the top of the chart. The next level includes the activated site, configured site, and information added. Each element is further detailed and may branch into multiple sub-products at the same level. This continues down to the most granular components. This example is simple, but the complexity of a PBS can vary depending on the project. 

What is Work Breakdown Structure? 

Work Breakdown Structure (WBS) focuses on project activities rather than products. It essentially represents the project’s “to-do list,” highlighting “work” over “things.” 

Some factors of WBS include: 

a) Hierarchical Structure: The WBS provides a hierarchical breakdown of project activities. 

b) Focus on Work: Unlike PBS, which lists products, WBS details the tasks and activities required to complete the project. 

WBS Dictionary: 

a) Similar to a Product Log, a WBS Dictionary can be created alongside the WBS. 

b) It stores detailed information to support the planning process. 

Role in Project Planning: 

a) The WBS forms the foundation of the Project Plan. 

b) It breaks down the project into stages, work packages, and sub-activities within each work package. 

c) The level of detail depends on the project’s complexity. 

Benefits: 

a) Once completed, the WBS ensures that all tasks required to deliver the project outcomes are understood. 

b) It confirms that the task ordering is correct, providing confidence in the project plan. 

Product Breakdown Structure (PBS) vs Work Breakdown Structures (WBS) 

Let’s clarify the difference between PBS and WBS, as they can be easily confused. Both structures share a similar hierarchical format and can be adapted for various purposes depending on the content of the tree diagram. 

The PBS is a hierarchical chart that outlines the products to be produced during a project. It helps understand the product flow and contributes to a more detailed project plan. On the other hand, the WBS is also a hierarchical chart, but it details the work required to complete the project. This includes activities, tasks, or deliverables contributing to the project’s progress. It helps the Project Manager create a workstream, focusing on tasks the project team executes to ensure smooth project execution.  

The key difference is that the PBS illustrates the output of scope management, while the WBS shows the work needed to produce those products. Both structures are crucial for the planning process and essential for effective Project Management.

Conclusion 

Product Breakdown Structure is an essential tool for effective Project Management. Breaking down a product into its individual components provides clarity, ensures all tasks are defined, and improves communication within the team. Implementing a PBS helps streamline the process, leading to successful project outcomes.
