Guide to Understanding and Answering Questions on Risk Breakdown Structure (RBS)

What is Risk Breakdown Structure (RBS)?
Risk Breakdown Structure (RBS) is a hierarchical framework that outlines the potential risks associated with a project. It systematically breaks down risks into distinct categories, providing a clear structure that helps in identifying, assessing, and handling these risks.

Why is RBS Important?
Risk management is crucial for the successful completion of a project. Understanding the various risks and structuring them helps project managers prepare and implement strategies to minimize the impact of these risks. RBS is a beneficial tool that boosts the efficiency of risk management processes and supports better decision-making.

How Does RBS Work?
RBS starts with a top slice representing the full project, which is further divided into lower levels of risks divided by categories (e.g., technical, project management, organizational). Risks can be further broken down to as many levels as necessary until all potential risks have been identified. This hierarchical structure makes it easier to understand and manage project risks.

CAPM - Risk Breakdown Structure (RBS) Example Questions

Test your knowledge of Risk Breakdown Structure (RBS)

Question 1

Your company is working on a project to construct a new building. You have identified different types of risks and decided to organize them using RBS. Which of the following risks belongs to the 'Technical Risk' category?

The project may face legal issues due to non-compliance. There could be an increase in labor costs. A key team member may leave the project. The materials used in construction may not meet the quality standards.

Correct Answer: The materials used in construction may not meet the quality standards.

Among the given options, 'The materials used in construction may not meet the quality standards.' falls under the 'Technical Risk' category as it relates directly to the technical aspects of the building construction, specifically to the quality of the construction materials. Other options indicate different types of risk. For example, 'A key team member may leave the project.' represents a Human Resource risk as it's associated with personnel involved in the project. 'There could be an increase in labor costs.' signifies a Cost risk because it's related to project budgetary concerns. And finally, 'The project may face legal issues due to non-compliance.' implies Compliance, Legal or Regulatory risk, as it pertains to the legal requirements the project must adhere to.

Question 2

You are developing an RBS for a city's waste management project. Which risk would fall under the category of 'Public Relations Risks'?

Risk of breach in waste treatment equipment Risk of non-compliance with environmental regulations Risk of public dissatisfaction over temporary disruption of services Risk of mismanagement of waste collection routes

Correct Answer: Risk of public dissatisfaction over temporary disruption of services

The 'Risk of public dissatisfaction over temporary disruption of services' falls under the category of 'Public Relations Risks' because it directly concerns the reputation and public perception of the project. On the other hand, 'Risk of mismanagement of waste collection routes' is more of an operational or logistics risk. 'Risk of breach in waste treatment equipment' would be considered a technical or equipment risk. And 'Risk of non-compliance with environmental regulations' would be considered a legal or compliance risk. Therefore, these other answers do not pertain to public relations.

Question 3

During the project planning phase, the project team has identified potential risks and has grouped them into categories. Which of the following best represents the purpose of a Risk Breakdown Structure (RBS)?

A hierarchical representation of project risks that helps in organizing and understanding the risks based on their characteristics A matrix that identifies the probability and impact of risks without any grouping A sequential list of potential risks in a project without any categorization A graphical representation showing the timeline of different risks throughout the project

Correct Answer: A hierarchical representation of project risks that helps in organizing and understanding the risks based on their characteristics

A Risk Breakdown Structure (RBS) is a hierarchical representation of project risks that helps in organizing and understanding the risks based on their characteristics. It allows for grouping risks into categories to provide a clear and structured view of the potential risks associated with the project. The other answer options do not accurately describe the purpose of an RBS. They either focus on different aspects of risk management or provide incomplete or incorrect definitions.
