  • True
  • False

Answer: False

Explanation: An RBS is a critical tool in the risk management plan, helping to identify and categorize risks effectively.

Multiple Select: A Risk Breakdown Structure can be classified into multiple levels based on which of the following factors?

  • A. Project size
  • B. Risk impact
  • C. Risk probability
  • D. Project duration

Answer: A, B, C

Explanation: The RBS classifies risks into various levels depending upon project size, risk impact, and risk probability, helping in prioritizing and managing risks.

True or False: The RBS and the risk management plan are the same thing.

  • True
  • False

Answer: False

Explanation: The RBS is a risk identification and categorization tool, whereas the risk management plan is a plan that outlines how risks will be managed throughout the project.

Single Select: What is the FIRST step in developing a Risk Breakdown Structure?

  • A. Identify risks
  • B. Classify risks
  • C. Allocate resources
  • D. Develop a risk management plan

Answer: A

Explanation: The first step in creating an RBS is to identify risks; only then can they be classified and managed.

True or False: The Risk Breakdown Structure often overlaps with the Work Breakdown Structure.

  • True
  • False

Answer: True

Explanation: While they are two separate components, the information in the RBS often overlaps with the Work Breakdown Structure (WBS), as they both deal with aspects of project management.

Multiple Select: Who should be involved in the development and revision of a Risk Breakdown Structure?

  • A. Project manager
  • B. Project team members
  • C. Risk manager
  • D. Stakeholders

Answer: A, B, C, D

Explanation: Everyone involved in the project, including the project manager, team members, risk manager, and stakeholders, should participate in the creation and revision of the RBS to ensure thorough risk identification and categorization.

Interview Questions

What is a Risk Breakdown Structure (RBS)?

A Risk Breakdown Structure (RBS) is a hierarchical representation of risks, organizing them from higher levels to lower levels. This way, the sources of risk can be identified and actions can be prioritized.

How does the RBS support the risk management plan?

The RBS assists in the risk identification process which is a crucial step in the risk management plan. It helps in identifying, categorizing, and prioritizing the risks which aid in making the risk management plan more comprehensive and effective.

Can the RBS be used in both qualitative and quantitative risk analysis?

Yes, the RBS can be used in both qualitative and quantitative risk analysis. In qualitative analysis, it aids in identifying and ranking risks while in quantitative analysis, it assists in estimating the probability and impact of risks.

What is the overall objective of using an RBS in risk management?

The main goal of an RBS in risk management is to facilitate better understanding, communication, and management of risks throughout the project life cycle.

Who is the key stakeholder in creating the RBS?

The key stakeholder in creating the RBS is the project manager, however, the entire project team and other stakeholders should contribute to ensure all possible risks are identified and categorized properly.

Why is visualization important to the Risk Breakdown Structure?

Visualization in RBS helps stakeholders to easily understand the complexity of risks by categorizing and breaking down risks hierarchically and improving clarity in risk reporting.

Is the usage of RBS mandatory in risk management planning?

While using RBS is not mandatory, it is highly beneficial and recommended as it aids in comprehensive risk identification, organization, and prioritization which makes the risk management process more effective.

In which phase of the risk management process is the RBS used?

The RBS is primarily used in the risk identification phase of the risk management process.

Can the RBS be updated during the project lifecycle?

Yes, the RBS should be considered a living document, meaning that it should be updated as new risks are identified during the project lifecycle.

What happens if risks are not properly categorized in the RBS?

If risks are not properly categorized in the RBS it could lead to misunderstandings about the source, type, and significance of risks. This can subsequently hamper the risk response planning and may lead to ineffective risk management.

How does RBS differ from the Risk Register?

While both RBS and Risk Register are tools in risk management, they serve different purposes. The RBS is used for identifying and categorizing risks, while the Risk Register is used for documenting and tracking all aspects of each risk identified.

Can RBS help in risk response planning?

Yes, RBS can help in risk response planning by providing a clear structure and understanding of risks, which in turn can guide the formulation of risk response strategies.

What are the main elements in a Risk Breakdown Structure?

The main elements in a Risk Breakdown Structure are the risk categories (sources of risks), the individual risks within each category, and the hierarchical structure which shows how the risks are related from higher to lower levels.

What is the benefit of RBS regarding communication among stakeholders?

The RBS can facilitate communication among stakeholders by providing a clear and organized visual representation of risks, making it easier for all parties to understand and discuss the risk landscape of the project.

Can the RBS assist in risk monitoring and controlling?

Yes, the RBS can assist in risk monitoring and controlling by providing an organized structure that allows the project team to track the status and evolution of each risk throughout the project life cycle.
