The Manager’s Guide to Risk Assessment: Getting It Right

Risk assessment is required for just about all business plans or decisions. As a responsible manager, you need to consider threats to your organization’s resilience. But to determine probability and impact – and reduce your risk – can be a daunting task. Guided by Douglas M. Henderson’s The Manager’s Guide to Risk Assessment: Getting It Right, you will confidently follow a clearly explained, step-by-step process to conduct a risk assessment.



As you embark on the risk assessment process, you could not find a better and more uniquely qualified guide than Douglas M. Henderson. His 20+ years of experience with major consulting firms includes certification as a professional actuary and business continuity planner. His actuarial knowledge makes him an expert in applying mathematical and statistical methods in understandable terms to help organizations to assess and manage risks. He has applied this real-world knowledge of risk to helping businesses prepare for emergencies and business interruptions of all types.

Henderson offers samples and checklists, including case studies using a fictional company in which he conducts a complete qualitative risk assessment and then a complete quantitative risk assessment, then arrives at a set of comparable actions. His explanations and sample problems will help you to:

  • Define risk management terms, such as threat, event, and risk control.
  • Identify threats and determine the worst-case situation your organization could face.
  • Collect information on probability for natural and non-natural threats.
  • Understand the difference between qualitative and quantitative risk assessment.
  • Describe probability and impact levels.
  • Identify exposures and examine specific risk controls.
  • Estimate a financial value for implementing a risk control.
  • Determine when outside professional help is needed.

As an added bonus, Henderson explores the topic of risk controls with you, helping you to evaluate what risk controls will best reduce the probability of disruptive events and reduce their impact should they occur. To insure the best investment of time and money, you will know how to perform a cost-benefit analysis for each possible risk control to make the best choice for your organization.

About the Author



About the Author

Douglas M. Henderson, President of Disaster Management, Inc., has 20 years of experience in management with major consulting firms. In August of 1992, Doug was the key associate of the Emergency Response Team for a consulting firm located in South Miami-Dade County. Inspired by his real-life business experience with Hurricane Andrew and concerned about the lack of preparation within the business community, Doug founded Disaster Management, Inc. in 1993.

Doug has a Degree in Mathematics from the University of Arizona. His professional credentials include FSA – Fellow, Society of Actuaries and CBCP – Certified Business Continuity Professional. Doug is the author of the book Is Your Business Ready for the Next Disaster? and is the author of the Business Continuity Template for Manufacturing and Distribution, the Template for Comprehensive Business Continuity Management, the Continuity of Operations Plan for Colleges and Universities and several other planning templates. Doug is also the co-author of the college textbook Business Continuity and Risk Management: Essentials of Organizational Resilience.

Excerpt from the Preface

My primary purpose in this book is to give you an understanding of the practical procedures required to conduct a risk assessment. Your initial goal in a risk assessment is to focus resources to respond to the threats that are most important to your organization. After this is accomplished, you will be able to develop specific procedures to improve organizational resiliency.

Why? What? How? This book begins by explaining why you should spend the time and energy involved with developing a risk assessment and why a basic understanding of risk management is beneficial to an organization. Next, you will explore what a risk assessment entails and the practical application to an individual organization, and then you will be introduced to two alternative approaches to performing a risk assessment. Finally, you will examine various methods to reduce risk.

Chapter 1: Overview of Risk Management

First, you will examine the progression by which ordinary threats become disruptive events to your organization. You will explore risk, risk management, and risk assessment principles and their importance to any well managed organization.

Chapter 2: Threat Identification

After examining threats from multiple perspectives, you will then learn how to determine the most likely specific threats to be analyzed. Essentially, you will be “identifying the enemy,” which is the first step in dealing with the problem.

Chapter 3: Determining Probability and Impact for Risk Assessment

You will see how to determine the probability of an event materializing and its possible impact upon your organization. Once probability and impact are established, you can determine risk.The chapter also introduces two methods of conducting a risk assessment – a qualitative approach and a quantitative approach. Both approaches are based on the same principles and, when used correctly, both approaches will produce accurate results. The quantitative approach will produce results with more precision than the qualitative approach, but will require some additional effort.

Chapter 4: Qualitative Risk Assessment

You will learn the basic process to conduct a qualitative risk assessment that classifies risks by using little or no mathematics.

Chapter 5: Quantitative Risk Assessment

You will learn the basic process to conduct a quantitative risk assessment that classifies risks by using mathematics.

Chapter 6: Risk Controls: Improving Organization Resiliency

Finally, you will see how to identify and implement risk controls to improve organizational resiliency. Once you have reviewed these principles of risk reduction, you will be ready to select and analyze possible risk reduction measures from a comprehensive list of risk controls.


In the appendices, you will find two sample risk assessments; one qualitative risk assessment and one quantitative risk assessment.

Each risk assessment is for a sample fictitious company that will provide you with a working example of how a risk assessment is conducted. Essentially, this allows you to apply the principles that you have learned in this book to a realistic situation. It will be a useful guideline when you decide to conduct a risk assessment for your organization.

While this book is directed primarily to managers and executives, you will find it useful if you are a business continuity (or organizational resilience) professional or participating in a professional training course. I am confident that when you complete your readings, you will be sufficiently versed to undertake a risk assessment.

Excerpt from Chapter 2: Threat Identification

You will rarely be able to predict the exact timing or exact cause of the next disaster to strike your organization. However, knowing the most likely threats and preparing to respond to those threats will help to minimize the impact to your organization or perhaps even prevent the event from occurring.

This chapter will help you to:

  • Know how to identify threats to your organization.
  • Group threats into logical categories for examination.
  • Determine the worst-case situation your organization could face.
  • Select specific threats for examination.

2.1 Identifying Threats

The term threat includes many types of events and disruptions, including:

  • • Natural threats (e.g., blizzard, earthquake, or flood).
  • Accidental man-made threats (e.g., electrical outage, equipment failure, loss of data).
  • Intentional man-made threats (e.g., fight, strike, loss of buyers).

Threats can be very significant disruptive events or relatively minor disruptive events. Sometimes minor disruptive events can become much more serious disruptive events. For example, assume that a water pipe bursts in a common bathroom within your organization’s building (a minor event), but nobody knows where the water shutoff valve is located. While everyone is searching, water now damages the entire building including your work area – the minor event has manifested into a significant disruptive event! The lesson here is that when you examine threats, it is wise not to restrict your focus to significant disruptive events.

As you work to identify all threats, I recommend that you view threats on a geographical basis. You should consider and list the common (and not so common) threats that are located within the following:

  • The organization (e.g., equipment failure, workplace violence).
  • The building or immediate area (e.g., hazardous release, fire).
  • The community (e.g., civil disturbance or riot, electrical outage).
  • The geographical region (e.g., earthquake, flood, transportation disruption resulting in a supply chain disruption).

2.2 Grouping Threats

As you begin to narrow down individual threats to a manageable number, I recommend grouping individual threats into specific categories. For many organizations, a preponderance of threats relates to physical security (e.g., bomb threat, civil disturbance, hostile intruder, internal criminal acts, external criminal acts, workplace violence). Typically, such threats are examined under the security category grouping. Many security risk controls such as a perimeter security system or security cameras will protect against a wide variety of criminal events.

Another example of threat grouping is technology threats. Typically, you will examine technology threats for the major functional areas of technology (such as alternate site plans, communications, data center protection and recovery plans, information or data management, and  information security). It is important to examine all areas of technology. I have seen instances where planning for the data center and alternate site is very good but information management or information security plans are inadequate. Such inconsistent planning can arise when different people with different skill levels are assigned to the different functional areas. I have also observed this problem in smaller  data centers where one person covers everything. Every individual (myself included) has different skill levels and, frankly, different levels of interest within the different functional areas.

You will also find logic in grouping medical threats. Many medical risk controls such as personal protective equipment and social distancing policies are effective in limiting contamination of healthy individuals by infected individuals. Whether the threat comes from a pandemic outbreak, respiratory infection, or common cold, practices such as not touching your face with your hands and using speaker phones will reduce the likelihood of contamination. In other words, a pandemic plan will be at least partially effective in combating other general medical emergencies, and with minor modifications can be made more effective…
