Operations Risk Assessments



Are you afraid of what you will see when you look in the mirror?




Many businesses fail to understand the benefits of performing proactive operations risk assessments.

Do any of the following sound familiar?

  • Organic Operations Risks – Have you ever wanted to ask; “why do we do this this way?” and know the answer is going to be; “I don’t know, it’s just the way it’s done.”
  • Market Risks – Your new product is about to be released. “We were so busy we didn’t recognize that the market had shifted until it was too late to recover.”
  • Hero Employee Risks – What could be wrong with an employee who goes above and beyond and always volunteers? “She was the best employee we had.” “We didn’t know what to do when she resigned.”

This is just a small sample of operations risks that could impact the sustainability of a business. If you don’t identify risks early, you can’t avoid or mitigate them and eventually they may disrupt your operations. Diligent Operations Self Assessment Training and Independent Operations Assessments examine 400 operations infrastructure touch points. So go ahead… look in the mirror. You might not like what you see but at least you’ll know where all the warts are! An operations assessment may be your least expensive form of insurance and the fastest way to optimize the efficiency of your operations.

The Determined Entrepreneur - Book

ZRalph Waldo Emerson, the 19th Century American writer and philosopher, wrote about the power of the individual and the benefits of following your own path in life. His work might have defined the modern entrepreneur. In his essay “Self –Reliance” Emerson says; “Life is a journey, not a destination. The Determined EntrepreneurThe Story of Dr George Tinsley and the Values that Guided His Journey to Success looks at the values that guided one of America’s most improbable entrepreneurs on his life journey. By following George Tinsley’s amazing journey out of poverty the reader is able to experience in a unique way how a truly determined person can overcome tremendous obstacles and achieve a lifetime of success.


If you were to bet on a person who was likely to succeed in life you would never have bet on George Tinsley. The odds against his success would have seemed far too great to be overcome. To follow his journey, George Tinsley had to overcome an environment of extreme poverty while growing up in one of the toughest inner city neighborhoods in an era of open racial intolerance. By letting the values he learned early in life serve as guides throughout his life, George Tinsley was able to overcome the circumstances of his childhood to beat the odds and achieve great success as a serial entrepreneur.


George Tinsley’s life proves that success doesn’t come from luck alone. Luck might explain one or even two significant accomplishments but becoming a serial entrepreneur doesn’t come from luck but from the repeated application of a set of guiding principles that lead you to achieve one goal after another. The principles that became his guiding values can be learned by anyone, even at a young age, even in the worst of circumstances. What were the values that that propelled this serial entrepreneur?

img1It is possible for anyone to learn and apply the entrepreneurial values that can bring success in their own life. Success comes from applying these values not once but over and over again throughout your life. Entrepreneur examines these values. Values like making good decisions about the path you choose to follow, sustaining your self determination regardless of your life circumstances, setting personal goals and your willingness to work hard to achieve those goals. A successful entrepreneur develops a unique mindset that allows them to pursue their goals even in the face of great adversity. Few people start their journey with as little as George Tinsley but his life proves that it’s not where you start your journey that matters. It’s the values you take along with you on your journey that will determine how far you get in life.

img2How many sports stories do you hear that end once the athlete wins the big game or achieves their goal of making it onto the championship team. The problem with these stories is that they end once the big game has been played or the athlete makes the team. It’s like the big game was the peak of the athlete’s career and their story ends once the game is over. You hear about the hard work and talent it took to win the championship but is that really where their story ends? After hearing one of these stories do you ever feel like this may only be the point where the athlete’s real story begins… but their full life story is rarely told and you’re left hanging, wondering what this success in sports will mean later in the athlete’s life. Entrepreneur shows the reader what happens when a determined athlete looks at their retirement from sports as the beginning of their career instead of the end.


Does an athlete’s willingness to work hard to succeed in sports end once they stop playing or can the values that brought their success in sports be used to achieve even greater things later in life? Does their success end once their athletic skills begin to fade or can they convert these values into entrepreneurial values that become a springboard for other things? The problem with most sports stories is that the story ends when the game is over. George Tinsley’s story begins as a sports story but ends as a success story about business, community and family.


To reach a high level of success in sports an athlete has to bring more than skill to the game. They have to learn the value of hard work and determination, risk taking and the ability to overcome obstacles. These values are similar to the entrepreneurial values they will need to succeed in business in the next stage of their career. Unfortunately, not all athletes are able to convert their success in sports into entrepreneurial success. For some athletes, their entrepreneurial values seem to fade along with their athletic skills. Some professional athletes are able to convert the values of hard work and determination that brought success in their athletic career into stepping stones that will further propel them into successful careers as businessman and entrepreneurs. Because most people understand the work it takes to become a great athlete, George Tinsley’s life story provides an example of how anyone can apply these values in their own life.

George Tinsley’s sports story is a great one… but his life story is even greater. He has accomplished many things in his life. Today, George Tinsley owns and operates almost eighty restaurants and other businesses. He has had an exciting life as a NCAA basketball champion and professional athlete and Kentucky Wesleyan College has acknowledged his accomplishments by awarding him an honorary PhD. But these accomplishments understate his poor beginnings and the improbable journey his life has taken. His story is highly motivational, but more importantly it tells the reader, there is no secret to success, just a set of entrepreneurial values that anyone is able to learn and apply in their own life.


img3Each chapter of Entrepreneur describes one of these entrepreneurial values and explains why it is important to success. The chapter then presents another portion of George Tinsley’s life, demonstrating how the value was learned or the role it played in his success. Because his life is presented in context, the reader will be able to see how these values were applied consistently throughout his life. Success comes from applying these values over and over throughout life.

Operations Due Diligence - Book

Operations Due DiligenceMost investors have a trusted CPA and attorney to help them perform their M&A due diligence. Unlike financial and legal due diligence, which are founded on the well established principles of law and accounting, there are no similar principals to guide an operations due diligence (ODD)… and this is where most investors would agree they make their greatest mistakes. Making ODD a leading cause of M&A failures. Most investors aren’t even able to define what constitutes an effective operations due diligence and most businesses aren’t prepared for a true operations assessment. Operations Due Diligence – An M&A Guide for Investors and Business, helps investors assess risk and the potential for long term sustainability of the business.


An effective due diligence requires the exploration of the financial, legal, and operations facets of a business. Financial due diligence relies heavily on the past performance of the business and legal due diligence is primarily concerned with the current structure and liability of the business. Neither of these concentrates on the operations infrastructure needed to support the future performance of the business. Operations Due Diligence solves this problem.


It’s hard to understand why any investor would consider putting millions of dollars into a business based solely on the financial and legal assessments without first asking some tough questions about the long term sustainability of the business. Operations due diligence assesses the latent operations risks that could impact the future success of the business. Looking at the financial and legal side of the business, without also performing an extensive operations risk assessment means the investor is entering an investment with tremendous potential risk…  and a great leap of faith.  Operations Due Diligence solves this problem.
On the other side of the coin are the businesses that are vying for scarce investment funds. While managers are wrestling with the day to day operation of their business they are simultaneously trying to position the business to compete for the funds needed for growth. While focusing on their day to day decisions, it’s easy to fall into an ad hoc mode of operation while losing focus on the development of the businesses operations infrastructure. Management is doing whatever it takes to get today’s problem solved and are left to worry about tomorrow’s problems when they occur. There hasn’t been a guide that helps them prioritize the activities that will position the business to compete for investment funds  or prioritize their infrastructure improvement activities. They proceed with the potential that they’ve missed something… and a great leap of faith that they will meet an investor’s requirements when the day for a due diligence eventually arrives. Operations Due Diligence solves this problem.
Operations Due Diligence isn’t just another dull management book either. It makes extensive use of historic examples and stories, making it understandable, memorable and entertaining so that the reader will easily grasp and retain the information. Operations Due Diligence provides 400 due diligence questions that help the reader explore risk across nine operations infrastructure areas. The extensive use of historic examples puts each question in a context that will supplement the reader’s own experiences. A typical question is; “What is the organizational structure of the business”? Operations Due Diligence answers this question by first telling the story of Cavalry Officer Roberts as an example of why he created the Roberts Rules of Order to create structure. Each of the questions in Operations Due Diligence is described in detail, and placed in historic context in this manner. Investors concerned with the sustainability of a business and managers trying to position their business to qualify for an investment will find Operations Due Diligence is a valuable reference they will use over and over.

CHAPTER 1 – DUE DILIGENCE: Chapter 1 describes the need for due diligence and explains the difference between legal, financial, and operations due diligence. Legal and financial due diligence are based on the well established principals of law and accounting, however, no such well founded principal exists to support operations due diligence. Chapter 1 describes the methods for exploring the operations infrastructure to identify hidden risks and opportunities during an operations due diligence.
CHAPTER 2 – THE DUE DILIGENCE PROCESS: Chapter 2 is a brief overview of the due diligence process with emphasis on the requirements for conducting an operations due diligence and the role of the due diligence team. Due diligence is presented as a three step process (planning phase, on-site assessment phase, and the analysis and reporting phase).
CHAPTER 3 – INFRASTRUCTURE ASSESSMENT AREAS: Chapter 3 presents nine operations infrastructure areas that need to be explored during an operations due diligenceand describes what constitutes an infrastructure (processes, procedures, work flows, transaction points, etc.). These infrastructure areas are the subject of each of the chapters in Part 2.
CHAPTER 4 – ASSESSMENT OF THE CUSTOMER SATISFACTION INFRASTRUCTURE: Satisfied customers become repeat customers; they remain loyal to a business they feel has given them value. And yet, businesses often underestimate how important customer satisfaction is to their success. Operations Due Diligence looks at the role of customer satisfaction as an integral element across all areas of the business. It explores the importance of functions such as product support, requirements baseline control, quality management systems and employee training.
CHAPTER 5 – ASSESSMENT OF THE PRODUCTION INFRASTRUCTURE: All products can represent a high risk investment if the business doesn’t have sufficient production capability supported by a sound production infrastructure in place to bring the product fully to market. If the production capability of the business is assessed as a weak area, an investment strategy which includes updating the production infrastructure could offer a great opportunity for the investor.
CHAPTER 6 – ASSESSMENT OF THE INFORMATION MANAGEMENT INFRASTRUCTURE: It would be a tremendous understatement to say that all businesses today are information intensive. The information management infrastructure includes the electronic tools and data that form the backbone of the business and could represent a tremendous investment risk if assessed as a weak area of the business. Chapter 5 also touches on important sustainability subjects such as exploring a business’s disaster recovery processes.
CHAPTER 7 – ASSESSMENT OF THE SALES AND MARKETING INFRASTRUCTURE: Chapter 7 presents the sales and marketing infrastructure as a cross function of the entire business organization and discusses the assessment of the businesses primary goal; to sell products and make a profit. Chapter 7 provides methods for exploring the sales pipeline and products used to define the products and markets including the use of competitive and strategic analysis as assessment tools.
CHAPTER 8 – ASSESSMENT OF THE ORGANIZATIONAL INFRASTRUCTURE: Chapter 8 discusses the exploration of the formal and informal organizational structure of a business. This includes the legal structure, the organization chart that forms the command and control structure, plus the informal structure that becomes the corporate culture of the business. An assessment of the organizational infrastructure explores the working environment of the business.
CHAPTER 9 – ASSESSMENT OF THE PERSONNEL INFRASTRUCTURE: Many businesses state; our employees are our most important asset, but what does this really mean? An assessment of the personnel infrastructure is an exploration of the working relationship between the business and its employees including an assessment of the competency of the management team. Chapter 9 also includes subjects such as the assessment of employees motivation and compensation plus hiring, firing and everything in between.
CHAPTER 10 – ASSESSMENT OF THE FINANCIAL INFRASTRUCTURE: Financial due diligence is an assessment of the current financial status of the business but this type of assessment doesn’t tell an investor anything about the financial command and control structure of the business. Chapter 10 discusses the assessment of the financial infrastructure that forms the financial operations framework of a business. Operations due diligence of the financial infrastructure is not an assessment of the current financial status of the business. It is an assessment of the continuing financial operations of the business.
CHAPTER 11 – ASSESSMENT OF THE LEGAL INFRASTRUCTURE: Legal due diligence is an assessment of the current legal status of a business but this type of assessment doesn’t tell anything about the legal command and control structure of the business. Chapter 11 discusses the assessment of the legal infrastructure that forms the legal operations framework of a business. The legal infrastructure guides the legal operations of a business on a continuing basis. It includes all of the activities used to protect the business from legal risk and legal liabilities. Exploration of this area tells an investor, not the current legal status but the controls, such as program/project management and cost account management that will protect the business against future legal liability.
CHAPTER 12 – ASSESSMENT OF THE INSTITUTIONALIZED PROCESSES: Chapter 12 helps investors understand and explore the formalized policies and procedures that a business follows and the formalized method that guide their operations. Methods such as ISO, CMMI, Six Sigma, Enterprise Risk Management (ERM) or Quality Management Systems (QMS) can represent a significant opportunity for an investor once they are understood or they can represent significant risk if the business fails to qualify for a market driven process requirement.
