In a report released in June of 2014, the U.S. Chemical Safety Board explained how undetected issues in the blowout preventer, including miswiring and design flaws, led to the disaster. The report also states that these issues could be present today in blowout preventers in widespread use throughout the industry, and that additional blowout preventer failures are possible. The CSB Web site offers a marvelous video, including computer animation of the failure. Image courtesy U.S. Chemical Safety Board.
As we saw last time, the difference between a risk and an issue is that risks are adverse events that might or might not happen. They are uncertain. On the other hand, issues are adverse events that have already arisen, or are certain to do so. Undetected issues are especially problematic when we treat them as risks, instead of mounting serious efforts to uncover them.
Let's now explore tactics for uncovering undetected issues. The general principle underlying all these approaches is an obvious one: Look for undetected issues in the places where you're most likely to find them.
- Involve the customer in development — from the beginning
- When developers and customers collaborate, they educate each other. Customers don't always know what they want or need. Sometimes they think they know, but they're mistaken. Still, customers can make valuable contributions to development processes, and participation in development helps refine their knowledge of what they want or need. The sooner this happens, the closer the product comes to delighting the customer. And when this mutual education doesn't happen — or when it happens too late — we sometimes discover issues only after the product is delivered.
- Use what you're building — early
- Actual usage is Actual usage is the method
most likely to expose the
problems that arise
in actual usagethe method most likely to expose the problems that arise in actual usage. Use what you're building (or parts thereof) as early as possible, or recruit actual users to do so. If needed, install placeholders for incomplete components. Placeholders are usually worth the investment, because early usage that exposes serious problems can reduce rework. - Exploit organizational history
- In retrospectives, note the occurrence of undetected issues, the time it took before they were detected, and the cost of not having detected them promptly. Review the observations for patterns. Apply this information to future and ongoing efforts, checking for repetitions of these patterns, and incorporating into designs of products, services, projects, controls, and procedures, clever mechanisms that will signal the presence of any of these patterns. Use the cost information to set the levels of these investments.
- Account for the effects of cognitive biases
- Cognitive biases are patterns of thinking that lead to systematic deviations from rationality and objectivity. They can cause us, for example, to dismiss indications of undetected issues in products or projects. Learn about cognitive biases and incorporate safeguards into your processes to reduce the impact of cognitive biases.
- Test with undetected issues in mind
- Tests and inspections typically focus on determining whether the items tested meet requirements and quality standards. That isn't enough. If you have evidence of patterns of undetected issues in earlier work, broaden the testing focus to check for undetected issues. If you're unaware of patterns of undetected issues, make some brilliant guesses.

Resuming Projects: Team Morale
- Sometimes we cancel a project because of budgetary constraints. We reallocate its resources and scatter
its people, and we tell ourselves that the project is on hold. But resuming is often riskier, more difficult
and more expensive than we hoped. Here are some reasons why.
The True Costs of Cost-Cutting
- The metaphor "trimming the fat" rests on the belief that some parts of the organization are
expendable, and we can remove them with little impact on the remainder. Ah, if only things actually
worked that way...
Deep Trouble and Getting Deeper
- Here's a catalog of actions people take when the projects they're leading are in deep trouble, and they're
pretty sure there's no way out.
Power Distance and Teams
- One of the attributes of team cultures is something called power distance, which is a measure
of the overall comfort people have with inequality in the distribution of power. Power distance can
determine how well a team performs when executing high-risk projects.
Anticipating Absence: How
- Knowledge workers are professionals who "think for a living." When they suddenly become unavailable
because of the pandemic, we consider substituting someone else. But substitutes need much more than
skills and experience to succeed.

- The Power Affect: How We Express Our Personal Power
Many
people who possess real organizational power have a characteristic demeanor. It's the way they project their presence. I call this the power affect. Some people — call them power pretenders — adopt the power affect well before they attain significant organizational power. Unfortunately for their colleagues, and for their organizations, power pretenders can attain organizational power out of proportion to their merit or abilities. Understanding the power affect is therefore important for anyone who aims to attain power, or anyone who works with power pretenders. Read more about this program.

- Bullet Points: Mastery or Madness?
Decis
ion makers in modern organizations commonly demand briefings in the form of bullet points or a series of series of bullet points. But this form of presentation has limited value for complex decisions. We need something more. We actually need to think. Briefers who combine the bullet-point format with a variety of persuasion techniques can mislead decision makers, guiding them into making poor decisions. Read more about this program.
