Nan picked up the last chunk of cookie and ate it. Peter and Trish had long ago finished theirs, but Nan liked making cookies last. "The critical thinking fallacies were my favorites," she said. "I like learning how to think more clearly."
Peter sipped his coffee. "Mmm." He swallowed. "But how do we avoid those fallacies?"
Nan had an idea. "Maybe we should inspect our project plans, like we inspect components."
Trish was intrigued. "Yeah, and I know what I'd put at the top of the checklist."
"OK, I'll bite," said Peter. "What?"
Trish was ready. "The Nine Project Management Fallacies."
Not a bad idea. These last three fallacies (Part IV of a little catalog of the fallacies of project management) are errors of critical thinking. For Part III, see "Nine Project Management Fallacies: III," Point Lookout for December 28, 2005.Non-random polling
might provide comfort,
but it's hardly
- The Normative Fallacy
- This fallacy holds that when we ask some people their opinions, and most of them agree, then they're correct. Usually we select people non-randomly, choosing those who will give us desirable answers, or those we can trust, or those of high rank.
- Non-random polling might provide comfort, but it's hardly scientific, and it almost always leads to biased conclusions.
- To get truly useful polling data, you must poll people randomly.
- The Availability Heuristic
- In risk management, we often estimate the probabilities of certain events. We're using the Availability Heuristic[*] when we estimate these probabilities by sensing the difficulty of imagining or understanding the string of events that lead to the risk.
- For instance, when we ask people whether death resulting from being attacked by a shark is more or less likely than from being hit by falling airplane parts, they usually answer that death by shark attack is more likely. Actually, death from being hit by falling airplane parts is 30 times more likely, but people are fooled because it's easier to imagine shark attacks, which are more common.
- Estimating probabilities is unlikely to produce reliable results. For this reason, the Availability Heuristic is usually considered an example of a cognitive bias. Use real data, or use huge error bars.
- The Grandiosity Fallacy
- Confronting a problem, we sometimes address a generalization of the problem instead, hoping to solve a host of similar problems, and thereby solving the original problem almost "for free." Rarely does the reality match the wish.
- Grandiosity usually generates two kinds of trouble. First, it's often more expensive and time-consuming than originally estimated. Second, the people of the organization rarely want the general solution. If they did, they probably would have sought it in the first place.
- Sometimes customers don't know the value of the general solution, and telling them about it might produce a better outcome. But usually they want only what they asked for. Work with them on that first.
Track the incidence of these nine fallacies in your organization. Use them to inspect project plans. Probably your projects will have fewer surprises, or at least you'll be just a little less likely to be hit by falling airplane parts. First in this series Top Next Issue

- Declaring Condition Red
- High-performance teams have customary ways of working together that suit them, their organizations,
and their work. But when emergencies happen, operating in business-as-usual mode damages teams —
and the relationships between their people — permanently. To avoid this, train for emergencies.
- Nine Positive Indicators of Negative Progress
- Project status reports rarely acknowledge negative progress until after it becomes undeniable. But projects
do sometimes move backwards, outside of our awareness. What are the warning signs that negative progress
might be underway?
- Communication Traps for Virtual Teams: II
- Communication can be problematic for any team, especially under pressure. But virtual teams face challenges
that are less common in face-to-face teams. Here's Part II of a little catalog with some recommendations.
- Projects as Proxy Targets: II
- Most projects have both supporters and detractors. When a project has been approved and execution begins,
some detractors don't give up. Here's Part II of a catalog of tactics detractors use to sow chaos.
- On the Risk of Undetected Issues: II
- When things go wrong and remain undetected, trouble looms. We continue our efforts, increasing investment
on a path that possibly leads nowhere. Worse, time — that irreplaceable asset — passes.
How can we improve our ability to detect undetected issues?

- When we disagree about abstractions, such as a problem solution, or a competitor's strategy, the cause can often be misunderstanding the abstraction. That misunderstanding can be a conceptual mondegreen. Available here and by RSS on December 20.
- And on December 27: On Assigning Responsibility for Creating Trouble
- When we assign responsibility for troubles that bedevil us, we often make mistakes. We can be misled by language, stereotypes, and the assumptions we make about others. Available here and by RSS on December 27.

- Person-to-Person Communications: Models and Applications
- When we talk, listen, send or read emails,
read or write memos, or when we leave or listen to voice mail messages, we're communicating person-to-person.
And whenever we communicate person-to-person, we risk being misunderstood, offending others, feeling
hurt, and being confused. There are so many ways for things to go wrong that we could never learn how
to fix all the problems. A more effective approach avoids problems altogether, or at least minimizes
their occurrence. In this very interactive program we'll explain — and show you how to use —
a model of inter-personal communications that can help you stay out of the ditch. We'll place particular
emphasis on a very tricky situation — expressing your personal power. In those moments of intense
involvement, when we're most likely to slip, you'll have a new tool to use to keep things constructive.

- Ten Project Management Fallacies: The Power of Avoiding Hazards
- Most of what we know about managing projects is useful and effective, but some of what we know "just ain't so." Identifying the fallacies of project management reduces risk and enhances your ability to complete projects successfully. Even more important, avoiding these traps can demonstrate the value and power of the project management profession in general, and your personal capabilities in particular. In this program we describe ten of these beliefs. There are almost certainly many more, but these ten are a good start. We'll explore the situations where these fallacies are most likely to expose projects to risk, and suggest techniques for avoiding them. Read more about this program. Here's a date for this program:
- 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.
