Peter loved his chocolate chip cookies, but he liked this conversation with Trish and Nan even more. Holding his hands over the side of his chair to brush the cookie crumbs off them onto the ground, he added "And his discussion of wishful thinking was really insightful."
Nan broke off a tiny chunk of her cookie, ate it, and sipped her coffee. "Mmmm, I thought so too," she said. "Knowing that we fall into these fallacy traps because of our humanness made me more accepting of it, less guilty."
Trish was puzzled. "Yeah, but how does that help the project?"
"That's just it," said Nan. "Knowing that the fallacies are part of being human makes it easier to acknowledge these errors when we make them."
Peter finished Nan's thought. "And that way we can own up to them faster, maybe even before they do any damage."
Fallacies aren't just false. Because they have a deep connection to what we are as human beings, they'll never go away. Here's Part III of a little catalog of the fallacies of project management. For Part II, see "Nine Project Management Fallacies: II," Point Lookout for December 14, 2005, and for Part IV, see "Nine Project Management Fallacies: IV," Point Lookout for January 11, 2006.
- The Fungibility Fallacy
- The Fungibility Fallacy holds that each person produces one hour of output in one hour, and that we can substitute people for one another. Terms that suggest this fallacy are man-month headcount and FTE.
- Often, only a few people can perform certain tasks. Using the project management tools that distinguish the skills of large numbers of unique individuals takes time and effort, and even then they produce somewhat fictitious results.
- And running "lean and mean" makes the problem worse. If you count the cost of delays and lost market windows due to overloading key people, running a little "fatter and kinder" might actually be more profitable.
- The Linearity Fallacy
- Fallacies have
a deep connection
to what we are
as human beings
- This fallacy holds that the human effort required to execute a project scales in proportion to project attributes such as project size or total budget.
- Not only do operating costs per unit of output grow rapidly with project size, but the converse is also true: costs decline unexpectedly slowly as we scale the project down in size. This happens because we have difficulty abandoning control processes as we move down in size. We lose in both directions.
- Project management is an inherently nonlinear activity. The complexity of an effort grows not in proportion to the effort, but combinatorially with the size of the effort, following the growth in the number of possible person-to-person interactions with increasing team size.
These two fallacies both arise because of our hopes and wishes. We long for a world where we can substitute any person for any other; for a world where doubling resources halves the schedule. But longing doesn't make it so. In the next and final installment of this series we'll look at fallacies that arise from failures of critical thinking.

- Finger Puzzles and "Common Sense"
- Working on complex projects, we often face a choice between "just do it" and "wait, let's
think this through first." Choosing to just do it can seem to be the shortest path to the goal,
but it rarely is. It's an example of a Finger Puzzle.
- Remote Facilitation in Synchronous Contexts: II
- Facilitators of synchronous distributed meetings — meetings that occur in real time, via telephone
or video — encounter problems that facilitators of face-to-face meetings do not. Here's Part II
of a little catalog of those problems, and some suggestions for addressing them.
- Project Improvisation Fundamentals
- Project plans are useful — to a point. Every plan I've ever seen eventually has problems when
it contacts reality. At that point, we replan or improvise. But improvisation is an art form. Here's
Part I of a set of tips for mastering project improvisation.
- Personnel-Sensitive Risks: II
- Personnel-sensitive risks are risks that are difficult to discuss openly. Open discussion could infringe
on someone's privacy, or lead to hurt feelings, or to toxic politics or toxic conflict. If we can't
discuss them openly, how can we deal with them?
- How to Get Out of Firefighting Mode: I
- When new problems pop up one after the other, we describe our response as "firefighting."
We move from fire to fire, putting out flames. How can we end the madness?
Forthcoming issues of Point Lookout
- Coming April 25: Narcissistic Behavior at Work: VI
- Narcissistic behavior at work distorts decisions, disrupts relationships, and generates toxic conflict. These consequences limit the ability of the organization to achieve its goals. In this part of our series we examine the effects of exploiting others for personal ends. Available here and by RSS on April 25.
- And on May 2: Narcissistic Behavior at Work: VII
- Narcissistic behavior at work prevents trusting relationships from developing. It also disrupts existing relationships, and generates toxic conflict. One class of behaviors that's especially threatening to relationships is disregard for the feelings of others. In this part of our series we examine the effects of that disregard. Available here and by RSS on May 2.

- 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.
