More often than we'd like, our projects are late or over budget. Or we find that the problem we've tackled is much more difficult than we thought. We aren't stupid (though some might argue otherwise), and we aren't trying to gild lilies our build empires (though some might argue with that, too). Still, these things happen with such regularity that there must be an explanation.
Part of the answer might be that much of the work we do is of a nature that our minds have difficulty comprehending. One property that gives us trouble is nonlinearity.
For example, consider the issue raised by Fred Brooks in The Mythical Man-Month. If three people can complete a task in six months, many would suppose that nine people can complete it in two months. We now understand that this belief is unfounded, and that our expectations are rarely met.
To understand why, let's begin by defining linear work. Work is linear when the outcomes are directly traceable from, and scale with, inputs. When work is linear, we can successfully plan the outcomes before we begin, because we can predict the course of the effort. To make linear tasks go faster, we can divide them into parts that we execute in parallel, without risking complication.
For example, two identical, independent assembly lines can produce output at double the rate of one single line, assuming that their supply and delivery chains are also independent. A manufacturing process implemented as independent assembly lines is a linear process.
But In a system that doesn't
obey superposition, the whole
can be different from
the sum of its partsnonlinear work doesn't follow this pattern. Although most of the work we do in project-oriented organizations behaves linearly in response to small adjustments, the nonlinearities dominate when we scale those adjustments to a size where we expect to derive large benefits. One attribute of nonlinear work that explains this phenomenon is its failure to obey superposition.
In a system that doesn't obey superposition, the whole can be different from the sum of its parts. In such cases, as we apply more and more resources, the yield per unit of resource can decline. In the case of Brooks's mythical man-month, this can happen because of increased need for management and communication, and increased difficulty in scheduling.
But superposition can fail for a wide variety of reasons. For example, when we decompose a problem into parts, and try to work on the parts separately, one task team might require — solely for scheduling purposes — that another task team take an approach that is less effective than it would have taken if it were free to act independently. We can easily generate numerous examples like this that show failures of superposition that confound our expectations.

- Are You Changing Tactics or Moving the Goal Posts?
- When we make a mid-course correction in a project, we're usually responding to a newly uncovered difficulty
that requires a change in tactics. Sometimes, we can't resist the temptation to change the goals of
the project at the same time. And that can be a big mistake.
- Nepotism, Patronage, Vendettas, and Workplace Espionage
- Normally, you terminate or reassign team members who actually inhibit progress. Here are some
helpful insights and tactics to use when termination or reassignment is impossible.
- Guidelines for Sharing "Resources"
- Often, team members belong to several different teams. The leaders of teams whose members have divided
responsibilities must sometimes contend with each other for the efforts and energies of the people they
share. Here are some suggestions for sharing people effectively.
- Down in the Weeds: II
- To be "down in the weeds," in one of its senses, is to be lost in discussion at a level of
detail inappropriate to the current situation. Here's Part II of our exploration of methods for dealing
with this frustrating pattern so common in group discussions.
- 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 October 23: 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. Available here and by RSS on October 23.
- And on October 30: Power Distance and Risk
- Managing or responding to project risks is much easier when team culture encourages people to report problems and question any plans they have reason to doubt. Here are five examples that show how such encouragement helps to manage risk. Available here and by RSS on October 30.

- The Race to the South Pole: Lessons in Leadership
On 14 December 1911, four men led by Roald Amundsen reached the South Pole. Thirty-five days later, Robert F. Scott and four others followed. Amundsen had won the race to the pole. Amundsen's party returned to base on 26 January 1912. Scott's party perished. As historical drama, why this happened is interesting enough. But to organizational leaders, business analysts, project sponsors, and project managers, the story is fascinating. We'll use the history of this event to explore lessons in leadership and its application to organizational efforts. A fascinating and refreshing look at leadership from the vantage point of history.

- 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.
