We necessarily make assumptions about our lives, including our work, because assumptions simplify things. And usually, our assumptions are valid. But not always.
Two components of the U.S. Consumer Price Index for 1994-2010: Medical Care (in blue), and Food (in red). Even if you do pay attention to the consumer price index relative to your own compensation package, it can give you a distorted view of its impact on you personally, because your own spending patterns might not match the average of all components. For example, if you have a new and growing family, food might be more important than medical care, unless you have health problems in your young family, or an elderly and ill parent. When evaluating your compensation, you must take the effects of inflation into account. Data from the U.S Census Bureau.
A constancy assumption implies that what has been true in the past will be true in the future, or that what is true here, in this situation, is also true there, in the same situation. We tend to regard constancy assumptions as more factual when they've been valid for longer periods, or when they've been validated in more places. That is, the more examples we have of their validity, the more likely we are to regard them as facts, rather than assumptions.
And that's when we're at risk of making big mistakes. Constancy assumptions are usually subject to defects related to context. For example, when we apply the brakes on a bicycle, our experience is that the bicycle will slow and eventually stop. At least, this has happened so many times that we expect it will always happen. But on icy roads, or rainy days, or when the bicycle has just gone through a puddle, the brakes might not be so effective. Our constancy assumption might be violated.
Some constancy assumptions are more likely to be invalidated as the number of examples of validity increases. For example, when people are required to accept yet another year of inadequate pay raises, their tolerance is tested each year, but they generally accept paltry increases. Eventually, though, the level of pay falls far enough below their needs, or below what other employers offer, and their acquiescence ends. Those employees who are the most attractive to other employers then find employment elsewhere.
Here are some examples of constancy assumptions that are sometimes inappropriately regarded as facts.
- Productivity rates
- Estimating the person hours required to execute projects is a delicate art. We try to convert art into science by collecting and using experience data, but that data can be misleading. For example, when our workforce ages even by a few years, the demands of home life can change, and those changes affect productivity.
- Personal trustworthiness
- When personal circumstances change, people make different choices and change their alliances, We tend to regard constancy assumptions
as more factual when their pasts
are longer, or when they've been
validated in more placesnot because their values change, but because their goals and tactics do. Somebody you distrusted last year might be trustworthy this year, and vice versa.
- Supervisory relationships
- Cultivating a strong relationship with your supervisor is almost always worthwhile, but reorganization or a change of supervisor can nearly erase that investment overnight.
- The value of annual compensation
- In most national economies, inflation is slow but steady, and it erodes everyone's compensation. Other sources of compensation erosion are pay cuts, layoffs, and benefits reductions. Assuming that compensation is constant or increasing is probably risky. Save.
Perhaps the most widespread constancy assumption concerns the possibility or necessity of finding a new job. People tend to assume that their current positions will endure. They stay in their jobs, often unhappy and underpaid, rather than exploring opportunities elsewhere, until too late. Are you among their number? Top Next Issue

- The Fundamental Attribution Error
- When we try to understand the behavior of others, we often make a particularly human mistake. We tend to attribute too much to character and disposition and too little to situation and context. When we seek a better balance, we can adopt a more accepting view of events around us.
- Nine Project Management Fallacies: Part II
- Some of what we "know" about managing projects just isn't so. Identifying the fallacies of project management reduces risk and enhances your ability to complete projects successfully.
- An Emergency Toolkit
- You've just had some bad news at work, and you're angry or really upset. Maybe you feel like the target of a vicious insult or the victim of a serious injustice. You have work to do, and you want to respond, but you must first regain your composure. What can you do to calm down and start feeling better?
- Snares at Work
- Stuck in uncomfortable situations, we tend to think of ourselves as trapped. But sometimes it is our own actions that keep us stuck. Understanding how these traps work is the first step to learning how to deal with them.
- The Halo Effect
- The Halo Effect is a cognitive bias that causes our evaluation of people, concepts, or objects to be influenced by our perceptions of one attribute of those people, concepts, or objects. It can lead us to make significant errors of judgment.

- 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 an upcoming date for this program:
- Managing in Fluid Environments
- Most people now work in environments that can best be characterized as fluid, because they're subject to continual change. We never know whats coming next. In such environments, managing — teams, projects, groups, departments, or the enterprise — often entails moving from surprise to surprise while somehow staying almost on track. It's a nerve-wracking existence. This program provides numerous tools that help managers who work in fluid environments. Read more about this program. Here are some upcoming dates for this program:

- The Race to the South Pole: The Organizational Politics of Risk Management
- 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 risk management, its application to organizational efforts, and how workplace politics enters the mix. A fascinating and refreshing look at risk management from the vantage point of history and workplace politics. Read more about this program. Here's an upcoming date for this program:
- Team Development for Leaders
- Teams at work are often teams in name only — they're actually just groups. True teams are able to achieve much higher levels of performance than groups can. In this program, Rick Brenner shows team leads and team sponsors the techniques they need to form their groups into teams, and once they are teams, how to keep them there.
