When we plan projects, we estimate the duration and cost of something we've never done before. Since projects are inherently risky, our chances of estimating correctly are small. Quantum Management tells us how to think about cost and schedule in new ways.
Allison stood at the front of the room, next to the LCD, wanting desperately not to be there, as the marketing VP demanded, "Don't give me 'March 15 to April 29.' I want to know when exactly this thing will ship!" Trouble was, she couldn't say exactly — things were too unpredictable, and he just didn't seem to get it. So she caved: "OK, we'll have it by April 29."
"Oh, no you don't," he replied. "We'll take the middle of your range. What's that," he turned to the director beside him, "April 5? April 5. That's it. Next case!"
So that's what they did, and Allison's team finally shipped on April 26, three weeks late. A black eye for Allison, for the team, and for the engineering group. What was going on here?
Problem-solving organizations do two kinds of work — Operations and Projects. Operations work is ongoing effort repeated often — things like manufacturing, "routine" administration, and infrastructure operations. Project work is one-of-a-kind — new product development, relocation, and reorganization. Operations are repeatable and less risky. Projects are unique and riskier. Although we usually manage Projects as if they were Operations, Projects must be managed differently. Quantum Physics can help us understand why.
In Quantum Physics some things are inherently unknowable. For example, the more precisely we know the position of a moving body, the less precisely we can know its velocity, and vice versa. Classical Physics had no such restriction.
Not both.There is an analogy in management. If we want to know cost and schedule precisely, we must reduce innovation, because innovation creates risk. If we accept risk, we must settle for less predictability of cost and schedule. Quantum Management says that you can't have precision in the context of risk.
Since our management practices originated in operations-oriented organizations, our managers don't like to hear that "we expect completion within 4-6 months." They often demand "drop dead" dates. This is Classical Management, and it's analogous to Classical Physics.
You can move your organization toward Quantum Management. As a manager:
- Ask not "When will it be ready?" Ask, "When is there a 95% probability that it will be ready?"
- Reward project managers who make estimates in 95% confidence bands.
- Require that Corporate Finance manage risk across a portfolio of projects, rather than by demanding precision at the individual project level.
As a project manager:
- Estimate best and worst case as 95% confidence bands.
- When people ask you for a drop-dead date, try to educate them in Quantum Management. You might fail — or you might make some progress.
Whenever you're at the front of the room being hammered for a drop-dead date, remember that accepting one doesn't change the laws of Quantum Management. Top Next Issue

- 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.
- An Agenda for Agendas
- Most of us believe that the foundation of a well-run meeting is a well-formed agenda. What makes a "well-formed" agenda? How can we write and manage agendas to make meetings successful?
- Dubious Dealings
- Negotiating contracts with outsourcing suppliers can present ethical dilemmas, even when we try to be as fair as possible. The negotiation itself can present conflicts of interest. What are those conflicts?
- 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.
- Durable Agreements
- People at work often make agreements in which they commit to cooperate — to share resources, to assist each other, or not to harm each other. Some agreements work. Some don't. What makes agreements durable?

- The Race to the South Pole: Ten Lessons for Project Managers
- 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 project managers, the story is fascinating. Lessons abound. Read more about this program. Here's an upcoming date for this program:
