Find greater success by embracing ‘soft’ deadlines

New research on project management finds that embracing uncertainty around deadlines can lead to greater success.

The work offers a way to peek under the hood of deadlines, map out their uncertainty, and fold it into a project management system.

“Our society tends to think of deadlines as less flexible than other aspects of a project, but in reality, that’s often not the case…”

“Our society tends to think of deadlines as less flexible than other aspects of a project, but in reality, that’s often not the case,” says Tom Logan, a doctoral student in industrial and operations engineering at the University of Michigan. “When we recognize that, it enables us to do some really novel things.”

Success rate

Logan worked on the project with Robert Bordley, professor of practice and program director in Integrative Systems + Design at the University of Michigan College of Engineering.

In a series of experiments testing the team’s technique, it improved the success rate of projects by up to 40 percent. That improved success rate can manifest itself in a variety of ways, including more timely completion, projects that better fit the original requirements, and improved profitability.

“A deadline is just another stakeholder requirement and we all know that stakeholder requirements hold a certain amount of uncertainty,” Bordley says. “We can’t eliminate that uncertainty, but we can often quantify it. And I’ve found that the value of doing that is very big.”

The solution, which appears in the European Journal of Operational Research, is to work with stakeholders to understand the uncertainty and work it into the project as an active, manageable variable.

How to work with stakeholders

The hard part comes first—managers should ask for more than just the optimistic and pessimistic completion dates that are part of Project Evaluation and Review Technique, the statistical tool that underpins modern project management. This requires an honest sit-down with stakeholders and some digging to learn the reasoning behind those dates.

“Stakeholders are always dealing with a complex set of uncertainties, but they are rarely shared with project managers. The goal is to bring the two worlds closer together and incorporate the knowledge that’s uncovered into the management process,” Bordley says.

“I like to ask stakeholders to think of a situation that would cause a deadline to get pushed forward by a month, for example. Tell me about that situation, estimate how likely it is to happen. Focus on the extremes. That way, you end up with optimistic and pessimistic deadlines that are more than just numbers.”

Find your bull’s-eye

With optimistic and pessimistic deadlines in hand, the next step is to indicate the uncertainty of the deadline within the project management system.

To do this, Bordley says, add an additional, virtual activity to a project. The activity begins on the optimistic completion date and ends on the pessimistic completion date, creating a virtual bull’s-eye for on-time completion. As long as the project finishes between the optimistic and pessimistic dates, it’s considered on time. The more uncertainty in the deadline, the larger the bull’s-eye.

The manager can then make decisions based on the uncertainty of the deadline. A less certain deadline means a larger target and more flexibility to focus resources on other project requirements that are more certain.

The virtual activity can also be adjusted as the project progresses—shrinking as the deadline firms up or growing as uncertainty mounts. Either way, it gives the manager a running forecast of deadline uncertainty and the ability to plan accordingly.

“This technique can save a manager from spending a lot of time and resources on a deadline that might not matter much in the end,” Bordley says. “If it’s soft, the manager can quickly see that it’s soft and focus resources on other requirements that are less likely to change.”

To test the effectiveness of the modification, the team built a computer model that cycled through 1,000 simulated projects. First, they applied a traditional PERT project management model that ignores deadline uncertainty, then they applied their modified model that recognizes deadline uncertainty and adjusts resources as needed.

Bordley and Logan devised the strategy along with Jeffrey Keisler, a professor at the University of Massachusetts-Boston.
