They use decision milestones to anticipate outcomes, risk management to prevent disasters and sequential iteration to make sure everyone is making the desired product, yet the project still ends up with an overrun schedule, overflowing budget and compromised specifications. Or it just dies.

To find out why, we studied 16 projects in areas including personal-computer development, telecommunications, Internet startups, pharmaceutical development, iron-ore processing, airship development and building construction. Interviews with team members and scrutiny of project documentation over five years showed managers consistently failing to recognize that there are different types of uncertainty, each of which requires a different management approach. The lack of awareness is understandable, given that the commonly accepted definition of a project (“a unique interrelated set of tasks with a beginning, an end and a well-defined outcome”) assumes that everyone can identify the tasks at the outset, provide contingency alternatives and keep to the same overall project vision throughout.1 Those are fair assumptions for routine or well-understood projects, but not for novel or breakthrough initiatives, which require companies to rethink the traditional definition of a project — and the ways to manage it.

A more forward-thinking approach is uncertainty-based management, which derives planning, monitoring... To read the complete article, login or sign-up using the form below.
