Unknown unknowns pose a tremendous challenge as they are essentially to blame for many of the unwelcome surprises that pop up to derail projects. However, many, perhaps even most, of these so-called unknown unknowns were actually knowable in advance, if project managers had merely looked in the right places.
For example, investigations following major catastrophes (such as space shuttle disasters, train derailments, and terrorist attacks), and project cost and schedule overruns, commonly identify instances where a key bit of knowledge was in fact known by someone working on that project—but failed to be communicated to the project’s top decision makers. In other cases, unknown unknowns emerge from unforeseen interactions among known elements of complex systems, such as product components, process activities, or software systems.
With the right mindset and toolset, we can shine a light into the right holes to uncover the uncertainties that could affect a project’s success.
