Why Time Span is Important

From the Ask Tom mailbag –

Why is Time Span important? I don’t see how the length of time it takes, to complete a task makes a difference in writing the role description.

Calibrating the level of work in the role description is absolutely critical for the manager to gain insight into the decision making and problem solving required for success in the role. If the hiring manager cannot determine the level of decision making and problem solving, the successful search for a candidate will mostly be based on luck.

Intuitively, we can agree that some problems are more complex than other problems. Intuitively, we can agree that some decisions are more complex than other decisions. But, intuitive understanding does not help us measure that complexity.

And I am not talking about detailed complexity. Engineers love detailed complexity. They write computer software to handle all the detail in scalable databases. That is not the complexity I am talking about.

The complexity I am talking about, is the complexity created by the uncertainty of the future, the complexity created by the ambiguity of the future. That complexity can be measured by identifying the target completion time (Time Span).

Do you remember Murphy? Murphy has a law. Anything that can go wrong, will go wrong. How long do we give Murphy to play? That is Time Span.

The Time Span of a problem or the Time Span of a decision will give the hiring manager insight into the talent (capability of the candidate) required to be effective in the role.

  • Short term problems can be solved through trial and error.
  • Medium term problems may require experience (documented experience).
  • Long term problems (problems we have never solved before) may require root-cause or comparative analysis.

The Time Span of the problem will indicate the method (and capability) required to solve it.

Remember the BP oil spill in the Gulf of Mexico? The Time Span of the problem at hand was short. The problem required an emergency solution. We watched on television, in real time, as engineers cobbled together trial and error solutions. We did not need a sophisticated well thought out solution. There was no time for longitudinal studies of hydraulic pressures in geological fissures. We just needed a mechanical wrench to choke off a hole in an underwater pipe.

But longer term, when drilling rigs are designed, to simultaneously get to the oil AND safely protect the operating crew AND protect the long term environmental impact, well, that solution will require a bit more than choking off a hole in a pipe.

The Time Span of a problem or the Time Span of a decision gives us insight into the talent required to be effective in the solution. And the person selected out of the candidate pool makes all the difference.

The solution is seldom a matter of WHAT, more often a matter of WHO.
