WHERE THERE'S PEOPLE, THERE'ES VARIABILITY
One of the biggest barriers to hiring accuracy is human complacency.
Put simply, some people involved in hiring don't think the hiring decision actually matters that much.
For those cases, remember Principle 11:
"Where There's People, There's Variability."
If everyone was the same, it wouldn't matter who you hired. You wouldn't need a screening process.
Who you hire matters because people are different.
Their attributes vary (a lot)...
And the results they produce vary (a lot) as well.
This often follows the scientific phenomena known as the "The Pareto Principle":
-For a given event, ~20% of the inputs will often produce ~80% of the outputs.
In hiring, this means 20% of hires will produce 80% of the total value.
And conversely, 20% of hires will produce 80% of the total losses.
This is true for a given position, or across an entire company.
And it's why having a process that helps you accurately identify and select 'great hires' and avoid 'bad hires' is so crucial.
