Staffing or specifically sourcing is like hitting in baseball. To quote the character ‘Jack Elliot” from the movie “Mr. Baseball”, “Hitting is like the tide, there is high tide and there is low tide and then there is high tide again”. This analogy works well for staffing. Think about it. One minute you are finding anything and everyone you want, next you are struggling, then eventually you are back to finding anyone.
This high tide/low tide phenomenon has more to deal with our own brains then an actual event. Basically after a while of looking for the same thing our brains kind of run out, or have a low tide, of ideas of different places and ways to find what we are looking for. Like with a hitter who is struggling sometimes we need a break, a change of pace, a day off, a soft reboot, and all of a sudden we are brimming with ideas and its high tide again.
The idea here being when you run out of ideas, when it is low tide, just take some time, take a break, do something else for a little while, reboot your brain and high tide will be back again.
