The Hawthorne Effect
In the 1920-30s, experiments were conducted in the Hawthorne Works Electric Company to determine if changing the lighting would affect worker productivity.
When the lights were turned up, productivity increased. When the lights were turned down... it also increased. But only while the experiment was happening. Once the research was complete, productivity returned to the previous levels.
The Hawthorne Effect was defined as a change in behaviour that was due to an awareness of being observed. It made researchers aware of the impact they had in an experiment - something that they are obviously keen to avoid.
It also signalled that a higher level of attention could have positive effects. Making these workers feel special by including them in a study, being interested in their work seemed to make a difference.
Pay attention to the work your people are doing. Make them feel valued. Do it regularly.
Is there ONE THING you could do to make those how work with you feel a bit special?
