Earlier, I wrote a post about some lessons learned in leading a group data collection project. I applied it to being a supervisor and said if you trust your employees to do a good job and get out of their way, they will do a good job. I think that is still true, but it didn’t turn out as planned in my group. I’ve learned that some of the group members entered the data incorrectly causing much of it to be unusable. That’s unfortunate for the data analysis, but for me, it’s another lesson learned: you can only expect someone to do a good job if they’ve been properly trained. You must properly train someone to do a task before turning them loose to do it.
