A few years ago at work, we were required to participate in High Performance Training. It took a few afternoons a week of our time for several months (perhaps we were the remedial group) and there was a general sense of discomfort among my team over the whole process. I disliked it for different reasons which I'll perhaps get into later.
Apart from doing all sorts of team exercises and activities designed to pull us apart and put us back together, there were some interesting things we learned. We were able to identify and streamline processes that had previously seemed cumbersome but had 'always been done this way'. An example of how this occurs might work along these lines: You think you have a secret technique for cooking the best roasts and it's been handed down through your family. Cut the roast in half and cook it in two separate pans, it works every time and makes the most delicious roasts. You do this because that's the way Grandma always did it and your Mom always did it and they were excellent cooks. Then you ask one day how Grandma discovered her little secret and you find out she cut the roasts in half because she didn't own a large enough roasting pan.
For years there was a red bin near our fax machine at work and the staff member in charge of retrieving, sorting and delivering them put up a paper notice saying Please leave faxes in order and in the red bin. At some point, the bin was changed to an orange one and there was a new staff person assigned to the fax area. The paper notice got replaced with a nice new one that said Please leave faxes in order and in the red bin. It took a long time for someone to scratch out the word red and replace it with orange. This week, I noticed someone had scratched out orange and replaced it with hue of pumpkin.
I'm looking forward to seeing a new sign and how far back or forward we'll travel over this.
