Decision matrices are awesome. I first learned about them in my econ class in high school. Basically, they are a chart that helps you make a decision between two or more options. I talked about them in a couple of my undergrad classes as a method for making decisions. No one knew what I was talking about but my Econ professor got REALLY excited and asked me all about them. I think everyone else just thought I was a nerd. I don't care, they're very useful.
Here is my decision matrix about toaster ovens and stand mixers:
|Amount I'll Use It||Time Saved||Electricity Saved||Versatility||Storage Space||Taste of Results||Total|
|Stand Mixer||1||1||1||2||2||1||8 |
You put your choices on one side and all the factors on the other, basically, then decide which option "wins" that category. Add up the numbers to get the total and you have what your decision should be. Here, I have decided that I should get the toaster oven. I didn't add some other important factors like "ability to cook pizza" or "ability to cook two cookies at a time" but I thought about it.
