Here is a website with many kinds of outlines for problem solving techniques. Some take a little bit of clicking around, and some require a paid subscription to the site to access.

I can't remember if I posted this here before or not but here it is anyway.
Thanks, Apathy. Having access to something like that would probably have been a help when I was running a business, and I expect others here would find it useful. :)
Yeah it seemed like it was catered to problem solving within management instead of every day things, but I used it for everyday things as well.
