The 3 E's are: economy, effectiveness and efficiency.

Is anybody going to contribute to this blog.....what ar the three E's we referred to in class! WHo is ging to send the first post!?

I can see that quite a few students have entered the blog...but none have written a post!!!

May we at least start by reminding ourselves what the three E's are!!
May someone answer this question......first....and we will proceed from there!
