Effectiveness and Efficiency – there is still a bit of confusion about this pair of terms. Sometimes, they are used interchangeably. The distinction seems to be a bit blurring. I guess one part of the problem is that these terms sound fairly similar. Another reason is that effectiveness and efficiency often come together in a common context. An activity may be effective and efficient, effective or efficient, or neither of the two.
