You can think of these as like a set of playing cards that can be played when arguing in support of a program or organization's effectiveness.

If some cards are strong then you don't have to worry so much about playing your other cards.

Six of the seven outcomes system building-blocks can be seen as six types of evidence that can be offered that a program works (building-blocks one to six).

However, if some of your major cards are weak, you can compensate for this by playing a good mix of cards from all of the possible six measurement-related building-blocks.
