This chapter emphasizes that not all constraints are desirable in system design. What should be the main focus instead?

[dvberkel]

1. Encourage complex interactions
2. Constrain shared knowledge
3. Enable desired interactions
4. Answer 2 and 3 are correct

[dvberkel]

Since complex interactions are neither clear nor predictable, page 37, is should certainly not be encouraged.

In almost, but not quite, the same vain option 3 is correct. If you do not enable desired interactions, what are we even doing.

Furthermore, by contraining shared knowledge, as demonstrated in the connecting coupling and complexity example, a system will become less complex.

So the answer should be option 4; Answers 2 and 3 are correct.
