Engraçado, se pensarmos bem tudo o que está escrito abaixo não é nada além do óbvio. Mas minha experiência diz que num é bem assim.

The Core Commitments of Scrum:

1. I commit to:

Engage when present, and to know and disclose what I want. what I think, and what I feel;

To always seek effective help;

To decline to offer and refuse to accept incoherent emotional transmissions.

When I have or hear a better idea than the currently prevailing idea, I will immediately either
propose it for decisive acceptance or rejection, and/or explicitly seek its improvement.

I will personally support the best idea regardless of its source, however much I hope an even better idea may later arise, and when I have no superior alternative idea

2. I will seek to perceive more than I seek to be perceived.

3. I will use teams, especially when undertaking difficult tasks.

4. I will speak always and only when I believe it will improve the general results/effort ratio.

5. I will offer and accept only rational, results-oriented behavior and communication.

6. I will disengage from less productive situations when I cannot keep these commitments, and
when it is more important that I engage elsewhere.

7. I will do now what must be done eventually and can effectively be done now.

8. I will seek to move forward toward a particular goal, by biasing my behavior toward action.

9. I will use the Core Protocols (or better) when applicable. I will offer and accept timely and proper use of the Protocol Check protocol without prejudice.

10. I will neither harm—nor tolerate the harming of—anyone for his or her fidelity to these commitments.

11. I will never do anything dumb on purpose.
