3.3 Commitment

Development team members must be committed to success and be willing to create realistic goals and stick to them. Perceiving individual achievements as secondary, every scrum role commits to the success of the team, thus, creating an environment of trust, productive problem solving, and high team standards. The keys to this are as follows:

The product owner demonstrates commitment by making the best decisions to optimize the value of the product, not simply trying to please every stakeholder.
The scrum master demonstrates commitment by upholding the scrum framework, which means we do not extend the sprint or other time-boxes under pressure to get to Done.
The scrum master also demonstrates commitment by removing impediments that the development team cannot resolve themselves, rather than tolerating the status quo in the organization.
The development team demonstrates commitment by creating an increment that meets their definition of Done and not something that is almost done.
