Simplicity Model enough to fulfill the present needs and worry about the future needs when they appear. Be realistic when modeling! Agile Modeling May

9
**Feedback Only way to determine if the work we have done is correct.**

Ways to obtain feedback: Develop model as a team Review the model with the target audience Implement the model Acceptance testing Obtain feedback from the beginning of the project. Agile Modeling May

10
**Feedback Cost of fixing defects Probability of introducing defects**

Agile Modeling May

11
Courage In order to: Make decisions such as system architecture or development language. Recognize that one can make mistakes. To trust that one can overcome future problems in the future -> Enabling simplicity. Agile Modeling May

12
Humility In order to recognize that one that does not know everything and that one can learn from others. Agile Modeling May

**Agile Modeling Sessions**

Duration: At the beginning of a project: hours or daysMore than 2 or 3 days put your product at risk. During the construction of the projectBrainstorm Sessions: 10 to 20 minutes. Agile Modeling May

51
**Agile Modeling Sessions**

3 Key rules: Create several models in the same session with different artifacts. Just enough people. Just formal enough. Agile Modeling May

52
Brainstorm Sessions Stand-up meetings around a whiteboard or a table preferred. Focused on a single topic (a small chunk of requirements) Stop modeling once goal is fulfilled. Agile Modeling May
