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

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.

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.

50. Agile Modeling Sessions
Duration:
At the beginning of a project: hours or daysMore than 2 or 3 days put your product at risk.
During the construction of the projectBrainstorm 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.

54. Applying Agile Modeling: XP
Exploration Phase
XP concentrates on System Metaphores, but that does
not mean that other diagrams can not be created
Agile Modeling
May

55. Applying Agile Modeling: XP
Planning Phase
Task cards
Sketches of logic of task
User Interface
Team and customers agree on date in which the
smallest implementation will be done-brainstorm of tasks
Agile Modeling
May

56. Applying Agile Modeling: XP
Iteration to release Phase
Stand up meetings: developers discuss problems around a whiteboard,
drawing sketches to enhance communicationModeling!
Agile Modeling

57. Applying Agile Modeling: XP
Productionizing Phase
AM done when errors are discovering and Modeling has to be done to work through the problem.

Agile Modeling can be used in a software process in order to enhance modeling.
In order to say you are Agile Modeling you need to follow all of the Principles and Practices of Agile Modeling.
