As stated earlier, all CASs operate on simple and minimal rules. For an enterprise, this means setting appropriate boundaries and keeping the rules simple and minimal. It also means letting the people, and networks of people, interact among themselves and with the environment to organize through an iterative process of creative exploration and selective destruction. Agility is most effective when the people who are closest to the environment have the space and freedom to interact with the environment as they deem appropriate and make the necessary modifications in the system. For example, an organization that is recognized for successfully transforming to Agile has only two rules for the teams: iteration length should be two weeks and the shared electronic tool should be updated with all relevant data on a real-time basis.
