| This task focuses on defining a candidate architecture that will guide the development, testing, and |
| operation of the system. It relies on gathering experience gained in similar systems or problem domains to constrain |
| and focus the architecture so that effort is not wasted in re-inventing architecture. |

| This task is most beneficial when developing new and unprecedented systems. In systems where there is already a |
| well-defined architecture, this task might be omitted, or performed quickly as a review of the existing |
| architecture. |
| </p> |
| <p> |
| It is critical that this task is performed collaboratively with active involvement of other team members and project |
| stakeholders so that consensus and common understanding is reached. It is particularly vital for the architect to |
| involve the developer(s) throughout this task. The architecture effort is about providing leadership and |
| coordination of the technical work rather than putting in a solo performance. |
