| The objective is to resolve the overarching issues which affect the design and development activity for the current |
| iteration. These are: |
| </p> |
| <ul> |
| <li> |
| To specify common mechanisms or patterns to be used. |
| </li> |
| <li> |
| To specify what use will be made of existing software assets and how they will integrate with the overall |
| solution. |
| </li> |
| <li> |
| To specify what new software needs to be developed. |
| </li> |
| <li> |
| To ensure that the appropriate hardware and software resources are specified to support the development and |
| testing of the solution. |
| </li> |
| <li> |
| To ensure that the architecture is useful to and used by the project team. |
| </li> |
| </ul> |
| <p> |

| decisions in the <a class="elementLink" |
