 |
| The architect should perform this task&nbsp;through collaboration with the whole&nbsp;team to promote consensus and a
 |
| 
 |
| common understanding of the overall solution. The architect should be working to coordinate and guide the technical
 |
| 
 |
| activities of the team, rather than seeking to do all the work alone.&nbsp;The architect should place emphasis&nbsp;on

| 
 |
| involving&nbsp;the developer(s) throughout this task.
