System Statuses- TECO

Hi All
Can any one please let me know what is System status technically completed (TECO).
Have read some notes regarding this, it says you need to set this status to WBS
which are completed from technical point of view. So I am not getting this term "technical point of view".
When you should use this status ?
Thanks & Regards
