Hi Dash -,
This is my own view:
You should have an approval task before awarding only if it is guided by your company policy. The reason behind the same is that the approval tasks in general create a bottleneck as mild disadvantage v/s the excellent system control it has to offer.
To strike a perfect balance between the system control and avoiding bottlenecks is to create awarding scenario's at the template level and let the sourcing agent have rest of the control within this guided approach.
Cheers!!
