Waypoint Placement

What is the logic behind where waypoints are situated? Obviously some line up with approaches, and I assume some relate to geography, but others I do not understand. For example, why would this cluster be created to the left of runway 17, and not one dead center?;

They’re mostly placed according to real life specifications.

Yes, I am asking about real life. I’m assuming IF is representative of real life here (although I have not tried to confirm), so my question is in real life, why?

Nowadays waypoints compose airways (invisible highways in the sky) and have no logical relation to their geographical location.
They are used for flight planning, but mostly for the facilitation of air traffic control.
