Perspective taking reveals aspects of complex systems.  This is a natural starting point for systemic investigations, since one can only see aspects of complex systems and never the entire system. The graph shows that investigating these aspects to get a deeper understanding requires  examining them through appropriate interpretive concepts of which systems thinking has many to offer. However, not all systems thinking methodologies concentrate on the investigation the dynamic feedback mechanism of systems. Systems thinking methodologies that ignore feedback mechanisms  do  not possess  a suitable contextual vocabulary for their investigation, and as a result do not offer any advantage over other  investigative methodologies when it comes to investigating the dynamic systems that are traditionally the target of systemic investigation.
