The application of System theory is called Business Systems Analysis.

One of the major tools of systems analysis is systems thinking. Basically, systems thinking is a way of helping a person to view systems from a broad perspective that includes seeing overall structures, patterns and cycles in systems, rather than seeing only specific events in the system. This broad view can help one to quickly identify the real causes of issues in organizations and know just where to work to address them.

Apply systems thinking to the analysis of a HRIS system and Project Management system. Conduct research on  HRIS

and Project Management systems and identify the objects, attributes, relations, and the environment in which the systems exists (e.g. type of industry, organization, etc.)
