    Study Notes

    • The systems sciences, including General Systems Theory, Cybernetics, and Complexity Theory, aim to provide foundational concepts for a meta-discipline called Systems Engineering (SE).
    • SE, informed by systems science, can enhance its theory and practice, making it applicable to complex systems.
    • Systems Thinking is a key enabler of SE, one of its core competencies, and a framework for understanding complex situations.
    • Systems thinking consists of four universal rules: Distinctions, Systems, Relationships, and Perspectives.
    • SE practitioners need to possess the knowledge and skills for holistic analysis and systemic intervention.
    • Jackson and Keys (1984) offered an initial classification of systems methodologies called Systems of Systems Methodologies (SOSM) based on their strengths in addressing complexity and stakeholder viewpoints.
    • Jackson updated SOSM (2019) to reflect developments in Complexity Theory and this approach is called Critical Systems Thinking (CST).
    • CST is a multi-perspectival, multi-methodological, and multi-method approach that uses different systems approaches based on their strengths and weaknesses.
    • Systems methodologies translate hypotheses about problem situations into practical action and include System Dynamics, the Viable System Model, Soft Systems Methodology, and Critical Systems Heuristics.
    • The weighting of each system approach in a hybrid solution is tailored based on technical, organizational, cultural, and political factors within the organization.
