สรุป	A Rich Picture is a free-form, annotated drawing used in the early exploratory stage of Soft Systems Methodology to represent the full complexity of a problematic situation. Developed by Peter Checkland at Lancaster University, it captures people, roles, concerns, processes, conflicts, and environmental factors in a single visual canvas. It is used primarily by systems analysts, organizational consultants, and action researchers who need to surface multiple stakeholder perspectives before imposing any formal structure on a messy, ill-defined problem.	Strategic Options Development and Analysis (SODA) is a facilitated, qualitative method for structuring complex organisational problems. Developed by Colin Eden in 1988, it uses cognitive maps — directed graphs of causal constructs — to capture and integrate the subjective views of multiple stakeholders. SODA is most valuable when decision makers face ill-defined, wicked problems where shared understanding must be built before any quantitative analysis can begin.	Soft Systems Methodology (SSM) is an interpretive, action-research approach for structuring and managing complex, ill-defined ('soft') problem situations involving human activity. Developed by Peter Checkland at Lancaster University throughout the 1970s and formally presented in 1981, SSM guides practitioners through iterative cycles of inquiry that move from an unstructured problem situation to purposeful action through structured learning rather than optimization.
