Figure 2
The model contains a horizontal line that divides the diagram into two vertical sections. The top section is labeled “The real world (events unfolding through time)”, and the bottom section is labeled “Systems thinking about the real world”. The model consists of seven text boxes, five positioned in the top section and two positioned in the bottom section. In the top section, from left to right, the first text box labeled “First” contains the text “What is the problem?” A downward arrow connects it to the second text box labeled “Second”, which contains the text “Structure the problem situation”. From the second text box, a downward arrow extends to the third text box in the bottom section labeled “Third”, which reads “Identify human activity systems named in root definition using CATWOE elements”. A rightward arrow from the text box “Third” connects to the fourth text box labeled “Fourth”, which reads “Conceptualise models of human activity systems named in the root definitions”. An upward arrow from the text box “Fourth” connects to the fifth text box in the top section labeled “Fifth”, which reads “Compare models with perceptions in the problem situation”. From the fifth text box, a rightward arrow connects to the sixth text box labeled “Sixth”, containing the text “Identify feasible desirable changes”. A rightward arrow from the sixth text box connects to the seventh text box labeled “Seventh”, containing the text “Take action in the problem situation”.SSM model
