  14. Summary * Characterizing geospatial decision problems in terms of two basic dimensions, ranging from simple to complex, then from content to context. Solving complex decision problems motivates the use of GIS. More complex decision problems are likely to require more complex workflows. * A general assessment level provides insight an at overview level, focusing on convening, process, and outcomes of the decision situation. * In slightly more detail is an assessment by phase to describe the overview categories, but for each of the phases involved. * The third level, a construct assessment by phase, details constructs for each of the phases. The fourth level, a construct–aspect assessment by phase, details aspects of all constructs by phase in a decision problem.
