2.4 The DA process

• The aim of the decision analysis (DA) process is to provide a structured way to think about decisions and develop and support subjective judgements that are critical for good decisions.
  
  
• As shown in Figure 1.4.1, DA processes typically involve four main phases.

• The processes are often large and iterative. For example, problem structuring, gathering of relevant information and the modelling of the DM's preferences often requires a considerable amount of work.
  
  
• The DM's perceptions of the problem as well as preferences for outcomes not considered before may change and develop during the process.
