Decision Analysis

Decision analysis is one of the 16 required techniques required for an effective business analyst. Decision analysis allows us to select a decision from a set of possible decision substitutions when ambiguities regarding the future exist. Stakeholders use decision analysis to examine a problem and make decisions in unreliable conditions.
The business analyst uses decision analysis to analyse different results in undefined or complicated circumstances.
Decisions are often challenging to analyse in the following situations:
• The problem is poorly described.
• The stakeholders don’t recognise why the primary action was taken.
• The environmental factors impelling the result are not fully comprehended.
• The conclusions of diverse circumstances are not understood by the stakeholders and so those results cannot be associated against one another.
There are various decision analysis methods and the chosen style varies on the degree of improbability, risk, value of information, and assessment criteria.
