Decision Analysis Cycle

The decision analysis (DA) cycle is the top-level procedure for carrying out a decision analysis. The traditional cycle consists of four phases:

  • basis development
  • determinisitic sensitivity analysis
  • probabilistic analysis
  • basis appraisal.

The diagram below depicts the Decision Analysis Cycle:

A revised form of the cycle consists of an attention-focusing method followed by a decision method, each of which is composed of three stages:

  • formulation
  • evaluation
  • appraisal.

Famous quotes containing the words decision, analysis and/or cycle:

    “I know my fate. One day my name will be tied to the memory of something monstrous—a crisis without equal on earth, the most profound collision of conscience, a decision invoked against everything that had previously been believed, demanded, sanctified. I am no man, I am dynamite!”
    —Friedrich Nietzsche (1844–1900)

    “The spider-mind acquires a faculty of memory, and, with it, a singular skill of analysis and synthesis, taking apart and putting together in different relations the meshes of its trap. Man had in the beginning no power of analysis or synthesis approaching that of the spider, or even of the honey-bee; but he had acute sensibility to the higher forces.”
    —Henry Brooks Adams (1838–1918)

    “Oh, life is a glorious cycle of song,
    A medley of extemporanea;
    And love is a thing that can never go wrong;
    And I am Marie of Roumania.”
    —Dorothy Parker (1893–1967)
