Objective Analysis - Advantages and Limitations

  • The objective tree allows a rigorous development of explicit and comprehensive objectives. This helps the design or implementation of a project to achieve the desired ends
  • As the objectives are made explicit, the diagram is useful to communicate the relationship between objectives to other decision makers and interested groups
  • Objective trees may incorporate both quantitative and qualitative objectives. Qualitative objectives may be expressed at a lower level of the hierarchy.
  • The process of developing the tree often indicates interlinking or related objectives which might not otherwise be considered.
  • No single objective tree is valid for a particular project. Each person will construct an objective tree in a different manner. There is an inherent uncertainty and ambiguity in specifying objectives.
  • The stated and the actual objectives of personnel in an organisation may differ significantly. Determining actual objectives is a difficult (if not impossible) task.
  • There may be confusion over means versus ends. An objective tree structures the statement of goals (or ends) by identifying sub-objectives (means) to their attainment.
