  1. Portfolio Scenario

    Scenarios provide the ability to save different Resource Aligner constraint sets (e.g., budget limit, musts, must-nots, custom constraints, dependencies, funding pools, and groups).  You can then compare these scenarios in a Pareto Curve (see Effici...
  2. Redundant Judgments

    A minimum spanning set of judgments for a cluster of n elements consists of a set of n -1 judgments, in that every element can be "reached" from every other element.  It is necessary to have a spanning set of judgments in order to compute the pri...
  3. Spanning Set

    Expert Choice employs an algorithm to determine when a spanning set of judgments has been entered for a cluster of elements, at which point priorities can be derived.  A spanning set of judgments is such that every element can be "reached" from eve...

  6. Politics, Governance and Control

    The ability for AHP to aggregate (synthesize) and filter (assign roles) is important for several reasons. Governance and Roles Power and control are distributed in organizations in a wide variety of ways.  An effective decision process must r...
  7. Structuring

    In conformity with the second of the three AHP axioms originally proposed by Saaty, the elements of any cluster should be "homogeneous," meaning that they should differ in importance from one another by no more than an order of magnitude. This req...
  8. Validation exercises

    Brightness of Light Experiment Area Validation Experiment The relative areas of different geometric shapes (each within an order of magnitude) were derived from pairwise verbal judgments for shapes such as the following:  This experiment...
  9. Comparion Sample Templates

    Templates contain the structure of the model but do not contain participant information, data, or results.  You can use these templates to create new models.  You can also create your own templates from the workgroup models list from the drop-do...
  10. Simple tradeoffs

    Making decisions involves making tradeoffs  among objectives; this is a difficult and poorly understood aspect of decision making.  Decisions become difficult when they involve several competing objectives.  The greater the number of objectives, th...
