Decision matrixes

Assessment results obtained by questionnaires and scripted metrics can be mapped to decision matrixes. Assessment administrators can view and create these dynamically updated graphs, which make it possible to compare assessable records by category. Decision matrixes display data from a trailing twelve month (TTM) period.

The decision matrix page has these components:

Component Description
Options
Filter Select the subset of assessable records you want to view. The filter options available vary by metric type, based on the Filter field and Filter condition field settings for each type.
Decision matrix components
Scale Select the scale for the decision matrix. The greater the scale, the larger the decision matrix appears.
Decision matrix
X- and Y-axes Each axis represents one or more metric categories. If multiple categories are used for an axis, their respective weights determine the positioning of the plotted items.
Plotted items The labeled points you see on a decision matrix, called plotted items, represent averages of category result data for assessable records. Point to a plotted item label to view a rating summary for that assessable record. Click a plotted item label to view the scorecard for the assessable record.

Plotted item rating summaries:

If you point to a plotted item label on a decision matrix, a rating summary appears. The summary displays the assessable record's average ratings for each axis. If an axis represents one metric category, the ratings are calculated averages from results for that category. If an axis represents multiple categories, the ratings are calculated averages from weighted results for all of the categories.

The summary shows:
  • Current rating
  • Difference between the current rating and the rating from the previous year
  • Ratings from each previous year, going back three years
