Matrix-Based Techniques

These techniques involve the construction and filling-in of a 2-dimensional matrix (grid, table). Useful examples are:

  • Concepts v Properties (attributes and values)
  • Problems v Solutions
  • Hypotheses v Diagnostic techniques
  • Tasks v Resources

The elements within the matrix can contain:

  • Symbols (ticks, crosses, question marks
  • Colours
  • Numbers
  • Text

The use of frames (see knowledge models) can also be adopted, although this would typically be used for validating previously acquired knowledge rather than for eliciting knowledge from scratch.

Timelines (see knowledge models) can also be used to acquire time-based knowledge.

The Matrix Tool in PCPACK allows the creation of most types of matrix.
