Tool description

First introudced by T. L. Saaty (1988), prioritization matrices are used to prioritize among projects, issues, or options on the basis of team-established, weighted criteria. Three variations of matrix construction are used: (A) the full analytical criteria method, (B) the consensus criteria method, and (C) the combination interrelationship digraph/matrix method. Variation (C), the combination method, is used when strongly related options must be reduced to one or two.

Typical application

To apply team consensus criteria to select and decide on further action.

To prioritize among activities, issues, or options based on weighted criteria.

To select and prioritize recommended change options.

To allocate limited resoures to the most important option.

Problem-solving phase

→	Select and define problem or opportunity
	Identify and analyze causes or potential change
	Develop and plan possible solutions or change
→	Implement and evaluate solution or change
	Measure and report solution or change results
	Recognize and reward team efforts

Typically used by

	Research/statistics
	Creativity/innovation
5	Engineering
1	Project management
3	Manufacturing
	Marketing/sales
	Administration/documentation
4	Servicing/support
	Customer/quality metrics
2	Change management

Notes and key points

The combination I.D./data matrix method

This method is easy to complete; however, great care must be given when relationship or cause and effect ratings are determined. It may be necessary to recheck the entire final matrix in order to verify consistency of ratings.

Refer to Thomas L. Saaty's book Decision Making for Leaders, University of Pittsburgh (1988) for additional information on prioritization processes.

Step-by-step procedure

STEP 1 The team decides what project, issue, or option needs to be prioritized.

STEP 2 Select a particular prioritization matrix method to be constructed. There are three alternatives:
- Full analytical criteria method
- consensus criteria method
- Combination ID/matrix method

STEP 3 The team agrees to prioritize the best data collection appraoch. See example Combination ID/Matrix Method Matrix.

STEP 4 Next, the team determines the strength of the relationship, if any, by comparing each element with all other elements, as shown in the example matrix.

STEP 5 Comlete the Total in, Total out, and Strength columns. This will complete the matrix.

STEP 6 Recheck all symbols and calculations and date the matrix.
