The paper points out that in a decision task involving the selection of a system from a number of competing systems, a single number or figure of merit is usually inadequate to describe the merits of a given system and that a matrix of numbers representing the important parameters is required. A description is given of the parameters in this matrix. Rules are given for reducing the matrix and for drawing conclusions from the reduced matrix. An example involving a developmental decision is included to illustrate the process.
