144. Grid Analysis (also known as Decision Matrix analysis or Pugh Matrix analysis) is a useful technique to use for making a decision. Decision matrices are most effective where you have a number of good alternatives and many factors to take into account. The first step is to list your options and then the factors that are important for making the decision. Lay these out in a table, with options as the row labels, and factors as the column headings. Next work out the relative importance of the factors in your decision. Show these as numbers. We will use these to weight your preferences by the importance of the factor. These values may be obvious.
