Downloadable customer prospect priority matrix. Use this matrix to prioritise your customer or prospect investment and development activity. Use your own criteria to grade your A, B, and C products and customers/prospects (eg., size, growth potential, 'fit', value, margin, etc) and insert customers/prospects into the relevant boxes. Box numbers signify priority in terms of development investment and resource allocation (1 = highest, 5 = lowest). Dark boxes offer less return on investment. See also the Boston Matrix.
