After Establishing the Market Segments and Product Groupings on a Market-Product

After establishing the market segments and product groupings on a market-product grid,the next step is to

A) fill in the appropriate cells with precise statistical data from primary and/or secondary sources.
B) make intelligent "guesstimates" of the market size for each cell using a simple scale from zero to three ("0" = no market; "1" = a small market; "2" = a medium market; and "3" = a large market) .
C) total the vertical columns to identify the greatest marketing synergies and efficiencies.
D) total the horizontal rows to identify greatest operations/production synergies and efficiencies.
E) identify a marketing action for every product-market combination in the grid.
