I created the following Excel worksheet to offer a cross-comparison of the Document Management features and capabilities of SharePoint vs. other DMS on the market.
Credit to Wikipedia for the main categories and fundamentals. Obviously the grading system is opinion-based however I added extensive comments in to each of the SharePoint score cells to back up my points.

Spreadsheet Instructions

Edit data only in color coded cells – white cells contain formulas and should be left alone)
Note: If you need to add factors or categories, please see the example tab for more instructions

  • Title your options: replace “Option 1”, “Option 2” with your option titles
  • Title categories for consideration in column A : replace “Category 1”, “Category 2” with your category labels
  • Add factors for decision in each category in column B (for a job, this might be commute, pay, etc.)
  • Assign weights to categories (column C) so that they add to 100 (see below cat weight column for total). This forces you to understand how important these categories are to you relative to each other
  • Assign weights to each factor within the categories (column D) so they add to 100 (see above factor weights for total). When assigning weights to factors, concentrate on their relative importance, ignoring factors in other categories
    • Note: when your weights add up properly, you should have no more red totals visible.
  • Fill out blue areas with scores from 0-10
    • Note for negatives, reverse your thinking (so a high score on a negative like Risk means it’s NOT risky)
    • ┬áNote that as you edit scores, the weighted averages are shown as subtotals and absolute totals along the bottom.
      For “yes/no” factors, use 0 for no, and 10 for yes.
