A more informative method of scoring is to have a three-dimensional matrix.  Not only “fully complies” etc. but which version - “current”, “will be released within 6 months”, “will be released within 18 months”, “will consider for future release”, “would not consider”.  The latter pieces of additional information should give a better, although only approximate view, of the direction in which software development is headed.  There are arguments for and against this approach, but if more distant horizons are reflected by discounting the scoring, purchasers may get more information than the two-dimensional somehow complies/does not comply traditional responses.  As billing software is evolving to meet new needs (industrial or trade waste, for example), future directions are significant for potential users
