Quality Conformance Measurements


Weighted non-conformances

For each of the implemented product features is stated:

  • the weight (importance, impact, customer value).
    E.g. in terms of must-have, should-have, could-have.
  • a value relative to the requirements. 
    E.g. the implementation offers significantly more than required (++), more than required (+), conform requirement (0), less than required (-), significantly less than required (--) 

Such a conformance verification table could look like:

Feature Must Should Could -- - 0 + ++ result
F 001 a     a         -20
F 002   a         a   +5
F 003     a     a     0
F xxx a       a       -10

where Must-have requirements are given a value of 10, Should-have's 5, and Could-have's 1 point in this example. 
Implementation deviations from the requirements  are multiplied by respectively -2, -1, 0, 1, and 2. You need to work these factors out to suit your own situation. However, try not to make it a study on itself. 

Or plotted in a diagram that shows the weighted divergence of the requirements over time:
