Are the current benefits B greater than or equal to the cost C of the benefits?
If yes for either, then the current benefits B and/or cost C remains intact, and, precautions are necessary to ensure B and/or C is not negatively affected by any proposed system change
If no for either, then identify the change (delta) necessary for B to be equal to or greater than the costs. This can be a delta to B or C or both. Identify the characteristic zone and team system characteristics impacted and proceed to the solution analysis.
