The DIF Calculation

To illustrate the proposed calculation we have outlined the following example. Letýs say that for a specific process flow, the sum of DIF scores provided by five IT SMEs is: 19, 10, and 20. Then you calculate the average DIF and apply the appropriate weights. As shown below, the Overall Weighted Compound Score in this case is 4.93. The range of scores will be largely dependent on the number of SMEs and the applied weight factors. However, in order to constrain the range, we have opted to include only 0 through 5 as the scoring scale.

Dysfunction: 19 sum score / 5 IT SMEs = 
(3.8 avg. * 1.0 weight) = 3.8
Impact: 10 sum score / 5 IT SMEs = 
(2.0 avg. * 1.5 weight) = 3.0
Feasibility: 20 sum score / 5 IT SMEs = 
(4.0 avg. * 2.0 weight) = 8.0
Overall Weighted Compound Score   4.93
