Adjusted Best Fit Level THREE

As part of the Best Fit process at Level TWO suppliers are credited with having all of the data that makes up a Level TWO process component. Once the analysis process goes down to Level THREE to determine what data is available in a suppliers product a new picture emerges. If not all data is provided and the client requires those items then customisation costs are incurred. The purpose of this level of comparison is to accurately assess customisation costs and to provide a better comparison between products.

SCREEN SHOTS - Adjusted Best Fit Level THREE

The initial Level TWO comparison showed no gap for CORE components

The original client weighted requirements indicated 25 for item B1.3.1 and there was no functional gap.

Drill down analysis to  review the client weightings assigned to Level THREE for B1.3.1 Record a Person’s Name and Address.

Note the weightings are based on a value between 0 and 10, where 1 is Nice to Have and 10 is Must Have. The values do not have to add up to 100.  In the example the values add up to 90.

Functional gap arises at Level THREE (data level) because vendor does not have a data element that records Middle Name, Other Name, Preferred Name, produces Initials, stores Maiden Name, Common Name

Based on a score of 60 out of 90 (instead of 90 out of 90) a factor of .67 needs to be applied to the items within Level TWO weighting of 25.  After additions for the items the result is 16.67 instead of 25.

The adjusted score for B1.3.1 goes from 25 down to 16.67

After the factor for each item has been applied the CORE total is reduced to 13.25. The same principle applies to each category and the overall total is reduced from 79.1 to 51.16.

Why is that important? Because calculating the true gap is the only way to establish the true cost of customization or component integration to close the gap and know what the real cost of system purchase will be.
