In a recent blog post by Jim Harris called Data Quality is not an Act, it is a Habit the term “golden mean” was mentioned.
In using these terms I think we mostly are aiming on achieving extreme uniqueness. But we should rather go for symmetry, proportion, and harmony.
The golden copy subject is very timely for me as I this weekend is overseeing the execution of the automated processes that create a baseline for a golden copy of party master data at a franchise operator for a major brand in car rental.
In car rental you are dealing with many different party types. You have companies as customers and prospects and you have individuals being contacts at the companies, employees using the cars rented by the companies and individuals being private renters. A real world person may have several of these roles. Besides that we have cases of mixed identities.
During a series of workshops we have worked with defining the rules for merge and survivorship in the golden copy. Though we may be able to go for extreme uniqueness in identifying real world companies and persons this may not necessary serve the business needs and, like it or not, be capable of being related back into the core systems used in daily business.
Therefore this golden copy is based on a beautiful golden mean exposing symmetry, proportion, and harmony.
