Integration strategy for information resources
(starting from a legacy perspective)


Information Dynamics







Of the average legacy database for administrative applications, at least 80% is susceptible to re-using information from other databases. And it is not about a personís name and address, only.

Legacy databases are updated independently. Paradoxically, through lack of coordination, over time databases diverge where they should always be similar, i.e. for about 80 percent.

This is the most difficult symptom to appreciate, with exponential rewards when dealt with outright. Donít rely on standardization, only. On the average, at most 20% of information is characteristic. It is critical to maintain, even emphasize, the difference, though. Especially operational employees understand how such information differentiates positively, i.e. how they rely on it for for quality, success, etc. Count on them to resist over-standardization. Donít push beyond the balance. Compliance with absolute standards might indicate loss of competitive edge.

Obviously, operational decisions occur in the here-and-now. A properly grounded decision often requires a time series of information (possibly including how information definitions and structure may vary over time).
