The importance of classification in information architecture.

One of the most important and difficult parts of information architecture is classification. It’s very important to define very strict classification rules and to ensure that there isn’t any overlapping between different information entities. If overlap exists between information it leads for redundancy of data and functionality inside enterprise IT kingdom. I usually insist to create flow chart of the classification rules and not just to be satisfied with classification rules. Team members sometimes don’t understand why I’m so obsessive about that flow chart. But I learned that creating flow chart of classification rules and using those charts to check the classification against real enterprise data save a lot of work in later stages.
