Compile list of ITs by empirical surveys. Experts rate ITs according to their
assessments of functions or features of the technologies.
Limitations
Narrow representation: arbitrary and limited
choices of features and functions, few ITs
Static: snapshots few and far in between Not scalable: more ITs lower reliability

“Over the past few years, we have seen the ERP vendors-led by SAP-move into different business areas,” says Byron Miller, an analyst with the Giga Information Group. “The competitive advantage of just having ERP has diminished. The next big thing beyond ERP is supply-chain management.” Links between groupware and ERP applications speed users' access from within a groupware application to key business data, such as purchase orders, inventory, customer histories, and other supply-chain information.

When expert knowledge is not readily
available, this approach offers maps of IT domains or sub-domains.
A new technology’s cluster membership
may suggest its broader type.
Taxonomy is useful for vendors in
product/service labeling and for adopters in IT portfolio management.

Computational discourse analysis based on
co-occurrence and hierarchical clustering can help us explore complex relationships among IT concepts in a representative, dynamic, and scalable way.
Social-technical approach: we used social
artifacts (language/discourse) to chart technological terrains.
Effective information management and
effective IT management go hand-in-hand.
