Determine Informational Requirements

Identify and analyze existing informational capabilities.

Identify from key users the significant business questions and key metrics that the target user group regards as their most important requirements for information.

Decompose these metrics into their component parts with specific definitions.

Map the component parts to the informational model and systems of record.

Evolutionary and Iterative Development Process

Start with one subject area (or subset or superset) and one target user group.

Continue and add subject areas, user groups and informational capabilities to the architecture based on the organization’s requirements for information, not technology.

Improvements are made from what was learned from previous increments.

Improvements are made from what was learned about warehouse operation and support.

The technical environment may have changed.

Results are seen very quickly; after each iteration.

The end user requirements are refined after each iteration.
