Phase B, Business ArchitectureDerived from TOGAF

Business Interaction Matrix

Record which organisation unit provides which business service to which other unit, so every internal handoff is written down once and owned.

Business interaction matrix: which unit provides which service to whom

Five organisation units appear as both rows and columns. A filled cell names the business service the row unit provides to the column unit, so every handoff inside the distribution business is written down once and owned.

Business interaction matrix: which unit provides which service to whom A Business Interaction Matrix, the TOGAF Standard 10 Phase B artifact, worked for London Grid Distribution, a GB electricity distributor. Five organisation units run down the side as providers and across the top as consumers. Each filled cell names the business service the row unit provides to the column unit, such as Network Operations giving planned outage windows to Connections. The diagonal stays blank and the emphasised Connections row shows a new connection touching every unit.

Read the Connections row beside the Connections column and the point appears: one new connection draws services from all four other units. An interaction that sits in no cell is an undocumented dependency, and undocumented dependencies are where handoffs fail.

In Phase B, when handoffs between units are undocumented or disputed and dependencies need to be made explicit.
