Application to Organisation Matrix

Map which organisation unit owns each application and which units depend on it, so ownership and reach read together in one grid.

Application to organisation: who owns and who depends on each system

Each application is one row and the five organisation units are the columns. Primary marks the unit accountable for the application; Uses marks a unit that depends on it day to day, so ownership and reach can be read together in one grid.

Application to organisation: who owns and who depends on each system The TOGAF Application/Organization Matrix for London Grid Distribution, a regulated GB electricity distribution network operator. Rows are eight applications from the connections portal to the billing engine; columns are five organisation units. A cell marks the unit as the Primary owner of the application or as a unit that Uses it. Every application has exactly one Primary owner, and the emphasised GIS row is used by four of the five units.

One Primary per row is the accountability rule: an application with two owning units in practice has none. The emphasised GIS row shows why reach matters: four of the five units use it, so a change to GIS is never a local decision for Asset Management alone.

Early in Phase C, to settle application accountability and reveal the shared systems no single unit can change alone.
