SYSE.3:2 - Problem

An architecture candidate proposes an organization of the System, but it does not make that organization exist. For example, a selected module, interface, placement, control relation, or configuration may depend on changes to pre-existing materials and Systems, first constitution of new Systems, integration Work, and Systems capable of performing that Work. Those transformer Systems can themselves need new capabilities, tools, Methods, resources, configuration, or prior change.

A single decomposition rarely exposes all of these dependencies. A component tree follows the proposed System; a WBS follows intended Work; an organization chart follows one organization; a platform inventory or diagram follows selected technical means. None alone answers which actual Systems can perform the needed Work under the stated conditions. The engineering difficulty is to connect these descriptions without merging architecture, intended change, transformer capability, WorkPlan, performed Work, and evidence into one diagram.
