SYSE.3:10 - Rationale

Systems Engineering connects a proposed System to the Systems and Work that can make or change it. The systems mantra keeps outside use, architecture, and transformer dependencies in view. In this pattern, engineers inspect those dependencies toward the first unsupported branch and relate later observed Work and change through their own facts. These are two views of the case, not one calendar sequence.

The recursive account is deliberately demand-driven. An exhaustive description of every supplier, tool, team, capability, and possible dependency would be expensive and unstable. One unsupported branch plus one WorkPlan item is already enough to change what the project does next. Further recursion is justified only by that next decision.
