# Part of a Larger System **Trait Number:** 14 **Layer:** Functional **Bit Position:** 6 (bit 14 overall) **Binary Encoding:** `00000000 00000100 00000000 00000000` **UHT Code (self-encoding):** `00 04 00 00` --- # Icon ![[Icon14.png|200]] ## Definition The entity is **not standalone**. It is functionally or structurally integrated into a broader system, depending on or contributing to the operation of other components. --- ## When to Apply Use this trait when the entity: - **Relies on external systems** to operate fully - Is **modular**, embedded, or otherwise meant to exist **within a whole** - Is **defined by its role within a composite structure** Avoid applying if the entity: - Is **functionally independent** or isolated - Is a **complete, self-contained system** (though its subsystems might still qualify) - Exists without **referencing or contributing to** a larger mechanism --- ## Examples - A gear inside a transmission - A microservice in a distributed system - A battery module inside an EV - A line of code in a program - A single paragraph in a legal document - A control board in a smart appliance --- ## Commentary This trait reflects **functional dependency** and **system composition**. It marks entities that exist **in relation to something bigger**, and whose role, behavior, or existence depends on context. It is crucial in system-of-systems modeling, modular architecture, and MBSE decomposition. It helps identify **integration points**, **interfacing modules**, and **non-standalone components**. --- **© 2025 Steven Holland. All rights reserved.** [[Copyright Statement]]
