# Configuration Management

## Key Elements

### Model

Variants of end items can be defined by using the model codes. A Model is similar to a variant or a configuration ID.

### CI Matrix

Administrator/project manager has to define which units and sequence numbers are associated with an end-item to be under configuration control.

### Baseline Type

The Baseline type code classifies the Baseline documents. Baseline types are:

- Allocated baseline
- Functional baseline
- Physical baseline.

### Change Type

The Change type code classifies the Enterprise Change Requests.

### Workflow

Changes could be processed by the workflow engine.

### Lifecycle

Release procedure to be assigned to a change type.

### Embodiment Code

Embodiment codes are to confirm incorporation of changes:

- E - Embodied
- N - Not embodied.
- S - Satisfactorily embodied ( requires a Waiver/Deviation)

### Embodiment Point

Embodiment points define places for incorporation of changes:

- H - Retrofit before delivery (in house)
- L - In-line embodiment (during manufacturing)
- S - Retrofit after delivery (in service).

### Reference code

The reference codes are defining relations between different changes. The reference is a bi-directional relation. If Reference #1 differs from Reference #2 the inverse record is created automatically.

### Affected Disciplines

Affected disciplines are the disciplines being affected/involved by a change.
