Processes for Engineering a System
The purpose of this Standard is to provide an integrated set of fundamental processes to aid a developer in the engineering or re-engineering of a system.
TABLE OF CONTENTS Processes for Engineering a System
Annex E: System Technical Reviews (Informative)
The system technical reviews of Table E.1 are related to engineering life cycle phases and are relevant to the system element of applicable building block developments. They are not directly related to enterprise- based life cycle phases (see Annex B); however, technical review exit criteria include satisfying the exit criteria of the applicable enterprise-based life cycle phase.
| PHASE | ENGINEERING LIFE CYCLE PHASE REVIEWS |
|---|---|
| Pre-System Definition | An alternative system review, if applicable, considers all concepts looked at and selects a preferred concept for further development that has the potential for satisfying identified stakeholder requirements. Assesses progress toward converging on a viable, traceable set of system technical requirements that are balanced with cost, schedule, and risk. |
| System Definition | A system requirements review validates that the set of stakeholder requirements is complete, consistent with acquirer's intent, and understood by the developer. A system definition review demonstrates convergence on and achievability of technical requirements and readiness to initiate the Subsystem Design Phase. |
| Subsystem Design | A subsystem requirements review, held for each subsystem-layer building block development, validates that the set of assigned and other local stakeholder requirements is complete, consistent with stakeholder's intent, and understood by the developer. A system preliminary design review for each subsystem building block development confirms that a) subsystem building block specifications have been defined appropriately; b) subsystem building block end product designs satisfy requirements assigned from the parent building block; c) enabling products for the associated processes have been defined... |
