5. Design definition process (INCOSE Systems Engineering)

Introduction

Input	Process	Output
– Life cycle concepts – System function definition – System requirements – System functional interface identification – System architecture description – System architecture rationale – Preliminary interface definition – Preliminary TPM needs – Preliminary TPM data – Architecture traceability – Interface definition update identification – Implementation traceability – Life cycle constraints	> Prepare for design definition > Establish design characteristics and design enablers related to each system element > Assess alternatives for obtaining system elements > Manage the design	= Design definition strategy = System design description = System design rationale = Interface definition = TPM needs = TPM data = Design traceability = System element descriptions = Design definition record
