  • 2. R. Attri Engineering Management Series, Paper No. 4, Nov 2011System architecture design is the process of evaluating,selecting and creating architecture of a component‐basedsystem.The objectives of system architecture design are to collectthe users requirement, identify the system specification,select appropriate system architecture, and determine theimplementation details such as platform, programminglanguages, etc.System architecture design should address the advantagefor selecting a particular architecture from otherarchitectures.Copyright © 2011 Raman K. Attri
  • 3. R. Attri Engineering Management Series, Paper No. 4, Nov 2011Define the system on broader level, work out its characteristics.Convert those characteristics to Functional RequirementsConvert functional requirements into sub‐part through which those requirements will be fulfilled.Flow down the Fr into sub‐system requirements and define design parametersCopyright © 2011 Raman K.
