Embedded Mode
     
         A term used by {COCOMO} to describe a project
        development that is characterised by tight, inflexible
        constraints and interface requirements.  The product must
        operate within (is embedded in) a strongly coupled complex of
        hardware, software, regulations and operational procedures.
        An embedded mode project will require a great deal of
        innovation.  An example would be a {real-time system} with
        timing constraints and customised hardware.
