Q

GIVE 2 DETAIL DESIGN REQUIREMENTS

A
  1. Procurement and acquisitions of system components begin, components are combined and integrated into a next higher assembly and a physical model of a system is constructed for test and evaluation.
  2. The integration, test, and evaluation steps constitute a bottom up activity and should result in a CONFIGURATION that can assessed for compliance with initially specified customer requirements.
