It is a process of collecting and interpreting facts, identifying the problems, and decomposition of a system into its components.System analysis is conducted for the purpose of studying a system or its parts in order to identify its objectives. These systems quickened the pace of daily activities, enabled people to develop and maintain new and often more-rewarding relationships, affected the structure and mix of organizations, changed the type of products bought, and influenced the nature of work. Collectively, they affect both the utility and the life-cycle costs of a product or system. x��X�n�F�G���^�a��#E��$�M�H�&U/�^x�!T�I��j�o��cc� A�MWZǘ�9�����I�����ъ+�g���C�G����lxsq}I��9�xyA>��{�O�pA���' A࣡J���������2Y����CD�?��/������Rf�%�5���&e�рL3T�.r��w��5�X�A'#�^��I�����F59#eI����3]}1%_� ��HÈ�!�| 9bOv|�5����o��2��d�����(�hF2@� K�.�$;�cr������{�O�8\�6i�ަ�W�~�% � ��(635Fŝ�b��ε·. endobj 25 0 obj stream No contractual rights, either expressed or implied, are created by its content.
