On aspects of automated information system efficiency evaluation at different stages of lifecycle

The article continues a series of works which are devoted to complex systems efficiency evaluation at different stages of the lifecycle. The most famous methods of automated information systems (AIS) efficiency evaluation are considered and their benefits and limitations are shown. The recommendations to AIS efficiency parameters selection at different stages of the lifecycle are presented. The authors suggest an approach to choose the AIS efficiency evaluation method. The areas and conditions of current efficiency evaluation methods applications for certain AIS are determined as well. The practical use of the developed efficiency evaluation techniques is shown.
