This is true, because making a change to a software system requires an understanding of how the part being changed fits into the system and of the potential ripple effect the change may have on the system. Understanding the software system is a time(More)
Choosing the proper hardware and software tools is only one phase of implementing and managing Decision Support Systems. Generally, organizations pass through three phases in adopting DSS. The first phase is concerned with learning and experimenting with the system. In the second phase management assesses the benefits and rewards of end-user computing. In(More)
