DOWNSIZING AND RIGHTSIZING
Downsizing: The downward migrations of business applications are often from mainframes to PCs due to low costing of workstation. And also today’s workstations are as powerful as last decade’s mainframes. The result of that is Clients having power at the cost of less money, provides better performance and then system offers flexibility to make other purchase or to increase overall benefits.

Rightsizing: Moves the Client/Server applications to the most appropriate server platform, in that case the servers from different vendors can co-exist and the network is known as the ‘system’. Getting the data from the system no longer refers to a single mainframe. As a matter of fact, we probably don’t know where the
Significant cost savings usually are obtained from a resulting reduction in employee, hardware, software, and maintenance expenses. Additional savings typically accrue from the improved effectiveness of the user community using client/server technology.
Downsizing is frequently implemented in concert with a flattening of the organizational hierarchy.
Eliminating middle layers of management implies empowerment to the first level of management with the decision-making authority for the whole job. Information provided at the desktop by networked PCs and workstations integrated with existing host (such as mainframe and minicomputer) applications is necessary to facilitate this empowerment. These desktop-host integrated systems house the information required to make decisions quickly. To be effective, the desktop workstation must provide access to this information as part of the normal business practice. Architects and developers must work closely with business decision makers to ensure that new applications and systems are designed to be integrated with effective business processes. Much of the cause of poor return on technology investment is attributable to a lack of understanding by the designers of the day-to-day business impact of their solutions.
Downsizing information systems is more than an attempt to use cheaper workstation
