that has been planned for implementation.
Optimized Disaster Recovery Solution Rather than using the exact
replica of production systems at the Disaster Recovery (DR) site, IBM has
successfully convinced the client to optimize the DR solution. This has
resulted in reducing the computing power to about 50 percent for batch
applications.
Energy-Saving Solutions for Users The client has a large base of employ-
ees and expanding. IBM did an analysis of working atmosphere and patterns
and suggested that the client should convert most of the PCs into laptops.
The benefits of using laptops are multifold with increased mobility of work-
force, greater work efficiency, and business continuity.
Using laptops also helped the client in larger aspects of green environment
contribution with reduced energy, reduced work area, reduced residuals, and
health benefits for employees, and so forth.
The customer is making these changes with the refresh of PCs that are
taking place. (For example, laptops are used for new purchases when refresh-
ing PCs.) ptg

Compilation of the Organization’s Results
Table 11.1 below gives the compilation results of positive impacts on
IBM. Table 11.2 gives the positive impacts on the client. This is an indica-
tive table, and there are many other areas where such an impact can be
demonstrated.
