IT/BUSINESS STRATEGIESFlexibility and agility key to CIO success in 2008 (Carol Hildebrand, Contributor 12.13.2007 )

For many CIOs, the primary trend today revolves around a continuing and increasing business demand for IT agility, to match the quick pace of business. In an age where business decisions are made in minutes and hours rather than days and weeks, CIOsfind themselves looking for ways to make sure that information is available quickly and comprehensively.

"Businesses are calling for more Businesses are calling for more flexible responses, and an IT infrastructureflexible responses, and an IT infrastructure that will allow IT to respond more that will allow IT to respond more quickly to changing business requirements and needs,"quickly to changing business requirements and needs," said Andrew Bartels, a research analyst at Forrester Research Inc. in Cambridge, Mass. "Businesses need to be able to be more nimble and react more quickly, and CIOs will be looking for technologies that allow IT to do that."

Green IT. The focus of Green IT that came to the forefront in 2007 will accelerate and expand in 2008.

Unified Communications. Today, 20 percent of the installed base with PBX has migrated to IP telephony,

Business Process Modeling. Top-level process services must be defined jointly by a set of roles

Metadata Management. Through 2010, organizations implementing both customer data integration and product integration and product information management

Virtualization 2.0. Virtualization technologies can improve IT resource utilization and increase the flexibilityneeded to adapt to changing requirements and workloads. However, by themselves, virtualization technologies are simply enablers that help broader improvements in infrastructure cost reduction, flexibility and resiliency. With the addition of automation technologies – with service-level, policy-based active management – resource efficiency can improve dramatically, flexibility can become automatic based on requirements, and services can be managed holistically, ensuring high levels of resiliency. Virtualization plus service-level, policy-based automation constitutes an RTI.

Mashup & Composite Apps. By 2010, Web mashups will be the dominant model (80 percent) for the creation of composite enterprise applications.

Web Platform & WOA. Software as a service (SaaS) is becoming a viable option in more markets and companies must evaluate where service based delivery may provide value in 2008-2010.

Computing Fabric. A computing fabric is the evolution of server design beyond the interim stage, blade servers, that exists today.

Real World Web. The term “real world Web” is informal, referring to places where information from the Webis applied to the particular location, activity or context in the real world.

Social Software. Through 2010, the enterprise Web 2.0 product environment will experience considerable flux with continued product innovation and new entrants, including start-ups, large vendors and traditional collaboration vendors
