Worldwide IT spending is set to grow 3 percent in 2012 compared to 2011, according to new statistics from Gartner. Gartner’s latest 2012 global IT spending forecast is US$ 3.6 trillion, compared to US$ 3.5 trillion last year and up slightly from Gartner’s previously released 2012 IT spending forecast of about US$ 3.58 trillion (a 2.5 percent year-over-year increase).

Telecom Equipment, Enterprise Software Lead the Way

In addition to tracking overall IT spending trends, Gartner also tracks spending trends in the IT subcategories of computing hardware, enterprise software, IT services, telecom equipment and telecom services. The global telecom services market, which led all subcategories in 2011 with impressive 17.5 percent year-over-year spending growth, continues to be the largest IT spending market this year, with an expected 10.8 percent year-over-year spending increase.


Gartner says telecom services growth is expected from net connections, especially in emerging markets, as well as from the increased use of multiple connected devices, such as media tablets, gaming and other consumer electronics devices, in mature markets.

Enterprise software, which had the second-highest rate of year-over-year growth in 2011 (9.8 percent), also has the second-highest rate in 2012 (4.3 percent). And although IT services spending is only expected to rise 2.3 percent this year compared to last year, Gartner forecasts spending on enterprise cloud services will increase a healthy 19.8 percent, from US$ 91 billion in 2011 to US$ 109 billion in 2012.

Gartner analysis indicates that although business process as a service (BPaaS) still accounts for the vast majority of cloud spending by enterprises, other areas such as platform as a service (PaaS), software as a service (SaaS) and infrastructure as a service (IaaS) are growing at faster rates. By 2016, Gartner expects global spending on public cloud services to equal US$ 207 billion, about a 90 percent increase from this year’s anticipated figure. 

Cloud Computing Requires Change Management

While cloud services spending grows at a rapid pace, cloud users should keep the need for change management (CM) for their implementations in mind. Change management in this context refers to a process to prepare and support people through changes triggered due to cloud computing and to ensure the achievement of desired business objectives put forth in the business case for the cloud implementation.

As recently reported by CMSWire, a Morgan Stanley Survey indicates there is a steady shift in workload moving out of on premises to cloud environments, and more than 20 percent of workloads already moved off premises during the last six years, reaching a key inflection point for accelerated adoption. It is expected that by 2014, only 62 percent of workloads will be run on premises.

Cloud implementation impacts the way an IT organization is being managed. There will be minor, major and significant impacts depending on an organization’s IT maturity, type and amount of workloads that are moved to a cloud platform.

Typically, by moving applications and workloads to a cloud, IT team’s operation model will shift resulting in changed roles, responsibilities and new expectations for the IT organization. Similarly, moving to cloud computing requires service management (SM) process consolidation and integration supported through an effective IT governance structure; the depth of integration and the type of IT governance structure mainly depends on cloud deployment models.

This clearly indicates that there will be changes to the target state when compared with the current environment. Every change needs to be listed along with the consequent impacts of each change and a plan to manage these impacts through change enablers.
