The way an organization structures its IT support is a key factor in how effectively it can use information technology to achieve its business goals. IT support structures can range from centralized to decentralized, or a hybrid of the two.
Centralized IT Structure
In a centralized model, all aspects of IT management are concentrated at a single point within the organization. This is typically a data processing or management information systems (MIS) department.
The MIS department may report into a functional business area such as accounting, or directly to the board. The modern trend is for MIS managers or chief information officers (CIOs) to report directly at the board level.
A centralized structure can help an organization save money and promote technology standards. It can also provide better control over the IT function.
However, centralization can make it more difficult for business units to ensure that IT spending is aligned with their strategies. It may also reduce responsiveness to local market demands.
Decentralized IT Structure
A decentralized approach recognizes that some aspects of IT management are best located close to the point of use.
This approach may involve IT staff located within different parts of the organization, allowing for a degree of local autonomy.
A decentralized structure allows for greater flexibility and alignment with business needs.
However, a decentralized approach can lead to the creation of "silos" of information, which makes it difficult for the organization to access and use data in an integrated way.
Decentralization can also make it more difficult to ensure that technology standards are consistently applied across the organization.
Hybrid IT Structure
Many organizations adopt a hybrid model, which combines centralized and decentralized components.
This approach can allow an organization to reap the cost savings of centralization, while also enjoying the benefits of having IT closely tied to the different business areas.
Hybrid structures often involve a centralized IT infrastructure, with IT staff assigned to specific business units.
The Role of the IS Department
The information systems (IS) department, also called the information technology (IT) department, is responsible for developing, running, and maintaining computing devices and information systems in an organization.
This includes designing and implementing information systems, providing support to computer users, creating and managing networks and databases, and securing company systems from unauthorized access.
The IS department may include systems analysts, business analysts, application programmers, operations personnel, and security specialists.

IT staff planning involves recruiting, training, and retaining qualified IS personnel.
Many firms consider this one of their greatest challenges.
Managers must also manage managerial, technical, and clerical personnel.
IT Governance
IT governance ensures that significant organizational investments in IT and IS generate maximum business value and mitigate IT risks.
It involves implementing an organizational structure with well-defined roles for the responsibility of decisions related to the management and use of IT.
IT governance highlights the importance of IT-related matters and ensures that strategic IT decisions are owned by the corporate board, not just by the CIO or other IT managers.
Managing IT for the Enterprise
The strategic and operational importance of IT in business is no longer in question.
Business managers and professionals need to understand how to manage this vital organizational function.
Managing IT includes managing the development and implementation of new business applications, managing the IT organization, and managing the IT infrastructure.
Outsourcing IT
When a company lacks in-house expertise, time, or money to do its own system development, it often turns to outsourcing.
Companies may outsource all or parts of their IS operations to outside contractors, including software procurement and support.
Outsourcing can provide access to specialized skills and resources, reduce costs, and improve efficiency.
End-User Support
End users need liaison, consulting, and training services.
The IT help desk is a central facility in an organization that provides end-user support, such as phone support for trouble-shooting, training, and guidance on end-user development.
Help desks are sometimes outsourced to other companies.
The organizational structure of IT support can significantly affect an organization's ability to effectively leverage information technology. Companies need to carefully consider which model will work best given their unique business needs, size, and culture. Furthermore, the IS/IT function should have the correct staff, management and governance mechanisms in place to support its strategic and operational goals.
