How does a company decide,

which IT systems are appropriate?

which accounting software package to buy?

when it has outgrown its accounting software or when to upgrade the software?

whether to use IT systems to sell products on the web?

whether to establish a data warehouse for analyzing data such as sales trends?

IT systems must be strategically managed.

Strategic management is the process of

determining the strategic vision for the organization,

developing the long-term objectives,

creating the strategies that will achieve the vision and objectives, and

implementing those strategies.

Proper management, control, and use of IT systems is IT governance. IT Governance is defined as:

[A] structure of relationships and processes to direct and control the enterprise in order to achieve the

enterprise’s goals by adding value while balancing risk versus return over IT and its processes. IT governance provides the structure that links IT processes, IT resources and information to enterprise strategies and objectives.

Elements of Systems Planning Phase of Elements of Systems Planning Phase of SDLCSDLCIT governance committee must monitor the IT system through feedback about network utilization, security breaches, and reports on the operation of the system.

IT governance committee should consider:

1) the assessment of IT systems and their match to strategic organizational objectives, and

2) the feasibility of each of the requested modifications or upgrades.
