The main purpose of IT within a company should be to ensure that the company’s information is always Available, Accurate and Accessible:

• Available – by ensuring that information is safe from external threats like viruses, spyware, hackers, power failures, physical damage and unexpected hardware failures.
• Accurate – by thoroughly planning, developing or acquiring, implementing and maintaining software systems of high quality.
• Accessible – by ensuring that the hardware used for storing and processing information is at all times powerful and sophisticated enough to meet the needs of the company.
