The IT department
The support of information systems in organisation requires the development of an IT organisation, a department which supports the procurement, delivery and continued service of a range of enterprise systems and other systems in the organisation. How this is to be structured is a matter of debate. It can be a centralised department which serves all the needs of the organisation and where IT is centrally procured. It can be decentralised, where each function or section of the organisation has its own IT unit. An alternative approach is federal where some key functions of IT are operated central and some locally. IT may be organised around its customers or around the technology. Often the temptation is to take a too technical view.
Additionally an IT department needs standards and processes. Standards may include service standards such as ISO20000, governance standards such as ISO 38000 and specific specialist standards such as the ISO270001 security standards. Processes will cover approaches to development such as agile methods like Scrum and service processes such as the ITIL best practice processes. These need to be implemented over time; structure, skills and processes need to build up and the IT department needs to be a learning organisation, relating to the organisation it serves and aligned to its business.
