Managing Information Systems / IT Diagram

Any information technology system depends upon a number of key components to help an organization or groups of individuals in terms of information flows. For our purposes the following is our definition of an information system:

“An information system can be any organized combination of people, hardware, software, communications networks, and data resources that collect, transform and disseminate information in an enterprise.”

From this definition we can say that people typically rely on information systems to communicate with each other using a variety of physical devices (hardware), information processing instructions and procedures (software), communication channels (networks), and stored data (data resources). Although this sounds like a description of very modern technology, human beings have been using this process for thousands of years.

In modern organizations, leaders and managers utilize many types of information systems and use a variety of information technologies. An information system is a process that accepts data resources as input and processes them into information products as output. To accomplish this, an information system depends on the resources of people (end users and Information System specialists), hardware (computer equipment and servers) and networks (communications media and network support) to perform input, processing, output, storage, and control activities that convert data resources into information products. The simple IT diagram above offers a simple 6 step process to bring an information system into being. Starting at the top right, these 6 steps are: Communication, Resources, Information, Data, Knowledge and Management. At the center of the chart is also a basic checklist to ensure the essential elements of an effective information system have been considered or for which there is a plan.
