2>How information system benefits organisation?

1>An information system - or application landscape is any combination of information technology and people's activities using that technology to support operations, management In a very broad sense, the term information system is frequently used to refer to the interaction between people, algorithmic processes, data and technology. In this sense, the term is used to refer not only to the information and communication technology an organization uses, but also to the way in which people interact with this technology in support of business processes.

2>The following are benefits of information systems:

• central access
• easy backup
• central distribution of information
• easy record-keeping
• easy tax preparation
• easy customer trait identification

An information system offers a litany of benefits that help to make the process of managing information easier. Central access, easy back up, central distribution of information, easy record keeping, easy tax preparation, as well as easy customer trait identification, are just a few of the benefits offered by an information system. Central access means all organisation members have one point to access all organisationally public information and increases efficiency. Having information in a variety of locations can be cumbersome and cause information to be overlooked. With easy back up, the chances of lost data are decreased and organisational staff will tend to back up more regularly as the system is easy to navigate. Easy record keeping and tax preparation go hand in hand as they both mutually benefit each other. Time is not lost with missing information from poorly kept records, and information is therefore readily available for tax preparation. To receive the greatest benefit overall, it is important to understand that it is an adaptable tool that should progress as your business progresses. Information systems are rarely innovative or 'out of the box' business solutions. They are designed to grow with you and enhance your organisation's information delivery in the process.
