Information system is a system which is used for organizing and processing information, generally computer-based. Also, it is a useful system within a business because it manages the development and operations of the business

’s information. The importance of information systems are growing. As data is now taking towards a digital form, instead of just a paper-based. Its good point is that the data is becoming readily available and become more secure. It prevents the data from unauthorized access. Like in hospitals information systems are very helpful, your data is stored in computers and where ever you are in the hospital your details are available at a few key strokes.
In the world of globalization, Information system is such where data are collected, classified and put into process interpreting the result thereon in order to provide an integrated series of information for further conveying and analyzing. In a progressively more strong-willed worldwide atmosphere, Information System plays the role as ‘enabler and facilitator’, which endows with tactical values to the officialdom and considerable step up to the excellence of administration. ‘An Information System is a particular type of work system that uses information technology to detain, put on the air, store, retrieve, manipulate or display information, thereby partisan one or more other work structure’. In totting up to taking sides assessment making, co-ordination and control, information systems may also help managers and workers investigate problems, envisage complex subjects and generate new merchandise or services.
Work systems and the information systems that support typically undergo at least four phases: a) initiation, the process of defining the need to change an existing work system
b) Development, the process of acquiring and configuring/installing the necessary hardware, software and other resources
c) Implementation, the process of building new system operational in the organisation, and
d) Operation and maintenance, the process concerned with the operation of the system, correcting any problems that may arise and ensuring that the system is delivering the anticipating benefits. The management of these processes can be achieved and controlled using a series of techniques and management tools which, collectively, tend to be known as Structured Methodologies. Two important methodologies:
 PRINCE (Projects IN a Controlled Environment), and
 SSADM (Structured Systems Analysis and Design Methodology), developed by the Central Computing and Telecommunications Agency (CCTA), are used widely in the UK public sector and in some Developing Countries, like Bangladesh, Pakistan, Nepal etc. Prior to comment on the application of these methods in the Developing Countries, it would be pertinent to describe brief outlines of these methodologies.
Information technology is a very important malleable resource available to executives.[2] Many companies have created a position of Chief Information Officer (CIO) that sits on the executive board with the Chief Executive Officer (CEO), Chief Financial Officer (CFO), Chief Operating Officer (COO) and Chief Technical Officer (CTO).The CTO may also serve as CIO, and vice versa. The Chief Information Security Officer (CISO), which focuses on information security within an organization, normally reports to the CIO.
