Advantages
information systems have changed the dynamics of running businesses efficiently. The biggest advantage is Decentralization as it allows monitoring of operations at low levels and frees up resources for departmental managers to devote time to strategic activities. An information system is there to empower its users. A database simply provides data, but an information system is all about providing the best information the user needs to do their task more effectively. It also takes into account that different users doing their own specific tasks may need to see their information presented in differing ways. The benefits of an information system follow when the user can quickly access, understand and respond correctly to that information.

Easy for upper-level executives to use, extensive computer experience is not required in operations
Provides timely delivery of company summary information
Information that is provided is better understood
Filters data for management
Improves to tracking information
Offers efficiency to decision makers
Coordination of specialized projects and activities is much better and decision makers in the organization are aware of issues and problems in all departments. Another advantage of IS is that it minimizes information overload, which can be quite common with conventional businesses in the modern era.


Disadvantages
Depending on organization deployment, usage and extraneous factors, some disadvantages related to Management Information Systems can come to the fore. Allocation of budgets for MIS upgrades, modifications and other revisions can be quite tricky at times. If budgets are not allocated uniformly or as per immediate requirements, key functionalities might get effected and benefits might not be realized consistently. Integration issues with legacy systems can affect the quality of output and vital business intelligence reports.

System dependent
Limited functionality, by design
Information overload for some managers
Benefits hard to quantify
High implementation costs
System may become slow, large, and hard to manage
Need good internal processes for data management
May lead to less reliable and less secure data

Thanks for uploading this topics.

Thank you, for sharing advantages and Disadvantages of information system.I would like to shed some light on it's types, which are very crucial and important.

For most businesses, there are a variety of requirements for information. Senior managers need information to help with their business planning. Middle management need more detailed information to help them monitor and control business activities. Employees with operational roles need information to help them carry out their duties.

As a result, businesses tend to have several "information systems" operating at the same time. This revision note highlights the main categories of information system and provides some examples to help you distinguish between them.

Information System Description
Executive Support Systems
An Executive Support System ("ESS") is designed to help senior management make strategic decisions. It gathers, analyses and summarises the key internal and external information used in the business.

A good way to think about an ESS is to imagine the senior management team in an aircraft cockpit - with the instrument panel showing them the status of all the key business activities. ESS typically involve lots of data analysis and modelling tools such as "what-if" analysis to help strategic decision-making.

Management Information Systems
A management information system ("MIS") is mainly concerned with internal sources of information. MIS usually take data from the transaction processing systems (see below) and summarise it into a series of management reports.

MIS reports tend to be used by middle management and operational supervisors.

Decision-Support Systems Decision-support systems ("DSS") are specifically designed to help management make decisions in situations where there is uncertainty about the possible outcomes of those decisions. DSS comprise tools and techniques to help gather relevant information and analyse the options and alternatives. DSS often involves use of complex spreadsheet and databases to create "what-if" models.
Knowledge Management Systems
Knowledge Management Systems ("KMS") exist to help businesses create and share information. These are typically used in a business where employees create new knowledge and expertise - which can then be shared by other people in the organisation to create further commercial opportunities. Good examples include firms of lawyers, accountants and management consultants.

KMS are built around systems which allow efficient categorisation and distribution of knowledge. For example, the knowledge itself might be contained in word processing documents, spreadsheets, PowerPoint presentations. internet pages or whatever. To share the knowledge, a KMS would use group collaboration systems such as an intranet.

Transaction Processing Systems
As the name implies, Transaction Processing Systems ("TPS") are designed to process routine transactions efficiently and accurately. A business will have several (sometimes many) TPS; for example:

- Billing systems to send invoices to customers - Systems to calculate the weekly and monthly payroll and tax payments - Production and purchasing systems to calculate raw material requirements - Stock control systems to process all movements into, within and out of the business

Office Automation Systems Office Automation Systems are systems that try to improve the productivity of employees who need to process data and information. Perhaps the best example is the wide range of software systems that exist to improve the productivity of employees working in an office (e.g. Microsoft Office XP) or systems that allow employees to work from home or whilst on the move.
